iight at the moment i got the origional 305 in my 84' z28, im going to buy a 350 with a tuned port injection, i wanted to kno if i get the 350 and i bore it out to a 383 will i need to change any electronics to make it pop in more fuel for the larger piston size,and if i get the fuel lines from a 89' iroc-z will they pop into place with my 84 gas tank, also with the 350 wire harness are they the same plugs for the dash and lights and all that or will i need to pull them out of an iroc as well.

pretty much wat are the parts you recomend i grab wen i pull the 350 tpi
