I was just having this discussion with a couple of guys the other day. One is a buddy of mine fresh outta UTI and 2 other guys in their 60's/70's with over 50 years experience. Those were the exact numbers I was given by them but we were talking about different motors. Some good ole american muscle, the 2JZ-GTE and the RB series motors.
