Im in need of a better intake manifold and cam for my almost stock '65 289. I currently have a Edelbrock Performer intake with a Holley 570 Street Avenger carb.
-What intake and cam should I get?? I want a mild cam. Im trying to get a street/strip daily driver.
You can't beat the older unequal length Ford A321 intake, also the same as the older Edelbrock F4B, Cobra high rise, & Ford C9OX. Keep your cam in the 270-280 degree advertised duration and around a .525 lift. Do not go with a Comp Cams 268H, you might have problems finding gas for it with that one. if your comp ratio is in the 9.0 to 10 to 1 ratio.
If you do anything more than 20-30 minutes of highway driving, I would probably lean towards even taller tires. Like a 255/60/15 (27"). 3500rpm @ 65ish MPH isn't fun for very long.
