Got the "77" running fine, but had a vibration in it even in park or neutral. Tranny was bad so had it rebuilt w/ new flywheel, torque converter. Still has the vibration, not quite as bad, but gets worse under load. We'll check the motor mounts tomorrow. Looking for other things to check. Engine is of unknown pedigree, appears to be "86" 5.0 w/ Holley 4160 and HB part# matches up to that year. Very few miles on it, but internals are unknown. How can I tell if the HB is good or not? Any suggestions appreciated. A guy over on FTE has same problem, but no solution yet.
