Tough class to build into. I know because I'm still trying. Iron heads with inline valves only and max of 366 factory cid. 10.5 lbs per cid. One 750 cfm 4 bbl. Approved heads are available from Dart for Chevy and Marcarty or DCI Motorsports for Pontiac. Us Ford racers are limited to factory N351 heads made for circle track racing. A 351 N head Ford can make 500 to 600 hp in circle track trim. If you ran a Mopar in CS it would have to be an inline wedge with factory heads. No hemis allowed in CS.

The CS record is 9.39 at 140.91 with a '98 Pontiac. If that's a 3200 lb car, the Wallace Racing calculator says it takes 600 to 700 hp to make that speed and ET.
