Re: big block chevy 402
the 71 402 in my cousin's 66 Chevelle 300 deluxe ran pretty damn good- and he didn't have a ton of money in it, either.
just a stock rebuild with a mild cam and a Performer RPM intake with a 3310 carb, headers, and cheap 2.5" dual exhaust with glasspacks. with the 3.31 gears and a TH350, it ran hard and got decent mileage.
you don't plan sincerity.
you have to make it up on the spot.
wanna hear about 20 years ago when i was too smart to know any better?
