Jun 07, 2007 · I have a 1985 Chevy 350 with Edelbrock 600 cfm carb and RPM performer intake, and a crane cam. I developed a miss only at low RPM's in cylinders 2-8 a few weeks into break in period on newly rebuilt motor. I replaced rotor, cap, button, coil, ignition module, spark plug wires, and spark plugs. Motor appears to have good compression.
