Anyone heard of SC's in the works for the 392? I'd be pretty interesting to see the kind of numbers one could put out. The Vortecs are putting out... what? 600+ when tuned right?

Then theirs the guys at SMS and Mr. Norms that are going all out with the Aluminum 426 Hemi's and getting 900 horse. Crazy stuff.

 

There are tons of classes in the oval track racing world that require flat-top pistons.
