critical Clearances
these clearances were obtained with engine sitting in frame
1/2" forward of original engine position measured from block / bell housing joint
offset in mounting bracket from four mounts that hold bracket to engine is 9/16" down ( ie engine lifted up )
measured form center line of top two mounting holes
I will post a drawing soon.
bracket made from 5/8" material using an Mackay mounts part no. A1128
Note i found that the Mackay mount measures close to 1 1/8" think where the US mounts I have measure 3/4" thick
the engine could be set up lower in the frame
but where I have this now the oil pan of the 4L60E is at the same level got ground clearance as the oil pan for a BB engine
clearance full right hand steer
clearance full Left hand steer
clearance alternator to engine mount
clearance under mounting
transmission / chassis
