I had my 84(before the 6m transplant and before she died) pegged past 130....once i got my 85 i got her to pull even harder...so i went out with a friend in his mustang...and we were up about 140 in my 150000 stock 5m with no upgrades...on an ohio interstate...we slowed down due to traffic, but i dont' think i could have got much more out of her.
