Here's an idea.


Since Lynn is selling the crossover as a separate unit, it would probably be mounted like the exhaust crossover on a RA IV intake.

The bolt hole 'A' would have a bolt with a big washer that spans the crossover and the intake flange.

[Tom Vaught]

That will look like H*ll and work like Chit, IMO, John.
Here is why: If you look at Post #107 the bolt hole is centered over the water cross-over water passage.

You put a big washer on the boss on the water cross-over and all it will do is act like a diving board out on the ends unless it is very thick. Either way it will look like a band-aid for a screw-up.

Does raise some questions about the front runner / crossover mount also as mentioned ??

The hole I identified as "A" was at the rear in this pic, (note Dissy hole) the water hole here would usually either be a heater nipple, freeze plug or aftermarket "rear crossover deal".

I can almost understand no flange at the front (I have had separate crossovers on all of my engines, makes good sense), just not the rear ??

Interesting idea though, connect the banks at the rear and run a single line to the front crossover under the intake.

Also with the thickness of the intake runners, dont think there would be any kind of warpage. Looks like it would bolt down pretty tight.

If Lynn was able to get the project to this stage I doubt he's not thought about how the parts are going to be bolted together. He'll probably be along shortly to explain how he's got it all figured out as soon as he quits laughing at all the others trying to second guess his engineering plans.......................

He doesn't seem like the baling wire and bubble gum type of guy, at least not to me. Just be patient, as Rome wasn't built in a day neither is a resurrected new and improved Ram Air V engine program. This was a huge undertaking for Pontiac to do with all of the resources they had and Lynn is doing it with only his own resources and a few select peoples help. The magnitude of this type of undertaking is pretty amazing and he's doing a great job so far in my opinion.

This project is right up there with what Indian Adventures did with the IA1 block, it's a good thing Pontiac guys aren't quitters or we'd all have 068 cams and D port heads cast iron manifolds with Q Jets......LOL.

[Tom Vaught]

No one has yet to prove that the intake will not clamp down as cast.

The question was: "Will it seal on a production V head", (basically).

That remains to be seen, so why don't we have a bit of patience on the deal and see how the dyno testing goes.

Sorry guys I have been busy and have had limited computer access. There is a rear bolt hole for all intakes, this pictured intake was a prototype intake that was changed. (Isnt that why we do prototyping?) Our tooling guy assures us it isnt required for this intake, but put it in there anyway.

As you can see with the picture of the RA-V head picture, RA-Vs intake bolts are different. They have no bolt hole in front of the front intake port like a traditional Pontiac(Ports too big). I have asked my tooling guy to add as much material to the front in that area to run a small bolt into the head if they wish to add one themselves. Yes we previously added two extra bolt holes to the center area if so desired.

Cross overs will be separate. This allows us to do the Reverse Cooling or traditional Pontiac cooling as our customers wish. It also allows flexibility of using a stock intake on our heads.

We have done as much as we can to make these interchangeable with the OEM stuff as possible while also adding the new technology to the new head(raising the ports). We aren't perfect and we appreciate everyone's input. It keeps us on our toes!

All questions and points appreciated!

[NHRASuperStock455SD]

What do you guys think of an exhaust manifold set that are tubular? They would be about the same size as the factory exhaust only with optional collectors flanged or with the new style connectons? We are definitely doing them, and need your input.

We did a prototypen for a car my son is working with Turbo pipes included. I can post pictures next few days.

[tom s]

Lynn,I think virtually anything that will fit GTOs and Gen !! birds would work.A good pattern would be the tubular ones made for the 63 Tempests and the NASCAR big cars.Almost like a shorty header.Tom

[Dragncar]

Just keep it up Lynn, when are we going to see the results of all your hard work with numbers.
I want to see what these heads can do with a IA2 or MR1 on pump gas.
If we only had people at Pontiac like you when it all went away maybe it would never have all went away.
The effort that has been put into this, and the people chirping that it would never happen, or the peoples money is gone, with where its stands right now, has got to feel good.
Thanks, its mind boggling if you think about it.
Takes a crazy person.
Or a real honest to goodness Pontiac person who put their money where their heart is.

[1971WARBIRD]

yes.they were on the tailgate of his trailer when i saw them.2 heads and the proto intake.when do they do the lottery drawings???

[tom s]

Jerry,he had one head at Chris Schneck(spelling)rig and others at his trailer.He was to have my two sets and Chris there but I guess the seats did not show up on time.Hope they get done this week.Tom

[spartazoo]

Oh yeah I saw them... All I could think about was baseballs.

Awesome hardware!

[Region Warrior]

Good see'n ya again Lynn.
As aways, very interesting, and not enough.
The design looks great imo. Dont think there'd be an issue the way you explained it.

Shame you wernt able to take the RAV bird out.
Next time, CALL ME when you need help!

Once i decide on crank stroke, give ya a call to send $ to get started.
Stock style intake with removable top for either Q-jet or dominator???
Dual Q-jets would be awesome, but the n2o set up would be a headache.
Remember, try'n to keep everything under stock 68 FB hood
Wel also decide on 2" or larger primaries once you get header production go'n.

[NHRASuperStock455SD]

I had so much of a blast talking to the Pontiac guys I couldnt even get my car ready. Oh well we ran Stacy's car, but he had two terrible leaves during the heads up race.

I tried to explain to everyone the difference between the show models and the updated production models not at the show. The main difference was mainly the Tony Bischoff influence.

One that everyone needs to know......these heads have been significantly improved for street use with smaller ports. All stock parameters remain. The only thing really required is port matching if you are swapping OEM to McCarty Racing. You can even run the stock stud mounted rockers.

[tom s]

hard to get READY when you get there a DAY late!LOL,Tom

Well Tom, at most races they have VP racing fuel so we had to track down a dealer in Toledo and buy fuel for several people screaming bloody murder. Of course our special cause occurrence of a blow out on the MH didnt help much either. We didnt plan on being there much on Friday anyway. We were there all friday night all day/night SAT and all day SUN to the very last trailers. So...I think we made a good showing. Most response was favorable. We will simply never wait in Linder's lot just to get into the track. Especially when we must pay employees to run the shop while we are gone. The other end of the track is fine. The guys who really wanted to see us....saw us. Appreciated the opportunity to participate.

[tom s]

cant thank you guys enough!Hope you got round money!Was great seeing the S/S car run.NO ONE could believe the car was running a QJ.Just goes to show how hard you guys work to make those cars competetive with the other makes.Tom

[Jim Robertson]

Good to meet you Lynn and Stacy and discuss the very nice hardware. Looking forward to getting a few sets in here to work on. Did the heads go out on Tuesday as discussed? What's the schedule for the single 4 intake?
