  • As with any build, I have had a general idea of what I was going to do. I had the original TH350 & NP205 & a 350 crate engine with only 15K miles on it but the 6.0L came with 81K miles & a matched 2WD 4L60E for a deal I couldn't refuse so the 350 is coming out. I will have to do some machine work to the GM adapter to match the 205 to the now rebuilt 4L60E with an Advanced Adapters output shaft...5 transmissions in the shop & not one really does it for the Blazer. I have the gearvenders over/under but the wheel base may be to short to use it.
