Finally got it on the road, whew. Still have a few things to do, front end alignment, exhaust welded up, AC charged, and some minor tuning stuff.

Have detail work to do too, as well as a couple scratch repairs that occurred during assembly. Uhg.

Running a little warm, in traffic, it got to almost 205, hotter than I like it to be, prefer the 190 range. May just be some timing needs to be pulled out, I will play with it.

Weird issue with the DBW too, sometimes from a stop, I hit the peddle, and nothing happens. If I let completely off, and try again, it works. Or if I keep depressing until it gets to like a 1/4 throttle, that works too, but it's spinning at that point.

Awesome build. I skimmed thru it from the beginning and I may have missed it but what is “DBW”? I’m guessing drive by wire?

I’m considering a similar build, and just found this one. Mine is a 70 GTO my dad and I rebuilt, that he has lost interest in. It’s a “finished” car, but he’s decided to pass it on to me as he doesn’t get to enjoy it much anymore. It’s a fairly original setup (not numbers matching and nowhere near concours, just basic 70 GTO stuff). I’m considering stuffing my IA2 motor in with a different cam (currently setup as a race motor), along with fuel injection, and air conditioning (vintage air). May drop the stance down an inch or two and stuff some nice 17” or 18” wheels under it.

Anyway, you’ve already figured a lot of this stuff out so I may be filling up your PM’s in the future. Need to sell the race car first.

Nice work

Yes, Drive by Wire, used a CTS-V throttle body and pedal. A little bit of a learning curve, but luckily Andrew70 is helping with the tune.

As an update, I got the exhaust welded, and have put about 200 miles on it so far. Still doing some fine tuning, but it's very close.

During the front end alignment, it was determined I can't get the settings I was hoping, so going to switch to offset upper A-arm shafts. That will allow me to add even more caster, which is roughly 4.75 now. If I try to go more, I can't keep the camber in check. Offset shafts will allow me to go to like 5.5-6 degrees of caster, looking forward to that.

I'm using a 2010 vette fan controller, and found out it only supports about 32amp load, so I'm in the process of adding another, and will run each fan on it's own controller.

I have the Billet Specialties billet alt, and, on a drive last week, it quit charging. Did all the typical tests, and it certainly has stopped charging. Luckily, the alt is built by PowerMaster for Billet Specialties, and a quick call has me sending it to them. They say they can turn it around in a day, so by next weekend I should be back on the road.

I have the global West CTA-42A, and need the same ones with the offset shafts. I recall before I was only able to get about 4.5 or so caster, and forgot during the rebuild, or I would have replaced them.

I can swap the shafts on them, but its not a simple task with the del-a-lum bushings.

Here's the vid on YT from Global West on how to install the offset cross shaft in the GW upper arms:

https://www.youtube.com/watch?v=rEkj340Zt7g

I will call tomorrow and see if they offer the arms with the offset shafts already installed, if so, will buy them, and sell this pair which has new ball joints and del-a-lum sleeves.

4.5 of caster is good, you will have a strong centering response with that.

It's good, I drove it like that for years, but the steering wheel wouldn't return coming out of a turn. With the 670 box in there now, it's even a little worse. And the 670 box with a type 2 pump takes more muscle too. I can live with it though.

Pretty sure I can get around 5.5, maybe even 6 with the offset shafts. Not sure I will like that, but I will see.

I did get the second fan controller mounted, it's on the core support and the batt and batt tray hide it all.

Need to pull the rad to split the wires for the fan feeds, that will take me a couple hours, prob do that tomorrow after work.

I should have the alt back Thurs or Fri, and am upgrading/consolidating a few grounds. Going to run a dedicated 2g from batt to frame, up from a 4g, and going to go 4g from frame to block. (up from a 6g). Going to run a 6g from the block to the back of the case of the alt, too.

Pic of the controller add...

I just found your build thread, I had a question. Do you use Dupli-Color Ceramic Ford Semi-Gloss Black Engine Paint? And do you use a dupli color primer before applying the black paint? Thanks

Yes. I use the ford semi on all chassis, pulleys, and those type parts, the 1615 aluminum for intakes, ALTs, and other natural aluminum stuff, and the cast iron one for items like tie rods, centerlink, steering boxes, diff center sections, and so on.

On the castle nuts on suspension and steering, as well as other natural hardware, use the semi-gloss clear after torque so they don't rust. I also hit ARP head studs/nuts/bolts after torque, they too can flash rust. Wiper motor bolts, anodized oil pans, etc.

No primer, I've found that the engine paint doesn't 'bite' as well and can flake on primer. I just make sure it's clean, wipe with acetone, and the typical 3 coats as directed of the engine paint. Lasts forever, and easily can touch it up. I blends well too, you don't have to shoot a whole part or area, just the areas you need.

My one old timer body guys says : 'Yeah, that stuff will stick to anything'.

I did the aerosol truck bedliner too, underside, wheel wells, inside of bumper, it lasts a ling time and doesn't get eaten up by rock shots.

EDIT: After the engine paint cures well, you can polish and wax it.

Got the alt back from PowerMaster, can't praise them enough, the service was incredible. Thank you John is 'returns/tech'.

Put another 200 or so miles on it, the tune is almost complete, just have some shifting programming left, need to soften the 1-2 shift at low throttle.

Ordered the GW control arms with the offset shafts, shafts are getting anodized, they should ship by end of week.

With the GTO endura bumper, the added weight pushed the front springs over the top, and it's sitting too low, and springs are too soft. Ordered some springs from GW when I ordered the upper control arms, but the springs are backlogged to DEC/JAN. Dang. So I ordered some 1/2" pad spacers, which will not only get it off the ground, but also slightly increase the spring rate. I will use those temp until I get the new springs.

Luckily, the springs that are coming out are the exact ones I need for the 442 when I go to the big block, works out for me.

Went back & forth on the trunk tension rods for cars with the wing, have had people debate if it uses a larger diameter rod or not. I couldn't find any larger diameter rods, so I got a aircraft quick release locking pin, and a biker wallet chain, drilled a hole thru the support and trunk arm, and that worked out to my liking. (couple pics)

Still have some minor stuff to do, detailing too, but an enjoying driving it now, so kinda not in too much of a hurry to do stuff!

So had a Moser 12 bolt built for me a few years ago, TruTrac, shortened housing 1/2" on each side, tapered bearings, 373 gears, and alloy axles.

So driving around, started getting some posi-burps around slow turns, and was like, what? No. Really!?! And started thinking to myself, 'What was the ONE thing you didn't go through on this build?' . Yup. The rear.

So then I started thinking, nah, that thing's kind a fresh, it should be good! And then started back-tracking mentally on just how long about I got the rear. Uh. Wow, looks like it might be, um, 2003? 2004? Dang.

Guess I will be rebuilding the rear, like I don't have 50 other projects I need to get done! Heheh!

So grabbed a 20 ton press from harbor freight, sold my old one due to space constraints, cheaper to buy a press than to farm that crap out.

Will get the RaTech pinion depth tool, the RaTech crush sleeve eliminator setup (smart sleeve), and just rebuild that thing. Dam. Really hadn't planned for this, but guess that's the way a hot rodder's life goes!

http://www.ratechmfg.com/pinion%20setting%20tool.htm

http://www.ratechmfg.com/smart%20sleeve.htm

Still need to swap the upper control arms and front springs, charge AC, and a bunch of little stuff, but at least I'm driving it!

I would expect a Moser built rear to last almost forever, how hard did you beat it?

Um. Hard. As much abuse as you can imagine with street tires. But it was like over 4+ engines. A lot of N2O, and think I replaced the ring and pinion once, can't quite recall.

With the 461, it was eating pass axle bearings every 50k miles or so. Housing is straight, it's just that I was pushing it hard. Think it might be the earlier style TruTrac too, which has been updated.

I will go through it, it's time. I can do it for about $1k-$1500 max. Will do u-joints too. It's probably just time.

I will dig out the receipt and check what's in it, and should get an exact date then.

So looked up the receipt for the rear build, it was in '01. It's time.

Cool Spring rate.

"With the GTO endura bumper, the added weight pushed the front springs over the top, and it's sitting too low, and springs are too soft. Ordered some springs from GW when I ordered the upper control arms, but the springs are backlogged to DEC/JAN. Dang.

I'm curious about what springrate you'll end up with.
I've got QA-1's up to 650 lbs./inch.
550's screwed all the way up to the end , just about broke the bumpstop loose 1/4"

I read that you're rebuilding the Moser build rear and I kinda agree with OCMDGTO on that.
These are purpose build rears and you pay for that.
They should last , especially with street rubber.

Well, GW doesn't reveal the spring rates, but I believe the ones I currently have are about 550. The next step up I believe is 620 or 650, but am kind of basing that on previous rates provided by tech support. It's more soft at the moment than I thought it would be, and it contacts the bump stop frequently. I'm tempted to step up 2 rates, but will try the 600s ones first, and if they are too soft, I will put them in the 442.

My 'bird has 720 springs in the front, and under hard driving, it too contacts the bump stops, but it' livable, since it only happens when I really push it.

Don't be afraid to try higher spring rates, even if many say 'it will ride like a truck', it's simply not true. And talk to Doug, let him know what you're experiencing, it will help him zero in on a spring that you will be happy with.

Yeah, '01, that's almost 20 years, stuff doesn't last forever. Like I said, I've had some serious power in front of it, most close to or more than 600hp. The one 400 I had was about 405hp, based on another build I followed, and I was spraying that with a 300hp shot for a while, and dialed it back to about a 250hp shot of N2O.

I get about 100-120k miles out of my engines before I swap them out or rebuild, so it's probably got about 500k miles on it. There was one engine in there, a 455 .060 over, where the crank broke, think that had about 45k miles on it.

I had about 90k on the 461 before I took it off the road for this 'version'. So that too was slightly less than 100k, but that still doesn't drop the potential mile estimate by much.

I had an OE 12 bolt housing for a while in the 90s in this car, that was a brute strength posi unit, and that was professionally built, using heavier springs and vintage NOS asbestos clutch plates. That lasted 10 years, and sold it, pretty sure the guy who bought it is still using it. But he's not making the power I am/was.

I will pull the cover, and look it over, but I'm pretty sure it's going to need a going-thru.
