Yes.
But you'll have to oval some of the holes in the intake manifold to make it bolt to the heads on your old 350 block.

Re: TPI INTAKE
They will fit fine if you use the heads that are in the car now.

Re: TPI INTAKE
Yeah I would definitely switch to a set of 083 heads... But he has the 081s... which may or may not be a good compression range for a 350... but the stock tune isnt gonna work with a 350 anyway.
But yeah, the TPI will bolt up aside from a few intake bolts that are a different angle. I'd consider doing a head swap on that 350 to a set of 083 (TPI Iron L98 heads) heads and trying to find a stock 350 ECM. You'll need a new knock sensor also, and I think there's one other thing you need...
But your TPI system is Speed Density, so you dont have a MAF to help with a tune mismatch. But if you go with stock parts, the tune from a 350 should work.
