350-454 engine swap
 

hello I am new here and I have a 1991 Chevy 3/4 ton short box ex cab 4x4with a 350. I have a 454 that Iwantto 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?

any help would be appreciated. Thanks a lot.
