Faster? It would totally depend on the engine. You cant just throw a 350 against a 305 without some details of the engines. But ifI were you I would go with the 350TBI, it just has more potential, and it's easier to modify.

I have an '85 IROC with a 305 TPI and a '92 Astro van with a 350 TBI.

The IROC is the biggest pain in the a$$ to do ANYTHING to. If you ever want to put heads or a cam on a TPI engine plan on spending another 3 zillion dollars for a ported base and runners.

I loathe torx bolts now.

each to his own...just my $.02.
