hopefully everything will go smooth with the swap. i have the trans removal down to under an hour....i am guessing the engine wont be as easy....i havent removed one from my truck b4.

--should i take the s/c off before i pull the engine?
--also when i reinstall, should i put s/c on b4 or after the engine is in?? i remember one of the bolts in the back of the s/c near the firewall was extremely hard to get to when it went in the first time.....

I would pull the blower first, use a lift plate designed for the ls motors that makes everything a little easier.

where is a good place go get one of those?

is there a fancy do-hickey of a tool that magnuson has for tightening the rear hard-to-reach bolts for doing the installs? or any other tools that can make it easier?

Allen Nelson flogged my setup pretty good. He's tuned more than a few of these. I, as well as many others, trust his tuning acumen. His dyno is pretty stingy though. Not saying that you didn't make these #'s. Just saying the 112 is limited on the larger cubed engines.

Bottom line is that the truck will haul some serious *** regardless of what a dyno says. It just won't build much more than 8psi and won't make the #'s that a larger blower/turbo will. 8psi on a "built" motor is kind of a waste in my book. 10+psi is very livable on a stock 6.0L if the tune is on the money. Forge the pistons, upgrade the rods, and the 6.0 is left breathless with the 112.
