Ok, couple updates.

Got the front coil springs swapped out, brought the front end up about 1-1.25", and it doesn't bottom out anymore, unless I hit a bad dip at speed. Much much better, and can love with it. Think I could have went to a slightly higher rate, but I will live with it. I may see if I can install a slightly higher bumper stop, will see.

My TrueTrac, ring & pinion, and install kit came in to rebuild the rear, just need to order some ARP ring gear bolts. The ones that come in the kit have a head where you need to use a thin wall socket, and still is a PITA, the ARP ones I'm told make it much easier. Should get this knocked out in next couple weeks.

Still not happy with the fuel sending unit, may have to go to a vertical float type, it just isn't accurate to my liking.

The Tanks, Inc efi tank isn't working as well as I had hoped, under a half a tank it can suck air, and as it reaches a 1/4 tank, it gets worse. I did at one time run it out of gas, had to restart twice to get it up to a pump to fill it, but going slow, it just about sucks the tank dry, was about 1.5-2 gal at most left in it, calculated by the amount it took to fill it back up. I may have to resort to getting a Rick's tank, the one with added baffling.

Still have some tuning to do, and am really starting to think the throttle body is too small. It's a CTS-V 90 or 92mm, forget which one, but believe it's giving up flow past say like 4500-5000 RPM. Think I'm going to look into a 102mm, see how that responds.

Friend took a short vid, figured I'd post it:

https://youtu.be/uIMgNqFaqLg

Still need to fix the exhaust, tailpipes are uneven and IMO too low, and they are about 1.5-2" too long, need to tuck them in some. That stuff drives me nuts.

My paint/body guy picked up my 'bird, it's in-process, and need to swap engine in 442, plus add the Vintage Air before the 'bird comes home. I'm swamped. Trying to fix up the house, I am dyeing to move, need more garage space, and sick of the area I live in....

Looks great and sounds great, too! But I agree with you on the tailpipes - too low and too long.

Yeah, I will try to play with the tailpipes and tips this weekend, think I can get it better.

I loosely fit the exhaust, and took it up to a friend's shop to have welded. We had worked on other stuff for hours, was getting close to the end of day, so we got it to a point and shrugged, saying we will get back to it. He put the floor stand under the X pipe, cranked it up, and tacked it, figuring it would droop some once relaxed. It didn't. So will have to see what's up back there, see if I can get it in place. He had the X assembly on a bench to finish welding, it may have moved a little then, too.

I may actually have to just get another kit and try again, sadly, but will see.

This Thursday I go to a buddy's shop to have the rear rebuilt, finally! Then will get the pinion angle stuff dialed in.

Pretty busy, been helping others with their' projects, and have a couple of my own aside from the Judge.

Trying to get the house ready for sale, hoping to move in the spring (fingers crossed).

The 442 is getting a Olds 495 stroker, and a Vintage Air setup, need to get that done before the 'bird comes back from the body shop. Hoping to have the engine in by end of this coming weekend. (Had a bunch of cleanup to do)

Through times of crappy weather, I've been working on the 'bird interior stuff, refoam/recover rear seats, assemble the new dash, prep parts so they can just be bolted on, stuff like that. Trying to make it assemble easier once I start on it.

I did get time to readjust the tailpipes on the judge, much much better, but still not up to my liking. I'm just going to have to spring for new headers and X pipe setup, I can't see any other way to make it 'right' with the existing headers' uneven collector angles.

Working on the tune as well, keep getting closer as I learn more of the system, MPFI is a little more complicated and not as easy as a TBI setup. But I will get there.

I had 3 injectors slowly fail, which complicated tuning efforts. In an attempt to isolate my issues, I retarded timing and fattened it up a bunch, in stages, and was reading plugs on the way. 3 plugs were completely dry no matter what I did. Doubt it's from debris in the fuel system, but will see.

Going to pull all the injectors and send them into a service, have them cleaned, tested, and balanced.

I did get the 442 finished up, have a few things a friend is going to do for me, charge AC, R&R some wheels/tires, swap an axle, stuff like that.

Body guy says he has the back half of the 'bird done, haven't spoke much with him thru the holidays, will probably reach out this week or next, see where he's at with it.

It was a tough one to figure out, it's not like they went dead all at once, they slowly started flowing less and less.

I will probably pull the intake too, and have it gasket matched to the heads. I cleaned them up a little, but they really could use a proper job. Heads are Butler 315cfm, so know they have a CNC program for the intakes.

Got some stuff done, drip rail moldings, window fuzzies, and started mocking up the wheel opening moldings.

Drip rail moldings, there was some paint build up on the rails, prevented the molding from fitting the way I liked, so took a razor blade and trimmed some high spots, and any area that exposed primer, I hit with some clear nail polish. The note in the catalog mentions that some minor imperfections may appear on the moldings, and mine had 2 very small areas that had dents, not very noticeable, such is life.

Window fuzzies. So these were the PUI marketed fuzzies, which was on the car before, unfortunately though, the holes didn't line up from last set. As all are probably aware, the 1/4 window curve is the challenge when installing these, and you have to move it back and forth to get the closest fit. After about 4 hours of frustrating, sweating, cussin' work, handful of stripped and snapped screws, 2 broken drill bits, I had a satisfactory install. The passenger side has a slight uneven lay on the outside panel, the thin rubber strip, but think I'm just going to leave it. Have to stare at it to see it, so think I can live with it. The 1/4 glass doesn't go down far enough to get one screw in, not sure if I'm going to go through the trouble to pull the glass or not.

Most of the day was spent on organization, like laying out all the bolts, clips, etc, and review of panel fitment/alignment. Also clean up of 'construction debris' from the body shop. The engine and frame rails, as well as a few other areas were covered in plastic by the body shop, all that coming off made even more of a mess.

Made a list of items that were missing, will have to place an order here soon so I can finish up the exterior portion of the build.

So will focus on the wheel opening moldings next weekend, and building out the bumper. I need to clean/prep the tail lens buckets, clean up a few of the brackets, ensure I have all the lower valance pieces/bolts, and tape off the body so there's no damage from potential contact when installing.

I will post pics of that stuff once it's done, the stuff I did this past weekend wasn't very flashy, so no pics, unless someone asks for specific ones.

@ time spent this past weekend = 14 hrs

Busted Knuckle Physical Damage Score: (1-5 scale)
* Nice knot on head from banging it on the exposed inner roof - 2
* Associated lesion with above incident - 2
* One nasty metal sliver from a 'curly-cue' drilling hole - 2
* Minor random abrasions, elbows, knees, and neck - 1
* TOTAL Score - 7

Difficulty Scale of Work Performed: (0-10 scale)

Drip Rail Moldings - 3
Window Fuzzies - 5

HA! love the difficulty humor notes! I should have done that.

early on mine would have read: "unforseen weld spatter while under car on back burning thru shirt unbeknownst to me and freaking out when it makes it to the skin" rating: 10 out of 10. still have the shirt.

super nice car. dig it.

Thanks! Yeah, as the project progressed, and I became really busy (not just cars stuff), I started not giving updates as much as I would have liked, so, the humor part kind of dropped off!

I'm still settling in after my move, and had to live in a temp location for almost a year while my house was being built. My stuff was spread over multiple locations, but am now just starting to get more time to focus on finishing this car. It's killing me not being able to drive it!

In order to move the 442, I had to install the new stroker engine, and a handful of parts. That car too needs attention, and is still at an alternate location. I need to get on that too.

And to add to all mentioned already, the 'bird is in paint/body, and is nearing completion. I have to make room for that, and update the thread I started on for it. That thread was, um, started when I had been drinking, so have to see if I need to start a new one or not! Heheh!

So in an effort to speed the process, I ended up buying a fresh Moser 12 bolt, Tru Track, 342s, and swapped it over. Still finishing up that swap, and correcting a number of other small things.

Guess I will sell the old Moser rear, thinking I will include the fresh rebuild parts, and price it basically to recover the cost of the rebuild parts.

The shop I was going to have do my rear before fell through, because I stripped a couple teeth off the ring gear, was not happy. Had to replace the flexplate on jack stands, not fun!
To top it off, a dowel hung in the bellhousing, took a solid day to wrestle that thing out! And, the dowel came out with the trans. Uhg. Luckily, I was able to just pull it back into the block, the long bolts really helped lining it all up. But, it's all done now, thankfully.

Should have the thing all buttoned up within a week or so, need to bleed the brakes, and fix some lingering minor stuff.

One of the punch list items I needed to address was a tip-in det issue. I worked the timing table again and again, and couldn't seem to get rid of it. Long story short, went back to square one, did all the initial & running timing checks, and found there was timing creep at tip in and above 3000 RPM. To correct, inductive delay settings needed to be adjusted.

In adjusting that, I found that changing the value had no effect on the creep, so replaced the whole ignition system, new coil, new dizzy, new CD box, wires, plugs, and went over the whole ignition portion of the harness. That did it, was now able to get response from the inductive delay setting.

In testing the second time, to view the timing marks better, I pulled the air intake tube off, which helped considerably. With the tube off, I now was hearing a 'pop' back into the intake plenum. Went over the lash adjustments multiple times, and couldn't resolve it.

Broke out the bore scope, and tried to fish it down there thinking maybe something found it's way into the intake tract and boogered a valve. Was not able to see very well, so pulled the intake. Still no go with the bore scope, all the intake valves looked good. Made sense, since the 'pop' was blowing back into the intake tract, so I started to fill the cyls with compressed air.

And, air, with all the rockers off, was leaking into the exhaust crossover, indicating a head gasket issue.

Pulled the head and found this:

Yeah. Not good.

These heads were from the 461 build, and are Butler 315cfm heads, and knew at some point I would need to upgrade to more flow, they were holding the power back. But, really was hoping it wouldn't be under these conditions.

The block is good, cleaned it up and can still see the hash marks on the deck.

I rocked the pistons back & forth, shining a light on the top rings, and saw no cracks, so rings are good. There are also no scratches/gouges in the walls. So dodged a bullet there.

So, I ordered a set of Butler CNC 340cfm round port E-heads, and a new intake to match. I'm going to disassemble the existing heads, and send the PAC springs, retainers, locks, and pads/cups to be used on the new heads, helping with the cost.

I spoke to Butler about the head, and yes, can be fixed with no impact to integrity, but it's done by an outside vendor, and there is a backlog.

I will send both heads to Butler, have them both checked and the one repaired, and sell them to help offset costs more. Uhg.

Anyway, mysteries solved, lessons learned, and am on the path to recovery. (Engine too!).

How does this happen in the first place? I can't say that I've seen something like that before.

It starts with a blown head gasket that goes unnoticed and progresses to that.

Without the intake tube on I was able to hear the pop back into the intake track, but before that, with the intake tube on, I didn't hear it, and suspected other problems causing my issues.

What blew the head gasket in the first place? Simply put, this is usually caused by a lean and/or detonation condition. And it went unnoticed.

More simple, human error.

This happened to a combustion when a titanium retainer lensed and the exhaust valve dropped. The valve head broke off, the stem stuck in the guide and caused havoc. My local machine shop welded up the chamber, installed new seats and machined it to get the same size as the rest for $500. Looking at the retainer under a microscope I noticed a small oclusion where it broke. Your head can definitely be fixed.

Bummer!

Oh yeah, it can be fixed, and the cheap way out would have been to have them ported to 340cfm at the same time. But. The lead time is brutal.

Butler sends them out to fix, they don't do it anymore, but they gave me the contact who does them for them, and I will just send the bare head there to be fixed.

After I have the boxes from the new heads, I will use them to ship the broke one to be repaired, then shipped to Butler's. I will ship the other head in the other new box directly to.

I have like $1100 in springs (#1243), retainers, locators, locks, and lash caps. It's all PAC stuff, @ 1000 miles on them. Butler uses the same springs, so opted for those, Comp titanium keepers, locks, and think they are Manley retainers. Again, to save time.

Not sure I will set the original heads back up with the same stuff and sell them, or sell the springs and stuff separately. I will figure that out when I reach that point. But the idea is to sell the original stuff, corrected, to offset the cost of the new ones.

I have all the part numbers etc for everything and will have work orders for the repairs & assembly, so it's not like there will be lack of confidence of the work when selling them.

Someone may like the fact that there's a set done and not have to wait for them, who knows. But I will obviously take a loss, just not as great of one.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
