Ok........gots myself a 600cfm holley on top a 304 .060 over. So any ways i need to jet the sum bitch down (raw gas smell) but any ways while climbing steep creek banks it cutouts was too often for my liking but the shitty part is that this 600 does not have adjustable floats on it????? It seems all the local FLAPS have 600's with non adjustable floats but all the older ones i encounter have the set screws on the fuel bowls. But im sick of this and the carb is brand new and has only 1500 miles on it and the motor but im out scouting around for something better but not as expensive as a F.I. setup. How does Edelbrocks perform off road and i was checking out this holley 570 CFM street avenger that i think would be perfect for my application since according to Holley's formula i need a 548 cfm carb. I just dont know what to do about this? Buy a better carb or jet and change floats and bowls and make my holley 100 times better???? NEED ANY SORT OF HELP FOR THIS!!! any suggestions will be greatly appreciated!!!!
