So my setup is a 383 ls in a 00 fbody. Compression is 10.30 to 1. Heads are trickflow 225 cnc ported but also hand ported after and opended up to a 245 runner. Cam is a brute speed blower cam. 1 7/8 lts and full bolt ons. My question is with that compression with a d1sc or f1a what is the max boost i can run? I have a front mount and goig to be running a good meth either alky or snow with multiple nozzles

A 9.5/1 compression ratio has always worked really well for me with boost, and we've run 16 psi on pump gas with methanol injection with this combination without any detonation problems. You should be able to run at least 12 psi with your current 10.3/1 compression ratio on pump gas and methanol.
I'm not sure if this answers your questions or not, I'm on my first cup of coffee... Bob
