I was wondering if anyone could give me a realistic guess on this. I am wondering how much horsepower it will take to get a 3400 lbs car to run 12s.

www.smokemup.com has a calculator.

I copied a 400 horse sbc build up 3-4years ago out of a hotrod mag. put motor in a 3200lb. camaro and ran 12.6-12.8.
Now if you know how to tune a car you could prob. go a little faster. depending on other components.. just my 2 cent's good luck....

You'll need a little over 300 horsepower at the rear wheels to break into the 12's under ideal conditions. Realisticly 325 RWHP should do it.
Course it matters how much of a brick you're trying to move through the air.
I used to run a 69 Vette with a 406 and then put the same engine in a 72 Nova and the Nova went slower. I think the difference was about 1.5 MPH.
The 60 foot time is the most crucial part of a good ET. No matter how much HP you've got, you have to get it to the pavement.

It's not just your power that gets you in the 12's its how you get that power to the ground. If you engines got 400 and doesn't have a posi or the right tranny and flywheel weight it will not do you no good. Also in an old car your bushings can rob you of rwhp.
