Hi I am building a 2012 6.0 lz1 engine from a 2012 escalade to put in my 1970 C10 suburban mated to a T56 transmission. I am running a Lsa blower and Lsa heads, Brian Tooley stage 3 blower cam, rocker trunion update, .650 brian tooly dual springs, ls2 timing chain, ls7 lifters and trays, and pinned crankshaft dampener.
The thought just crossed my mind that I may have to gap the piston rings. Id rather not and just run it unless if its going to do damage to my pistons. The Lsa stock boost is around 8psi, I think because I have a smaller 6.0 instead of a 6.2 I may have more boost with the slightly smaller motor. I will be running the factory size pulley on the supercharger.

Seems like a call to the guy that sold you the cam may be in order, or some other expert.

What will the compression ratio be with LSA heads on it?

I think you're right, a smaller motor with same pulley drive ratio will have more boost, but its also about how well the motor flows, your cam may help flow so it won't be that big of a difference. It's ~12 cubic inches difference, I should think boost pressure won't be that different

Seems like many on here run tons of boost with turbos without saying they did anything to the rings..

But I'm no expert.

edit: according to wikipedia, the LZ1 has 10.8 to 1 compression and the LSA and LS9 have 9.1 to 1...

Never heard of that motor until today...lol. I went with an LY6 for my LSA setup and tossed the variable cam equipment.

If it came from a 12 lade.. its a 6.2
