Your 85 would be the only deviation from that formula in that all 85's received the L69 Cam which was much better than the LG4's but proved to be too good of a performer when matched against the General's flagship car, the Corvette.

Although not considered performers when compared to most of our 60's & 70's cars, they were good for the day with my original 1987 LB9/MM5/G92 IROC in bone stock condition pulling a 14.57 @ 91.71 time slip with close to 100k (real) miles on the clock and after driving to the track. That kind of time was stock Grand National territory back in the early 90's.

Obviously that cam change made a BIG difference. I had a 86 TA with the 305, auto, WS6 that was dead stock. I was the second owner with only 27k miles. I bracket raced it for one entire season and the best I ever got out of it was a 15.9. It generally ran in the 16.1 range.
