(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.
