How intense of a dragster do you guys think I can build with a 85 ATC250r stretched out chassis powered by a built alky driven CR 500 motor?

Built for 300' dirt and sand drags.


Any opinions or advice?


Thanks
Jay

The name of the company is Mac Racing Inc www.macracinginc.com and there is a article on it on the competing atv site that ends with source under product reviews

well, looks like I've got the ball rollin. I'm picking up my motor this weekend and it looks like a fellow forum member will be hooking me up with a chassis. I'll keep everyone posted on my progress.
