For those not familiar with supercharged CJ's, as noted earlier the 2008 body style is different than the 2010 and newer.

All 2008 cars had an Iron Block with the 2.3L Eaton Blower.

In 2010 there were 2 supercharged engine options, both with aluminum blocks, a 2.3L Eaton blower and a 4.0L Whipple blower. The big blower engine has flat tops while the small blower engine has dished pistons.

2012 also had 2 supercharged options.
The 2012 big blower engine has dished pistons.
The 2012 small blower engine has a different supercharger pulley and cam lift than the 2010.

I hope this helps clarify the differences between the cars and the changes required to simply claim a different year car.

See you at the races,
Wayne Kerr
