I'm about to buy a 96 firebird 5.7 LT-1. I test drove it today, but it felt
kind of rough when in idle, but as soon as I steped on the gas, that thing
would spin tires. Is this a normal vibration with big motors? The oil
pressure would be at a quarter when idling, then half way or a little more
when cruising at normal speeds. Engine seemed normal, no smoke or noises.
Thanks for any comments since I have never ever driven big sport muscle cars
