So last season I installed a new edelbrock 750 cfm carb and I was just doing some reading on what jets it has stock for the secondary...0.107


I have a tuning kit for this carb and was wondering what would be the difference if I went up 2 stages to 0.113??? would it give the engine more power,,,,more fuel...more power???

Not if it doesn't need it. How does it run now?

with a mild 455 it should be pretty good on seconday jets. I would paly with the power piston springs and rods. the stock spring is too low vacume for a mild set up . they are ok for a street carb . problem with big cube engines the secondarys open too fast and make a lean stumble when nailing it.

My old 650 edel had the orange springs on the primary's .... I wonder who wonder what is the stock primary spring on the 750
