I have come across a cheap l5p bottom end with 20k miles from a crashed truck, will lly heads fit the l5p block or will l5p rotating assembly fit into the lly?

Heads fit but takes custom y-bridge, pushrods, few other things to even work. Then you're missing out on the largest gains of the L5P platform, the cylinder head flow improvements.

I believe the LBZ/LMM ECMs can be modified to use the OEM L5P reluctor wheel, I do not know if anyone has tried with an E60 controller.

Following in the event that someone has, I know we've not messed with any L5P swaps yet.
