yeah 385 is low with the vortech, depending on the gearing, and boots level, elevation, etc... for 6500 i would have it taken to a performance shop and checked out befor buying.. sounds like a nice car if its done right. and DO NOT wash the motor from the underside EVER optipark on LT1 is a major PITA but is 96 so it should be a nice one and easier to tune and keep and eye on because of the OBDII
