ya this thing is far from being done a cheap way to do a 2wd blazer would be find and old blazer that looks decent and put the body on a 2wd frame I thought of doing the opposit acouple years ago so my truck would be good in the snow but since it has only gotten like 5 miles on it in the past 6 years no point in doing it. but the frame and body will mount up with no problems vins wont match but if its a pleasure ride who gives a shit right? ans the 6.0 with twins would be sick as fuck but these trucks are pretty light in the rear so that thing would be a mofo to keep in a straigt line freeway driveing would be alot of fun but put some weight in the back before I had this truck the guy I got it from had a 525 horse 355 roller motor in it and at 65 on the freeway it would but it sideways when shifting down to pass talk about getting that addrenalin pumpin lol. but as far as drivetrain I and putting a posi in the rear along with 4:11,s that should get it off the line a lil better I dont want to go too extreem on the gears so I can still drive it on the freeway to get to shows and cruises I will get some motor pics up soon
