just removed a very tired 305 from my 84 blazer. Putting a 350 crate engine in its place. My question is about motor mounts. Should i purchase nw motor mounts when i swap engines. The ones i have look pretty good. if you guys think I should what is the advantage. who sells the best engine mounts. Any information that you could provide will be greatly appreciated. I'm kind of a rookie when it comes to this stuff.
