If a stock 5.0 runs low 14's, so does my SC. My buddy has a CLEAN (65,000 mile)90 convertible 5.0 5 speed with only exhaust and CAI. He cant do any better than mid 15's on the gtec (i know, i know...it's a convertible and, gasp, a gtec), while my sc in the exact same location was pulling down 14.9's to low 15's. His best as of yet, before the exhaust was a low 10 in the eighth, without wheelspin. From a 55 punch, he slowly pulled me until right before he hit the next gear, and from about 80 up it was funny. a stock 90's 5.0 only puts down around 180 hp. and 86 I believe was still the speed density type fuel injection (like my 88 Turbo Coupe) so it would probablly be less. A stock LT1 F-body will run low 14's stock, and they decimate 5.0 in a stock to stock race. I would put a whole paycheck on a stock LT1 camero automatic vs. a stock 5 speed 5.0 hardtop. Bone stock with BFG radials on it, and one might get near a 14.5. Another friends 5.0 had ported heads, cai, exhaust, subframe connectors and sticky tires and he netted a low 9 in the eighth mile next to my 9.67 pass in my 88 Turbo. As reference, a 96 GT 5-speed with 99 heads, cams, and intake with 3.73:1 gears and exhaust and a bit of wheelspin went 9.12 (next to my dismal low 10 in the SC)
