Can you race a Mustang Saleen 625 hp in Nascar type races?

May be...

You cannot race a Mustang Saleen-a great car by the way-in any NASCAR sanctioned event.

However, if you are interested, you can road race the car in some SCCA classes as well as perhaps-once you become sanctioned-in the Grand American Rolex Sports Car Series Presented by Crown Royal Cask #16. Log onto SCCA.com and GrandAmerican.com to find out what you would need to do to make that happen.

In the past, Saleen's did race in the American LeMans Series, but those were Saleen Corvettes.

An oval track would be a total waste for that car.

Or are they made only for road courses?

NASCAR mandates the car that is driven in all races. A mustang, for now, is not raced in NASCAR. Any one of the sports car circuits are where they would be raced.

No it doesnt fit the Ford Fusion Templates and Specifications!!!!!

No it would not pass inspection , but you might be able to try running it against the pace car . lol
Good Luck.

no...

Nope. Even if you did, you would get smoked!!!

No...It has to be a nascar approved car....I call them spec cars...They are designed to nascars specifications....Remember their is nothing stock about them!!!!

No, good luck getting the body and frame through inspection. The COT is cookie cutter bodies for all manufacturers.
