If your running 11:1 compression or better, sure!! But for a stock 5.0 it would be over kill!:shrug: You can safely advance your timing to 14-15 degree's with 93 octane.
When I had stock gears I added a 2800 stall converter first. Before I couldnt even power brake it!:shrug: After the stall I could lite em up just by punching it out! :nice:
your brother used your car :shrug: Is anything smashed up? anything ruined? see if theres any damage before you go off the deep end here! And for what its worth, when I was younger I "always" snuck my brothers car out!! Only got caught once,, by my dad!!:(
Im not!!:shrug:
I'll get a pic up of my stang as soon as I replace the brake lite lense..Our cars could be twins cept mines a hatch and the trim is painted white like the rest of the car!! Are those Bassani 3 inch tips?
