Thumbs down K5 LS1 build questions


I'm just starting to rebuild my Blazer from the ground up. I've aquired a LQ4 6.0L from a 2001 Chevy truck and the motor mounts needed. I'm trying to find out if a 4L80 trans will connect to my transfer case or if I'll need to update to a newer one? I could rebuild the 700 in the truck now, but I dont want to spend the money needed to make it safely hold 600hp...Oh yeah, it's gonna be a turbocharged Blazer!

I'm looking at LMC truck for my replacement body panels...anybody have good or bad thoughts on their products?

abig84 will become famous soon enoughabig84 will become famous soon enough

i dont believe so. your transfercase off the 700r4 it will have a 27 spline input where the 4l80 will have a 32 spline output, if you can find a transfercase off a th400 it might fit. kinda hard to say for sure. i been thinking about doing this similar swap in the future

im not 100% if the 4l80 has a 32spline output shaft come to think of it, if you have one sitting around count the splines coming out of it, i have one buried in my garage but been a while since i looked at it. but all the 700r4's ive seen will have the 27spline output
