I am hoping you can take time out your busy life and share your knowledge. I am working on a 1974 Chevy Camaro 250 stock machined 4.1 engine, going into a 1960 Chevy Impala with a 200r4 trans.
What upgrades would you advise for this engine. Dual exhaust,2 barrel carb. etc. I have a H.E.I dist. already. Also what rear end gears? Thank You and hope I did not ask too many question, again Thank you Sir


the 200r4 trans is a great upgrade,
ID suggest a 3" single exhaust or dual 2.5" and headers if you can find them, obviously the exhaust must match the headers

or you could fabricate a custom built set.
or modify a set of headers for a truck,

ID also have suggested a 450 cfm 4 barrel and matched intake if it was my car.


that 6 cylinder will not want to spin much over 5000 rpm, so ID suggest a 3.43:1-3.54:1-3.73:1 rear gear differential if you can find one
one more reason owning , and knowing how to use,a decent welder is a great idea
