They were retooled circa mid 2007 along with many other items. Compared to the prev. generation that had super rough, very small ports....these new ones are much smoother, larger and much closer to oe max wedge stuff.

The chambers appear to be coming through on the small side
(77-78cc), so if they need to be nhra legal, plan on a little work in that area. Kind of nice to leave them alone for a 440-452 street/strip deal with a flat top, though.

300 seems like kind of a stretch, but is probably do-able? I'm sure the prototypes were flow tested but somehow that data was never dropped into my lap.





It's a good thing they got retooled as the original intent was to provide a viable alterative for stocker racers and the castings were so rough that they weren't really useable in stock. Not as much of a problem in SS as they can port them hard and fix a lot of casting stuff. I'd love to see the revised castings or get some info on them as well.
