What abou the other combos? What is a fair and honest rating in the eyes of the peers? What would you have rated them at if you were putting them in the guide? Again not talking class just HP?

As far as the supercharged cars go, I'd say 500 is about right for the smaller blower cars. The ones like yours and the COPO with the 2.9L blower maybe 20-30 more, I'm not sure how much better it is.

The 427 COPO would be closer around 460 I'd say, and the 428/427 CJ around 440-450. The 2010 352 CJ should be around 400, as should the 2012 363 (comparing it to the 5.7L hemi which still qualifies at the top). The 2010 281 CJ should probably be 310-315 or so, and the 2012 302 maybe 360-370. I'd put the 2013 302 CJ around 410-415.

The 5.7L and 6.1L DPs seem to be rated pretty fair now (421 and 440), the 6.4 probably needs another 20 or so to be rated similar to the 6.1, and the 5.9 should be around 375.

These are just my estimations as to what I think would be a lot closer, some still might be a little too soft, some maybe a little too hard. It's also difficult to compare when you get to the higher classes because the indexes as you move from A->CC->BB etc get so much tougher.
