I will have an orange block wither way. I'll paint it up the way I want it before I drop it in.

Either way both are iorn blocks with forged internals with a warranty. The B-15 can be had for 8k if I remember correctly, the lesser for 6k.

A stock LS3 can handle 8 psi safely. I'd think that the lesser crate LSX would be able to go to 15ish?
I'm certainly not arguing as you obviously know more about them than I do. I don't know a lot about the LSX crates. I'd just think that a forged piston and an iron block would be better than stock.

Both LSX376 engines have forged powdered metal rods, probably the same rod LS3s have. One engine has cast crank and the other has forged crank. The cast crank engine has the LS3 cam in it and the forged crank engine has the LS7 cam in it.

Makes sense because the shop I talked to said that it had the same rods as the LS3.

I'd have been pissed buying the lower one. BUT, at 9 to 1 compression that 8 pounds will go much further. haha
