Default 99 4.8 mated to t56

I currently have a 6.0 liter with a t56 in a 99 truck. It originally had a 4.8. I want to put the 4.8 back in so I can drive it this summer and save on gas....while freshening the 6.o.

What mods am I looking at?

I cant remember...lol

I have a 02 clutch and flywheel out of a vette in the truck right now. I also am using a vette slave cylinder.

I know the crank sticks out father on the 4.8.

Is it a direct bolt in?

I thought the crank was longer on the early 6.0s, not the 4.8s?

The 99 4.8's had a thicker crank flange. There was a guy on here a looong time ago that got it done with a T56 but it required some kind of goofy spacer bewtixt the bell housing and the trans. It'd be easier just to grab a new 4.8 from a junk yard for $200 since they can't even give them away.

Either that or use a T-56 designed to be behind an LT-1.

I have an f-body LT1, but the clutch is a pull type not a push, does that matter at all?
