holley Jetting
got my engine together and running , 472 cadillac alum heads single plane intake 850 double pumper cam etc running 80s in the front and 90s in the rear. Very rich to the point that the engine misfires and flames out of the pipes needs to be leaned out for shure, any suggestions what i should start with, holley standard jetting is 80s on both ends, thinking of dropping to a 78 in the front and 82 in the back.
Any ideas for jetting idles great and can adjust easliy with screws i would think comparableto a 496 with 300 cfm heads
anybody ruunning a big block and know what jets they have, I need to start somewhere and i know i need to go down not up.Last edited by canadianal; 04-01-2011 at 09:02 PM.
