if it were me i would go w/ offenhauser heads about $500, offy intake 200-$300 ?, 2 stromberg 97 carbs or 2 holley 94's, unless the motor will be really bored out and raced then you could go w/ 3 carbs. also fenton headers look nice if you wanna, i've heard that boring out to 3 3/16 is the biggest to go and still safe, but that's just going by what ive heard . other guys here know more about it than i do. aldo you could get a mercury crank and bump your inches up to 255....
