The few high end Gen 3 Hemi engine building shops have long block packages comparable to this. You can pick and choose the internals and in fact go beyond the level in this package if you want to pay the price. The two big differences between this DSR package and the Hellephant is it has the standard iron BGE block vs the Hellephant’s aluminum block and of coarse it is sporting the new 3.0 Whipple vs the 3.0 IHI on the Hellephant. I suspect that the Whipple is superior performance wise but nobody knows much about the IHI due to the fact that they’ve only seen the light of day on the Hellephants and they aren’t really out there doing anything for comparison. I’ll keep what I think about running that 1150 hp motor on pump gas to myself 🤓
