Will my TPI setup fit on an older 350 block?

Hey guys, I have a '89 Iroc with the 305 tpi. I was wondering if my tpi intake would fit on an older 350sbc. I can get a pretty good deal. And since I have centerbolt heads could I just put them on the 350 and run higher compression?

The block doesn't really care.

You can run your 305 heads on a 350 block. If your 350 has dished pistons, it's a good way to bring the compression back up. If the 350 has flat tops with valve reliefs, you need to watch your CR - might be too high.

the only problem that you will have is the angle of the manifold to head bolts, you may have to "egg" out the bolt holes in the manifold. On my LT1 /TPI, I had to move some of the bolts. Nota big deal.

Just like on the aftermarket intakes that fit both style heads
