I'm seriously looking at doing a 6.0 with L92 heads on it instead of building a new big block as I had planned for my 78 K20 after driving a friends new Escalade. All I can say is wow. Those new cylinder heads make a huge difference over the cathedral port heads on the 5.3 & 6.0 engines I have owned.

I can get the whole 6.0 engine and the new L92 heads for right about what a better set of aluminum cylinder heads cost for the big block. It is definitely getting EFI so that will add quite a bit to the big block expense. Add in the massive weight savings of the LSx engines over the big block and it is a no contest decision.

I will probably do a stock 6.0 / 4L80E swap to get it on the road then upgrade the heads, cam & intake later on.

Maybe in a few years there will be a more L92 & LS3 engines around used so getting the all aluminum 6.2 with the better heads already on it will be easier and less expensive.
