Got a 5.3/4l60e going into the Luv. The block, crank, rods, and pistons are at the machine shop. The bottom end will handle 500 hp with no problem, so I'm going to stick with the cracked rods. The block had been sitting out and has rust, so a visual inspection indicated it would have to go out to twenty thousandths over. I told him I might as well go 30 and get those 5 approximate extra cubic inches. 332 maybe?
I took the heads in last week only to find they both had casting cracks and could not be used. The engine is an 04, with dished pistons. The 09 on up has flat top pistons which will up the compression ratio a little. Don't know how much, but the guy at the machine shop knows how to figure that.
Also found out that with a cam and a good tune I can expect around 370 hp. That should make it a fun ride. More later, and pics as I get them.
