whats the spec on the motor ?

 

Congratulations Curry Dufrene on your Pro Sand Drags class win. I know you put a lot of work in and learned a hell of a lot more on the journey. Curry ran a 421 cub ported with custom cut domes and alky carbs setup by HJR.

Curry's first crack at building the 421 cub ended up sticking the rings. After figuring out what went wrong the second time out got him a class win.
