Performance parts that fit 305 and 350?
 

I'm wondering if there are any performance parts that I could buy for my 305 that would transfer over to a 350 tpi if/when the day comes for me to upgrade? It sounds like aftermarket runners fit both, but would it even be worth it on a stock 305? What about a ported plenum? Anything else?

Fuel pump,
headers/exhaust - careful here, or you could reduce 305 torque.
intakes and TPI setup and other things that let it breath
all tranny mods
