More power

[Quilly Cochran]

How can I get more power out of my 355 sbc I have a 750 Holley double pump carb the stall is like 19-2100..I recently bought a bigger fuel pump Holley and a MSD-85551 Distributor, Pro-Billet, Magnetic to match the msd box I got I’m looking to put it on this weekend..I need answers !!!

first thing is to get a smaller carb, a 500 cfm Holley will work great on that engine

But seriously what cam are you running? Might be able bump up on that but it may not be a quick addition. I agree with pontiacgp on the carb.

What's your rear gear ratio?

More camshaft - What's your expectations?? Your cam, heads, intake, carb, convertor, and gear all have to complement each other. With 310 HP you have the power to get into the 12's
