I have a merc 410 in my 71 pickup. I am currently running an edelbrock performer intake, mild cam, headers and 2 1/2" exh, edel 750 carb, and c8ae-h heads. I am wondering if I would notice any gains by moving to a edel perf RPM intake. I do live in a relatively cold environment, would the lack of exhaust cross over hurt me too badly after warm up.
thanks,
kapp
