M1, Victor340, and RPM Air Gap flow testing

Question, I'm helping a buddy build a 360 for his Scamp. .030, 9.8-1, ported 308 heads, bowls are done and an intake gasket match-1.94 and 1.625 +.100 GM valves, (no numbers yet, but I'm sure some of you guy's have an idea on flow), 254-259 @.050-.520 Racer Brown cam, Hooker 5204 1-3/4" headers. We are looking to use an RPM (not air gap) because thats what he has and we are going to start with a 750 Holley. Should we use this intake or look for something else? The rest of the drivetrain is: 3800 Dynamic , 727, 3.89 9" and whatever tire we can fit on it. If we can get him to 11.99, he will be very happy. Thanks, Gene.


I’m a firm believer that on builds like this use what you have and have fun with it. Sounds like a bunch of parts that will play well together. Gasket match the intake to the heads and look into the plenum to see if anything needs a quick clean up. Rule number one is stick to the budget you can afford. Rule number two is go out and have fun. Set the timing within reason (32-34 total) and don’t rev it to the moon.
