So in the vain of returning it to the CHOOSEN love. You may only rent the HO T/A.

Yes Mr. Weymouth !

Here's what the Melling SPC7 cam sounds like (with NGK spark plugs):

The plugs make a heck of difference in idle quality.

Thanks for the Mellings P/N,Lloyd.

Should I be buying their lifters,as well?

Seem to recall hearing that there were some poor quality (stock type) lifters being sold a few years back.

Anybody bought any recently? If so,who's brand & how did they work?

Enjoyed your video/sound clips, njsteve. (the engine annalizer is GREAT!)

Also,gotta love that SOLID STEADY 20" of vacuum!

Are you telling us that your HO liked the AC's BETTER than the "chinese" plugs?

I am assuming that your HO is still stock compression?

Is that a Gardner exhaust system we're hearing?

[njsteve]

The engine is stock compression with uncut 7F6 heads. It does have forged .040 TRW pistons, Cat forged rods and an Eagle crank. The pistons were in the engine when I took it apart but it needed a new crank as it was cut already .010 and .030 and had badly scored bearings from dirty oil. I like the forged rods for insurance reasons since this is the original, born-with engine from the car.

Actually, it loves the NGKs and the car idled much better with them. The Delcos were just as new but the engine idled much rougher with the factory Delcos installed. You can see how, in the second video, the engine almost dies after being started with just the key and no gas pedal. In the first video (with the NGKs) the engine immediately started and maintained the same idle. I have put the NGKs in everything else I have and noticed the same improvement in idle quality. My old 1970 hemi liked them especially.

That is the Gardner exhaust. Great system if you want an exact duplicate of the original. If you are going for originality that is the system to buy. If you are going for speed, the Pypes system is the one to get. The installation on the Gardner was amazing: everything just slipped into place in the EXACT position it was supposed to go in, no adjustments, no cutting, no "massaging". It just fit right.

I love the old sun machine. I was trained on it as a kid and found this one for $100 at a local Chrysler dealer in town. It was sitting the back room. I've already tuned up all my other old cars on it. You can shut down individual cylinders to see which has a fouled plug or burnt plug wire, etc. It's sure fun to play with!

[1971455HO]

I have a couple of three or four questions for those of you that are far more experienced than me. I have had my engine, for the most part, assembled and buttoned up for some time now. By buttoned up, I mean, the whole spinning assembly including a BOP neoprene rear seal installed, everything properly torqued and covered with the pan. New, hydraulic Comp Cams RA IV "T" camshaft, lifters, stock length pushrods and 1.5 roller tip rockers. Heads were freshened up and new stainless exhaust valves installed. Heads had previously been cut and calculated to bring C.R. up to 8.92:1 with .030" overbore, mild bowl porting, three angle and back cut to improve flow. Heads are torqued and valves adjusted to zero lash + 1/4 turn using BB Chevy studs. Valve covers, Valley pan, Distributor, Intake, Carburetor and Timing Cover are just loosely bolted and/or sitting in place to protect internals from dust and debris. I said all that to ask the following. 1. How often, if at all, should I remove the plugs, squirt some oil in the cylinders and rotate the engine? 2. Should I reuse my Cloyes timing set, 10 yrs old, but only 5,000 miles on it, not sure if it has to much slack on it or not? I don't know how to judge what is too much. It is certainly looser than a new one. It has about thirty 1/8 mile passes from the dragstrip and the rest are street miles. 3. Should I replace the wear washer between the block and the cam gear? I can see and feel the wear grooves in it. I don't know if I need one or not, this one has lasted 38 years. Where can I get a quality replacement if needed. I don't want to trust a cheap Japanese built replacement part from some auto parts store or restoration dealer. Tell me if I'm being anal about this, I've just never replaced one. There may be no harm in an aftermarket one, I don't know. I know i don't want metal in the oil pan. I apologize to everyone for making such a long post, but I just need a little help from some of you guys.

P.S. I would love to own an old Sun Machine also. I've saw a few. They wanted $400 for them though. I know they cost a lot more back then, but nobody wants them but us now.

Thanks, Eddie

[300 H&H]

Eddie,

It depends alot on your climate, or should I say your engines climate. If it is in an unheated area, with a place that gets winter I would shoot some oil in the bores every 6 months, or before summer and winter, as condensation can develope. I don't think I would worry to much about the Cloye's timing chain as long as it is reasonably tight, should be good for much longer. But it is not that expensive to replace either..... The cam gear washer I would be a hunting NOS part for, as I am with you on the import stuff. Unless you have a metalurgist/tool and die guy to help you determine the "good stuff". JMHO. Best reguards, Kirk

[300 H&H]

I am seriously considering going to Stanton Michigan for the pure stock drags on Sept 12th & 13th. I did the map quest and a search of the lodging in the area. I am wondering if there is a hotel that is close to the track, that is a popular with the "car crowd" Just need some inside info to help with the choice a bit. Thanks, Kirk

P.S. I really want to see an H.O. car whoop-up on and S.D.......not to mention others...

I don't think the SD guys actually RACE their cars.
They just leave them "chained to the trailers".
It's kind of a "display ONLY" thing.

[Mark Weymouth]

Kirk, go to www.geocities.com/psmcdr/

It will have hotel info for you. BTW I just checked to make sure the sight address was correct and Dan has change the site cover car to my Hemi Challenger doing a big burnout. Dan never told me he did that. It is an original 15K mile car that was doing a special magazine shootout against a '67 427 Vette that year. It was called the Virgin Stock Shootout. Both cars had to be 100% original right down to the jetting and factory timing curves. Mine was still running its original factory exhaust even. The Hemi won! Love the burnout.

Now that is how to treat these cars. It is a Mopar Nat class and Senior winner, two Concours wins, Carsisle winner, Mopar at the Strip winner etc. And I raced the heck out of it. For safety reasons I did take the original tires off it for the race.

LMAO! That ought to get a nice, spirited debate started!! I think I'll copy that over to the SD forum just to give me some online entertainment tonight.

Mark,
That's what I like about you and your cars! You love to drive them and enjoy them and I do too! I love the burn out with the Hemi - that's awesome!

Here's mine going against my G8 at Commerce. My oldest son and I had a blast that night.

I think that would be a GREAT IDEA!

Invite them to bring their cars over here.
I've got some bolt cutters to get them chains off & I'll bet with some fresh gas in the tank,we could even get some of them RUNNING!

DUDE! I read your post over there.

That's pretty HARSH!

Tell them not to forget their timeslips.

[superdutybob]

Sorry I didn't see the post soon enough to respond. I was out in the garage waxing and prepping for the next show. You know, greasing the trailer bearings, checking lug nut torques, etc, etc.

When a car like the SD is at the top of the value food chain, it needs to be taken care of and pampered. HO's are a dime a dozen. Break one and you go out and get another. LOL

[300 H&H]

Bob,


You mean you can break an SD? with all those special HD parts I "thought" they are supposed to be unbreakable! Not to mention that they seem not to be at the "top of the food chain" in pure stock racing. Kirk

[superdutybob]

I said "value" food chain!

[Mark Weymouth]

Super Duty Bob I think the HO contestants can beat you on the "value food chain" also. HO's are a better value and B last time I checked 455 HO Judge Converts are clearly trumping SD's in value by double. Not to mention regular Judge HO's do not come cheaply either. Mr. Christenholz and others can explain if need be.

Secondly RA IV cars trump SD's in value also. Plus any RA IV T/A makes your SD's look rather common place.

Now to defend the honor as it is of our fellow Pontiac lovers that just so happen to "not" drive SD's... Mr. Paul Aragona regularly thrashes his SD in front of PS fans several times a year. And on Tuesday I will have Mr. Aragona's new SD motor on the dyno with Dan. SD lovers rejoice as we left little to be had in this build. If an honest SD has a chance at chasing a HO down the track from closer than a ZIP code away it will be this one I hope.

TypicHOl Mark

[Judge273]

The best thing Pontiac did was supply the thristy roundport fans plenty of variety. Also, keeping them very exclusive, and in some cases within reach. I have to agree it a a healthy roundport family, and still a collectors dream engine depending on your taste.

To start the dragracing musclecar roundport craze with the FB, GTO in vert and ht with the RA II for 68, and next year offer a FB, TA, GTO, Judge with the RA IV. Even with the rare verts for FB, GTO, and Judge only. Then in 70 offering the RA IV in TA, GTO, and Judge only with a again a few verts in GTO's an Judges. Then in 71 offering a full menu with LeMans, T-37, GT-37, GTO, Judge, Formulas, and all TA's with the 455 HO. With a LeMans, GTO, and Judge in rare vert form. Then they started to scale back in 72 offering the 455 HO again in all TA, some Formulas, and LeMans both HT and verts, and only in HT GTOs. Lastly, closing the craze with the SD TA, and Formulas for 73 and 74 as the last hoo-rah.

Which is the best? Who cares? If you got one drive it!

[Mark Weymouth]

Just so everyone knows I was just being playful above and having good fun with all sides of the play.

I sure wish I could one of each but reality dictates otherwise.

We will keep everyone updated on how the SD dyno's. Wish us luck as Paul sure puts his heart into that SD.
