I am thinkin about pepin' up the engine alttle. My current cam specs are
-duration of 292in &300ex...Valve lift in. is .528 &.533 ex. @ 1.76 RR(dont no what the means) Valves are2.25/1.75. Could i go w/a slightly larger cam w/o changing springs and other valve train componants ? I am swaping out my old 4160 carb for a new demon w/o choke. Engine is a SA 66' 427 so.w/10.1 pistons and a 4.125 stroke. Maybe a nice custom cam from KC would help...
I figured some manufacters mite just say ,"go ahead,it should be ok" Where as someone here mite have done this allready and it worked out fine.
