440 Motor Mount Measurements
67-76 "A"-body / 66-74 "B"-body / 70-74 "E"-body applications: From the center of the crankshaft to the top of the K-frame, the correct distance is 5-1/4”. The engine is also offset towards the passenger-side. Measure from the center of the crankshaft to each frame rail. The difference should be 2-1/2”.
I am sitting between 5"-5 1/4". Frame rail measures at 13.75" passenger side and 16.25" driver side. A 2.5" difference.
