What kind of problems will I run into swapping an LS motor into a 93 LT1 car ? I plan on using a FAST engine management system, LT headers . The car now has a TH 350 trans and tubular Arm K member (not sure of mfg).

You will have to swap transmissions or get an adapter for the TH 350 to work. Engine mounts are different. Maybe some fuel pump changes.

Here ya go:
