I have a 1969 383 with 10:1 CR, 452 heads, and a 600CFM carb. The bigger summit cam and headers.

Not counting weight..is there any performance to be had with going to a Ebrock RPM or other after market intake? From what i read the stock intake isnt all that bad.

thanks.



Really , where did you read that ??? If you look at the dyno test fast68plymouth did on his 383 the stock intake leaves about 40HP on the table vs. the RPM , no other changes .
