My buddy that I have beat about 4-5 times pretty easily that has (88 coupe - 306, edelbrock performer RPM, 600 carb, B303 cam, longtubes, underdrive pulleys, and pertronix, T5 with 2.79 gears, no that's not a misprint, 2.79's), thinks that a 86, with a stock 302 with 24# injectors, B303 cam, T5, and stock everything else can beat me even with my mods in the sig plus my future roller cam Comp Cams roller .512/.153 lift and .484/.496 duration setup. What a joke!!! What do you guys think? BTW, I've beat plenty of modded 5.0's, so I really don't think it's an issue. I put myself at somewhere in the 13's, what do you think? All I had to say to him was "Just wait, you'll see!".
well, if he had 4.11 gears i think he could handle you, at least it'd be a good race, but you should take both easy as is. The near stock one has little shot. edit: That is assuming you have a posi rear with gears, which, upon looking, i do not see in your sig. The 5.0 might handle you really easy if you don't have a posi rear...
