Oh yeah, 90% of them were very slow. But I believe the H.O. cars were 83-84 (would have destroyed a mustang of that period) and with a 5 spd they ran with the 87-93 Stangs.
One of the Camaros i drove was the "Crossfire Injection" 305 which was the same injection setup used on the earlier '80s Corvettes...it had these cool vacuum operated scoops on the hood that would pop open when you matted the gas
