If a sbc has 12 pounds at idle hot (700rpms 180 deg) and 30-35 cruising (14-1600 rpm) and 50 anything over 4k does this make it bad. The motor is new and yes at a idle I would agree it is low(but its a chevy)when its hot but in no way do I think the motor is hurt. as I was always told 7 psi per 1000 rpm is min and fine. The thing runs drives sounds great. Also I could turn it up to 900 and it sits at 20 at idle.
