Ok, this might seem stupid or a waste of money... I own a 99L and im looking to build a nice 5.4. I was talking about starting with a salv. 5.4 but then this came to mind. How many wreaked L's are there in Oklahoma... So what would be the diffrence from a 99 f150 and a 99L, other than the rods, pistons, cams what not... is there any major diffrence in the block design? Thanks...
