My fiance' absolutely loves the 3.8 98 monte carlo i bought her. Now here's my issue...she wants it v8. I looked into a rwd conversion, and having her car tied up in my shop for about a year while a 427 ( her favorite V8 ) is fitted is unacceptable to her and cost prohibitive for my business. However...i looked at the 5.3l V8 that GM has in the 2006 and up w bodies. Definitely the better option and fairly low cost. But...has anyone ever messed around with this and how much effort is involved. I'm able to swap with no problem on fabrications. Where i'm a little leary is the electrical and body. Plus i don't really want a used engine. Where can i get a 5.3 FWD new and where do i need to work with the body?
