What I was trying to say that bone stock these cars were hard pressed to run mid 16's in the 1/4. Even the limited production 6.6 Pontiac engine was only 180 h.p. The compression ratio on the 6.6 Olds motor was about 8.5 to 1 and was rated at 160 h.p. It's biggest problem was the cat converter which was the pancake design and really choked the exhaust. It wouldn't rev over 4,200 rpm but after it was removed it would pull to 4,800. Getting those T/A to run in the low 15's was a BIG DEAL in 1980 because the 4.9 turbo that replaced it was even more of a pig.
