Swapping a ls1 into my 95 c2500. I'm re using the original nv4500 transmission. The ls1 has a flywheel and clutch off a 2001 6.0. When I mount the trans up the throw out bearing isn't even close to engaging the pressure plate....I'm lost. Do I need a flywheel spacer?

 

you sure its a 2001 6.0?

the 99-00 6.0 and early 4.8 manual trans engines have a longer crank

 

Yea I ordered a flywheel for a 2001 6.0 from advance auto. Now whether it's the right one or not, idk. It is an 1 1/2" from back of block to surface of flywheel. Is this right?

 

what crank do you have ? early long flange or short normal LS1 flange? they are almost flush w/seal

 

old school trannys need to have flywheel spaced

 

Depending on the crank

 

yes but that only applies to the early 6.0s and some 4.8s

 

It has the short flange. I got it figured out a while back. Had to go with an adjustable throw out bearing, ram 1550 flywheel, and a ram clutch
