hi.

Ive been reading alot on my particular swap and here to see if i can get answers to some questions I still have. Also open to any advice.
Here are the details:

Victim.. 93 Chevy SCSB 4.3 TBI AUTO

goal... 5.3(lm7) OR 6.0 (lq4) with the tranny behind it. Drive by cable engines is what i can easily get around this area. (((( NEEDS TO BE SMOG LEGAL))) as i live in california.

i am aware that the fuel tank and all lines associated with evap need to be put in. Also know that i need to wire all cats and sensors for that as well .


questions:

motor mounts(which to use)
driveline(which to use)
wiring(which one u guys used) stock modified or whole new harness. Vats delete???
anything else that I need to know?? lol
