Title: Wiring ?? 305 to 454 swap
Post by: bfofish on April 20, 2010, 05:41:22 pm

I'm sure this has been covered before,but I can't seem to find it.
I would like to know if all the wiring is the same for the FI motors. Plug and Play or not ?
I am thinking about getting an 1989 FI 454 and turbo 400 for my 87 2wd,it currently has a tired 305.
I know I'll need the computer,but will the rest of the wiring be the same or do I need that too?
