Dude just do it. Keep the 350 in it until you get the motor built the way you want it.
Nice to hear man, there are good deals out there! I saw a S14 shell for $500 awhile back!
I’d like to Detroit diesel swap a chevy 3500 dually, mid-late '90s probably, and drop the shit out of it. It would make a nasty tow rig :excited
