Fastest Duster on stockish suspension?

Shooting for 125-126 mph.
29” tire and 4.10’s at that speed is 6000rpm at the drive shaft.
Add in 8-10% converter slip...... you’re at 65-6600 engine rpm.
Good place to be for lots of trouble free runs with a decent 408/416.

A 28” tire would add about 200rpm.

Looking at it a step deeper......
Any half way decently set up car(not being run at high altitude tracks) should be able to run at a performance level within about 10% of the corrected dyno hp and what’s predicted based on the power/weight ratio.
I usually plan pessimisticaly.
So, I’m figuring on weighing 3500lbs and needing 600hp(STP corrected).

Take 10% off the 600 power number, you’re at 540hp.

6.5lbs/hp puts you at 10.52@126, which if you weigh 3500lbs, is 538hp.

If the car is lighter, or is better than a 90% combo...... it’ll just go quicker.
