I just swapped in my new motor

Dyno at 425hp
484 tq
Will post pics Asap


My car is set up with 3:73 gear ratio. Hooker Exhaust, Ram Air, MSD Ignition.

What do you think I will run the the quarter mile and top speed.

i predict synchronizers in your lap and input shafts on the ground. that t5 will not hold up to that kinda hp. have fun!

I agree.

You should consider a TKO or a beefed T56, kelham. If you're gentle you might make it last, but your rear axle is also potential trouble if you got a 10 bolt and you stall it high on the launch. So if you do get a tranny, look at an axle too.

That being said, if your motor's already dynoed 425 hp, you should see somewheres in the 12s with a good run. Where exactly depends on your 60'.

Def a 12 second slip with a decent 60ft. I would look into a G force T56 before i would swap in a T56 thats for sure. This is coming from somone that did swap in a T56 in his thirdgen. Also like already stated careful with the rear, cuz that thing will break. With a 26" tire, 3.73's and a wild guess of a 6300RPM redline you should be able to hit 130 or so in 4th gear, and about 185 or so at redline(if you got the power to do that in 5th gear).

I think you will be in the low twelves if the drivetrain can hold up and you get good traction.

Easy low 12s if you have perfect traction and something doesnt let go first, and with that kind of torque it will. But hell thats the best way to show em whos boss. :-) I do all the time. (Freaking rear ends)
