I'm rebuilding a 70 340 w 4 barrel (J heads / forged crank) back to "close as possible" to original specs for a 71 cuda.
Of course slight boring will be done to get cylinders round again, but I want it to be just like the day it was built.
? does anyone have info for the 340 (4 barrel "shaker" LA engine) original cam specs.?
(duration, lift, center line, overlap etc.)
