hello I am new here and I have a 1991 Chevy 3/4 ton short box ex cab 4x4 with a 350. I have a 454 that I wantto to put in. It is the same generation EFI engine but have a few questions. 1. Will it bolt up to my overdrive 4L60 transmission? 2. Will I need to beef up the front suspension in order to hold the weight of a big block?
