4l80e and LS2 Crate Motor Help
 

I am about ready to order my drivetrain for my 70 Chevelle Project but need some help with a few things. I used an iron block 6.0 out of a HD 2500 Truck that was backed with a 4l80e. I plan to keep the 80e and bolt it to a crate ls2. The LS2 description says it comes with a flywheel for an automatic transmission but what else will I need? I plan to buy a new converter but am not sure what else ill need to make it work.

you may need a crank spacer or a custom converter with the extra space added onto it. Apparently some trucks came with a longer crankshaft and don't need the spacer, no idea how to tell though.Otherwise the crank won't reach a normal 4L80E converter snout to locate it. I used the spacer as I was converting my 4L80E and converter from a standard small block to an LS2.

You'll also need 5 trans to block bolts, metric for the LS2. The sixth bolt doesn't exist on the LS2, but five are fine. Sorry, don't remember the thread size.

You also need a trans controller to run the transmission.
