305tbi to 383 stroker
OK, I am in the slow process of building my car. I am going to eventually swap out the 305 for a 383 stroker. Right now I am just going to try and do some basic bolt on stuff to my 305, but the stuff I buy I would like to fit on the striker motor. I am going to do an MSD box and get rid of the computer. I am going to have to buy headers, distributed, intake, and carberator to fit the 305 for now......I am going to run her till she blows! But my question is, what can I get that I can use on the 305 as well as the stroker? I don't want to have t rebuy parts if at all possible. The 383 is a crate motor from classic performance and will require the above items when I put it in.
Any help is greatly appreciated!!!

I was going to go ahead and get the dual plain intake and a 750 double pump (and jet it down). I am curious as to headers and distributer. I PM'd Dyno Don about his headers, so I guess I will find out about that interchange anyway...LOL!!!

Changing the jetting does nothing to reduce the airflow (CFM )which is too much for a stock 305 ,
especially with cr*p heads and peanut cam
IF you could spin your 305 to 6K it would only pump 530 CFM (A 350 only pumps 600 CFM @ 6K)
Guaranteed to be a pig
Bad idle , no acceleration and no fuel economy ; sounds like a plan
