The 1990 Mustang LX breaks at 13.22 with a stick and a 220 HP factor. Its derated 5 HP. OEM is 225 HP. Factory shipping wt is 2908. Thats a natural F/PS with a 13.75 index. 13.0 X 220 HP=2860 plus the 170 for the driver is 3030 total on the scales. OEM exhaust manifols open or headers with a real muffler. slicks allowed. Blue printing the engine allowed and cam can be a regrind as long as the lift, duration, and overlap checks. OEM valve spring pressures required. spools are not supposed to be allowed but who ever checks....LOL. Pretty much like pre 1985 stock except for mufflers when using headers. .Pure stock is at 1 full pound breaks starting at 8 thru and including 16.
I see Mike Carr beat me to it.....LOL he had a better light.
