Chad's 68 Camaro V3.0 build. LS3 & TCI goodies

I'd look at the engine vitals first in regards to the vibration. All 8 firing, fuel pressure, engine tune, etc...

My stock LS2 makes 28-30 psi at idle hot. What weight oil are you running? Mast may loosen up their clearances and that could require heavier oil to get a pressure that makes you feel fuzzy. 50-60 psi at redline should suffice, hot.
