When you want to go STU-pid fast...

 

Did you know that Inertia Motorsports was the builder of the first 372, 383, 392 and 407 5.7L  and the 2nd 426 6.1L based HEMI engines in existence?  It's true!

 

Since we use custom CP brand pistons with all of our rotating assemblies and short blocks we can provide pistons for any desired compression ratio, ring package, wrist pin size and bore desired at no additional cost.  Additionally, we can adjust compression heights for stroke lengths not shown above such as stock stroke all forged setups or destroked engines.  Each of our stroker motors are assembled with the same attention to detail and close measurement of critical clearances.

 

Have questions about any of the packages listed below, or looking for something a little more custom, such as a motor built for nitrous or a supercharger?
