440-6 hesitation from idle? - 02/02/12 04:11 AM
10:1 compression, Lunati 60303, alum heads, stock manifolds, auto, new 71 repro carbs (6.5PV, #65 jets, #35 squirter, with blue cam), 18deg base timing, 14in vacuum @ idle. Engine starts and idles fine, though rich as center partially on the idle transition circuit. Idle originally 12.8 on AF meter. Widened the outboard plate holes 2 drill# sizes, from .082 to .089, which improved AF to 13.5, still a bit rich. Still debating whether to drill center plate or continue drilling outboards or ???
Noticeable hesitation when revving from idle in park (car not on the road yet).
