What is the difference in the 2010 and 2012 CJ Mustang

Rick,
Here's the deal with the 4V motors:
All the engines with the 4.0L blower are Superstock only.
The engines with the 2.3L Eaton blower have different cam lift and pulley sizes. The 2010 small blower engines were iron blocks also.

Hope this helps,
Wayne Kerr

I knew they had some new stock classes and I thought maybe those new classes would accomodate these.

Iron block with small blower.

It was a 2010, and it's the 4.6L N/A motor like Charlie Downing runs, similar to the engine that came in the pre-2011 Mustang GTs
