I fully expect my head and cam 6.1 to run better than a 440 of similar compression, with a bigger cam and aluminum heads to be fair.

I went with the new Hemi for three reasons:

1. Reliability (roller cam, efi modern accessories and o rings everywhere)
2. Parts availability (no need for many aftermarket items when I can get dealer parts that are far better.)
3. Power (without saying..these heads made it worth it. )
