440 Hemi 620hp

7.2L 440 Hemi?

The 440 isn't known to be a Hemi. In this case though it is! In this video we will be looking at a challenger RT with a 5.7L v8 hemi that is dropping a 440 in it. The n/a 440 crate engine typically rates around 620hp at the crank. This would likely be around 500+whp. Next we will see this beast on the dyno. Jannetty Racing is currently tuning and doing all the work on this 440 build. We will see 100% what these monster Hemi's are able to do.
