So im wondering what I can epect with my car and mods the first time to the track. Car is a 93 coupe with a 308 with stock crank and rods, trw pistons, stock cam, avenger aluminum heads, victor jr intake, holley street avenger 670 carb, msd distributor, msd 6a, holley blue pump, bbk shorty headers, h-pipe, 2 chamber flows, stock gearing probably 3.08 and stock suspension. All this is gonna be done with the 17x9.5 cobra rims with 275x45's on the rears. I know the combo is mismatched from the gear, cam and intke but I just bought the car and thats what it came with. Any guesstimates?? Also what can I epect to gain with changing to the n-41 cam, air gap intake and 3.73's?? Thanks

You should be 13's at a minimum.

You might get 13s, 14s would be expected with hard compound radials, high gears and stock suspension. You will probably have trouble getting the car off the line. If it does have 3.08s they may make it easier to get the car off the line with out excessive wheel spin. If is does have 3.08s you won't need 4th gear, just run it through the traps in 3rd. Depending on what cam is in the enginef and how it is degreed. You could get trap speeds in the 110 mph range, possibly higher, but with the multiple mismatches probably lower. I would not worry about the times the car runs at this point, because you know there are multiple mismatches at this point. At this point the mph will be more important than ET. There is a scale on the return road at the track, weigh the car while you are in it. With the mph and weight you can then figure the rear wheel hp, and then get a better idea of what the car is capeable of, with traction and the correct gears.
