no, this isn't a buick to chevy engine swap - its a chevy to buick swap. i know you need different motor mounts to go from a 4.3 v-6 to a 5.0 or 5.7 chevy, but will those v-8 engine mounts work with a buick? is the block wider at that area? I would check it out, but b/c it is in a van, it it pretty hard to do a swap, let alone test things - i'm hoping the engine subframe drops like a couple pics i've seen
