Small roots blower for smallblock

I don't think you have enough timing in it yet. You might want to work your way up to 28 degrees and lock it out there. I have 31 degrees with a 340 that has a 6-71 on top and my static compression is 8.4 to 1.

Hey there Jack, how much boost are you running?
Scampin is running 8PSI

Perhaps we should start a thread here on how much boost psi and total timing people are running.
