max compression to run on 93
#4
What are your can specs, mainly the intake valve closing point? The thing you have to look at is dcr and cranking psi.
In my 408 I'm running 12.5:1 static compression, but my can drops dcr down to pump gas friendly 8.22:1
From all I've found in most cases 8.5:1 dcr and 200psi is about max for 92-93 octane

Thanks for the thread; I am in the process of making my LS1 a 383 as well. I will be doing a TSP 383 kit, -3cc pistons and either 64 cc or 63 cc LS6 heads from TSP.
I called Wiseco and I will be between 11.4 - 11.7 on compression, I just need to talk to Matt on what cam would be best.
