They weigh a LOT more than your fox. For better comparison look at a 1995 or so GT. Even though the Fbody still weighs a bit more, better comparison as far as weight goes. Never underestimate am Fbody, they make great power, whether LT1 or LS1!

200lbs is only 2 tenths difference, the extra 80 rated HP should be close to 8 tenths for that E.T. range. (THE GENERAL RULE OF THUMB IS THAT FOR EVERY 100 LBS REMOVED, ACCELERATION WILL IMPROVE BY .10 SECONDS IN THE 1/4 MILE. THIS IS EQUIVALENT TO ADDING 10 HP. THIS IS WHY RACE CARS ARE STRIPPED DOWN AS MUCH AS POSSIBLE. THE BOTTOM LINE IS THAT LESS VEHICLE WEIGHT OR MASS EQUALS A MUCH IMPROVED POWER TO WEIGHT RATIO (PWR).) Sorry about the caps it was cut and paste from a web page. This is the point I'm trying to make, sure there are faster times on the F-body's for that year but there are faster times on the GT as well.
As far as the Fox I have....1987-93 MUSTANG 5.0 CURB WEIGHTS
(ALL CURB WEIGHTS ARE APPROXIMATES
1989 GT CONVERTIBLE 3,640*
1989 LX 5.0 CONVERTIBLE 3 ,550**
1987-93 GT HATCH BACK 3,300***
1987-93 LX 5.0 HATCH BACK 3,200***
1987-93 LX 5.0 NOTCH BACK 3,050***
I hope this is not offending anyone, I just think it's interesting to discuss our competition.
