i wouldnt man...i did the same thing cuz clifford told me i was gonna need a 390cfm. they said i might "wash" the cylinder walls with fuel...so i bought a new one $450!!!! what a load of crap...it ran so rich! basically the thing wouldnt flow the air it needed...so i slapped a stock holley 600 on there and it was perfect! ran great and put down 170hp/300tq at tires. i think we did go back and drop a jet size on the 600 tho.
im telling ya...dont waste time with a 390!!! get a more common on the shelf carb 600 or less and be done
