Gen 3 Hemi Crate Engines (5.7L, 6.1L, 6.4L) / 62-65 B-body applications with spool mounts: From the center of the crankshaft to the top of the K-frame, the correct distance is 6-3/8" (to be determined). 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" (to be determined).
63-66 "A"-body applications: From the center of the crankshaft to the top of the K-frame, the correct distance is 4-3/4”. The engine is also offset 5/8" towards the passenger-side. Measure from the center of the crankshaft to each frame rail, the difference should be 1-1/4”.
62-65 "B"-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 3”.
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”.
65-73 "C"-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 3-1/2”.
gines (5.7L, 6.1L, 6.4L) / 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 5-5/8” for A-bodies (5-7/8” with spool mounts) and 5-3/8” for B&E-bodies (6” with spool mounts). The engine is also offset towards the passenger-side. Measure from the center of the crankshaft to each frame rail, the difference should be 3-1/4” for A-bodies (2-3/8” with spool mounts) and 2-1/2” for B&E-bodies
