How fast are big block Duster's.

If we say your car at the line will be 3000lbs and you have a genuine 525fly hp, and it can hook and run a good 60ft in the high 1.4's.(doubtful with 3.7's and a 3500 conv).....in theory that p/w can push you to 10.50's@128. If your chassis is not up to it however it should still go mid to low 11's I would've thought. If it was a race car only with a good rearend set up I would put 4.56's in it, a 4500 verter and 28>30" tall slicks on it, then you would be in the 10.50's.

To give you an idea, my 1969 440 pictured left, went 10.7@126 with only 484 fly hp....n/a
