if anyone is running a 440 w/ the mp 292/509 cam i'd like to know your driving experiences.
i'm running a totally rebuilt 440+6, 10:1 , 292/509 , 4 speed & 456 posi. the ignition is the
prestolite dual point unit. EVERYTHING is new & the engine lites right up yet under load
she pulsates terribly throughout the entire rpm range. i've got less than 3 hours on the
engine & gone thru the carbs & distributor over & over yet no improvement. the engine
runs like the firing order is mixed up but that's no the case. i expected some low end
roughness considering the cam but not thru the entire range. any ideas or experiences.
i haven't really dropped the hammer on it to allow break-in but just brought up the rpm's
using the 2 bbl. the engine was professionally built & clearances were checked & re-checked.
at this point i'm ready to pull the covers & intake. the only abberation is some slight tappet
noise but not drastic. is this normal for this cam??? or am i just over cammed
help !
