my friend just got done building a 57 chevy nomad drag car for a guy. 454 with a nice cam and heads around 800hp. the owner put a 950 carb on it. but my friend thinks a 750 would work best. they run a 600 holley on there 350 that runs 6.30's at sunshine. but they are chevy engines.
for some odd reason amc likes big carb's. you can put a 750 holley on a stock amc 360 and get better 1/4 times over a 600 carb

i don't know about's old's
ps: i'm only putting a 750 on the motor in my sig. it's a 401 ci
