Idk, it's not like you can just cut it in half, it's harder to figure out.

NHRA correction factor for 1/4 to 1/8 mile times is 1.57. 13.90's 1/4 would be 8.80's 1/8 mile.

When you get your time slip and are ready to go faster, go for some 4.56's and a 10" 3500 stall.

Then ditch the 882 heads for any of the good aftermarket heads.

It will go like hell.

Lol! If he is stock you've probably got nothing to worry about. I've got a 1995 mustang gt 5.O 5speed as well. They run 14.9's bone stock... just pray he doesn't have full bolt-on's like mine, or he'll be running 13.5's. 302 mustangs respond very well to mild mods... that's good seeing as the 5.0 only has 215 to 225 horsepower.

Full bolt-ons being: 3.73 gears, CAI, Headers/full exhaust, Underdrive Pulleys... etc NOT including cam or heads.

What does your Z28 weigh? If you weigh 3400 pounds, and have 357 horsepower you should smoke him pretty darn good... heck with 357 horsepower I see absolutely no reason why you shouldn't be running high to mid 12's.

Of course I have no idea how much the 2nd gen F-bodies weigh???
