Thanks Tom and others

So these obviously dont use a Std RAV bolt pattern for the intake then as there looks to be no material in the flange for an outboard bolt at either end ??

Hmmmmmm........

This picture of the head shows what looks like additional bolts as well as the outboard factory locations

Maybe this is how the TR intake bolts up using these and not the outer factory location

All these intakes will have the stock Pontiac bolt pattern. We are doing the front water neck cross over separately since all our RA-Vs will have reverse cooling. We will also have the ability to use regular flow cooling. More pictures soon.

I took the intake to BES and Tony likes it! We are starting to finish up the first RA-V crate motor in the next couple of weeks.

I still dont see how it can use the "stock Pontiac bolt pattern" outside of the rear runner
Separate water crossover I am OK with and having a "short flange" outboard of the front runners.

From what I have seen with stock RAV intakes 3 of the holes are above the lines of the port with the two outboard ones slightly lower
From the tunnel ram pics it looks like there is no flange in that location. Hence my query about the two extra "non Pontiac" holes lower toward the deck inboard of the outer runners ? These must be redundent or for some other purpose as they arnt in the "stock location" Possibly for a future blower mainifold ??

I would have thought that the TR would have required a longer flange at the rear to pick up the rear factory bolt location (This would typicaly be the same offset from the outer runner at the front to allow heads to be swapped from side to side)

Hopefully I am missing some thing simple here

Lynn, nice article on your 'Crate Engines' in Pontiac Enthusiast magazine.

The mounting holes aren't cast-in, so with enough meat in the head, they can be drilled and tapped anywhere you want them...just a matter of changing the program on the machine.

I see what 455-4+1 is talking about. Using it strictly on an aftermarket head is one thing. Bolt it any way you can or want just so it seals.

But using it on a factory head or with the factory bolt locations is another issue. There is no material for the rear bolt. Based on the picture even the middle bolt would not work.

Exactly, looking at the pics I could not figure out how you plan to secure this intake except maybe 4 bolts per side, two between the front two and rear two runners. No center, no end bolts?

That makes sense i guess. Looking at the picture, is there enough "meat" on the intake to drill it on the end?

Oh, for the love of Christ.

You're comparing a factory intake to Lynn's intake with these pics.

What part about "with enough meat in the head, you can place the intake mounting holes anywhere you want" is so hard to understand?

Want to run a factory intake with Lynn's heads? Drill and tap for the factory intake. Want to run one of Lynn's intakes? Drill and tap for that. That's how I'm perceiving it.

Sorry to be so short...but God damn...this is an aftermarket head Lynn is putting out there to try and fit several different applications...not a direct factory replacement. Same goes for his intake, which he has designed for use on HIS head, not the factory head.
