They can certainly quit making the Mustang and still do NASCAR.
I wouldn't be surprised if NASCAR switched to SUV/CUV's
Chevrolet still runs the Camaro every Sunday
plus they can just stick some other name on the car. They used to run a Taurus....
And other races....Ford SuperVan anyone?
It's mentioned in this thread but I'm not sure if anyone linked the video

if you're going to compare numbers, at least be accurate.
Where is this 150 to 300 jump at 3,000rpm you're speaking of?
It's only adding about 50ft-lb at 3k
takes it from 305 to 350-ish
Edit: added a cleaner image from them
Basically the same as S550 numbers as you would expect. Not quite as big of a gain because the factory 93 tunes were a little hotter but about the same end result
Souped up versions of the Aurora engine (based on the Northstar). But it looked like a Viper interior with GM partsbin stuff instead of Dodge
seemed like a really cool car at the time
