An old repeat question I'm sure but here goes...
Looking at doing an engine swap in a '79 D150 truck.
The truck currently has a 318 2bbl/4speed man.trans.
I would like to swap in a 360 4bbl and keep the same 4 speed trans. I know on the automatics this will cause driveline vibrations an most of them can be corrected by knocking off some counter balance weights.
Will this work the same way for the 4sp flywheel or do I need a new one specifically for the 360 ?
Also I don't remember which had the counter balance weights,the 318 or the 360...by the way,the 360 will be pulled from auto trans car,anything else to look out for other than oil pan/motor mounts.... Thanks
