Ai got back to me today and their response was that there are more important factors than just DCR. Cylinder pressure for one is more important. Also, ensuring I have a clean air mixture, ie no oil ingestion, is a part of the equation. So I'm no too concerned with it any more. I'll trust these guys and what they're telling me. They've done this many times before. I'm going to shoot for an 11 to 11.5:1 compression ration. That's .5 to 1 higher than stock. I'm sure I'll be fine since I'm fully forged and we seem to have pretty good gas in this area.
I do wonder if I should go ahead and plan for a catch can on the PVC line. Historically, LT motors don't have the oil ingestion issue LS motors do. I guess I can always add it later if I end up needing one.
Also, anyone know of a quality forged piston I can run that has a 10 to 13cc dish? I'd like to keep my quench tight. Those DSS pistons I found on Summit I don't know anything about. Mahle, SRP, and Wiseco all only have a 5cc piston or a boosted application piston from what I can find.
Thanks everyone
