I have a 89 Tpi set up and I'm going to get a 85 or 86 intake so it will bolt up to my stock heads and I need to know if the runners and every thing else will bolt up the same.
it should as long as the 89 setup is a MAF setup which it should be.
You know you can have the 89 manifold machined out to fit your 85 style heads. I reamed mine out with an air grinder with a drill bit in it. It was a PITA but I got it done and it is working fine.
A cylinder head shop or machine shop can probably redrill those holes pretty easily and cheaply.
You have to take quite a bit of meat out of the manifold and open the holes up to the proper angle. there is nothing really special about it, grind it out alot then try to fit it. If it doesn't fit pull it off and grind it out some more.
I would call a local cylinder head shop and see how much they would charge to ream out the holes.
I have everything to do it i was thinking it might be easier to find a older manifold may be I'll give it a try and if i screw it up then I'll get the older one
Whatever you wish to do. I live near Decoto/Paseo Padre in Fremont so if you decide to meet up I am sure you aren't too far away. /forums/images/graemlins/thumb.gif
$40 is TOTALLY worth it. If I had it to do over I would fork of the $40 to have it reamed out. It was a huge PITA. I didn't know that at the time so I learned the hard way.

$40 might be worth it sence I haven't done one yet and GM sport wants $125 for the manifold, I contact you about it.

WHAT they told me less then that.
Anyway, I had to do this to my manifold. Im in Castro Valley, if you want you can borrow my burr to open the holes and cut the angles into it its a piece of cake, also, you can check out my manifold too if you want. Let me know.

Who told you less than that? Are you talking about GM sport salvage about the $125.00 manifold or are you talking about me giving a lower price to have the manifold machined?

I don't think GM sports sells anything for less than $100.00, kinda like a Harley Davidson, HD = Hundred Dollars /forums/images/graemlins/rotfl.gif

HAHA /forums/images/graemlins/rotfl.gif No kidding. I asked them about a TPI setup , they wanted 650, OUCH!
