You're right there...

A friend has a FFR with a Ford Motorsport 460 crate motor. We got into a run, (closed circuit course) him in the Cobra and me with my intake/headers/tune 508 rwhp Z06. We left from a stand still and by 100 I was ahead by 6 or 7 lengths and pulling on him harder and harder.. On a open track HPDE it would have been even uglier.

Interesting question:
How does a 3100 pound, 508rwhp Vette do with a 2650 pound, 465rwhp Cobra?
(I'm assuming the crate 460 made less power than 465 at the rear.)
At least over a quarter mile.
Does the weight difference equalize the power difference?
Last Vette I ran had no chance but I don't know if stock or modified as yours.

The ability to put it to the ground is typically lacking with the Cobra, more so than the vette with it's 325 or 345 wide sticky steam rollers (345/19 Michelin PS2s in my case) and typical better gearing. The aerodynamics of the vette is temendously better too. Also, a lot of "600 hp" cobras struggle to put 400 hp to the rear tires. I think that was around what his 460 Cobra was putting down.

Given equal traction, gearing and aerodynamics a 465 rwhp Cobra would in fact beat a 508 rwhp vette. The Cobra would have 5.7 lbs per HP whereas the vette would have 6.1. I'm not a quarter mile racer but the guys that are and have good abilities running like Z06s are getting 10.8x/10.9x @ around 130 with drag radials.

I agree. Hooking has always been the problem. A rolling launch is not much help either, you will go right through the tires unless you have great feel and experience with the car.
The aero is an interesting point. I've found it helps Vettes to 'maintain' a distance once past 100 MPH but the initial ground lost to the Cobra is not made up.
I did get burned by a Vortec-blown Vette with drag radials, couldn't leave on him with me on Hoosiers and he pulled very hard mid range on up.
