When mine was 100 percent stock, I was running 15.90's @ 82 mph. That's a:

Peanut cammed 305 TPI
700R4
3.23

I'm "slightly" quicker nowadays.

Dennis91 those times are a bit conservative. I ran a 14.6 bone stock with in my L98 IROC. 3.27 rear. I've seen L69 Z28s run 14.9 before too, the 5-speed ones with the 3.73s.

Everything you just said is flawed. You cant give exact #'s like that for any car. Also, all L03's came with hydrolic roller cams. Your #'s seem a bit off for everything.
