hi everyone, i recently blew the head gasket on my 85 tuned port 305 trans am. naturally i went out and bought a 400 soon after, knowing my 305 will serve a much better purpus as a paperweight.

so heres my plan:
rebuild block
port 400 heads, tripple cut valve job
port lower intake for tpi
roller tip rockers
headers and "free flow" 3" exhaust
http://www.compperformancegroupstore...ode=CL12-366-4 <- this camshaft
leave stock 305 tune

now i have read on here that a 400 works well with a stock 305 tune, as long as the injectors are replaced from 19lb to 24 lb. but this was with a stock 400, since this will be slightly warmed over, should i use a 27 or 30 lb injector? oh, and i am also changing my transmission from the stock 700r4 to a world class t5. any suggestions or commentary welcome, just looking for good advice on this build.
thanks!

Exactly why would you invest that much time, effort and money and then not get it tuned?

The reason for a stock tune would be that i have the 85 ecm, which would have to be spliced over to an 86 or newer to be tuned, then i need a tuner and a dyno so im looking at at least a thousand more dollars to do all that. Not easy with a minumum wage job. I just need it to work, and then later i can work on making it work better, once i have some cash to throw around. The car was my daily driver

Calll Wongs performance (google it) bet it doesnt cost anywhere near that.

Youll smoke that new motor without a proper tune right off the bat.
He can get you pretty close without the dyno at least where youre safe.
