pontiac intake mod, 65 and up to fit 61-64

is there a mod to fit a Pontiac 65-up intake and after market ones to fit and work on 61-64 heads, not having any luck finding the right intake, really just curious the real differences between them and why they aren't compatible
I do eventually want to make my own custom intake but that's much down the road

also my first thread on here

 

Should have used your 1st post as an intro..
I'm curious also... So, here's a bump for ya!...

 

Try these guys, lots of great Pontiac tech over there. Hit the search ****on and you might find what you are looking for.

Good luck, -Abone.

 

Use a set of '65-up heads and it should work. It would be the easiest solution.

 

thanks guys ill research further into this, and I I recently found a 64 grand prix that's been sitting for decades, its a rust ball but it might have some goodies left on it,looked like it still had the engine( might go for the whole engine if its a SD 4boltmain ), the guy might not let me near it haha but I will find out soon, if that's a no go ill try to get some heads

I do plan on getting newer heads especially since what iv found out mine are 8.6 or 7.6 to 1 compression but when I do I will take measurements and post the differences between them

 

You may as well get the whole car and part it out. While the trans is probably ****, the '64 blocks have the ear for a block mount starter like '65 up and the bolt pattern is close, if not the same. (some have just an ear, some have holes, some are even tapped).

I parted one out a few years ago and did pretty good on it, but I bought it right (s**** price).

 

The pre 65 intake covers some water ports at the rear of the heads and the bolt pattern differs at the water crossover at the front.
I cant remember for sure but I think the rest of bolt pattern is the same.
　
Pre 65 intakes are very common at swap meets …. most people want 65 up
