bought a 90 350 corvette 350 short block it has 49k on it and just had a gm performance roller cam. i'm thinking i should keep the bottom end the way it is, maybe swap the cam out for something more heavy cause the one in there is a mild street cam. it has a high flow oil pump on it too.
thats the bottom end

HEAD: now it doesn't have heads so i am open to ideas should i put my 305 heads on it, i don't really want to. i'm looking to make 350-400 h/p but i don't see it happening with the tpi setup. should i go with vortec heads or a lt1 top end? so many ideas just looking for a real good street setup that i can do a lil racing on the weekend.

my 305 distributer and everything swaps right over correct?

i thought about swapping the tpi over but just porting the hell out of it until i get the money for something better and get a corvette eprom, will i need to change any other wiring or anything?

i wanna get this done by june so i can get the car ready for the woodward dream cruise
