Want to know if a 6.4 hemi will fit into a 2006 Dodge Charger R/T and also will a supercharger from a 6.2 Hellcat will fit into the 6.4 or a 6.1 Hemi?

 

Sure it will fit ,what alterations do I need to do thou

 

Lots of differences in the motors..... it might physically bolt in, but, getting it to run might be challenging...... I think the 6.4 is going to have MDS, and variable cam timing as well...... So, mixing and matching will be interesting.... especially getting the trans to work as well. The 6.x engines may also be wider..... and not physically fit in the engine compartment, but, not 100% sure on that.

 

It will physically bolt in, however both are VVT engines, your PCM will not run them. It will require wiring and PCM changes. Muscle Motors quoted me $13,000 to install a new engine and complete wiring and computer changes. Stock NAG1 and most of the rest of the driveline will most likely not hold up to a hellcat.

LOL....06 R/T has MDS as well...all 3rd generation hemis, be it either 5.7, 6.1, 6.2 or 6.4 are identical externally packing and sizewise with the exception of the blower on the 6.2.
