Keep in mind that if you swap the engine, you're going to have to swap damn near everything under the car too. I'm not spun up on the intricacies of the rear end, TC, drive axles, and so on. However, to get any of the SRT features to work, you're going to have to gut the suspension and replace them with the adaptable ones. I'm willing to bet that the R/T's driveline isn't capable of handling the power, so you're likely going to have to replace all of that, too.

The car will also be uninsurable as the swap is illegal according to the EPA (per the law, an engine swap can only take place if the unit has full EGR/smog controls, catalytic converters AND the incoming engine is appropriate for that year AND produces the same or LESS pollutants than the original engine). If you lie and tell your insurance that it's just an R/T and you ever cause a loss or file a claim and the adjuster notices the Hellcat engine, you're going to not only lose your coverage, but will likely be sued into oblivion. Just things to think on.

Sounds like a procharger would be the better idea?

Are you implying something? The combo I bought came from a reputable place like CPP, receipt and all.
They're being grammar Nazis ;)

That said....would you want a Durango Hellcat steering wheel for your swap too?
Just sayin'

I didn't know basically any of that. That is camel fingers crazy. The fact that there is so much litigation about EVERYTHING makes me literally sick to my stomach. On the other hand that goes to show how fuel efficiency was never on the thought process during the first glory days. Lol, when any modern setup is cleaner than the originals.

Yep, most of the people you see dropping Hellephant engines into modern Jeeps and what-not on YouTube are making illegal cars. I don't trust this current administration with their overpowered EPA. I'm not trying to tell folks not to do things, just trying to remind them that this current administration (cough) is almost violently stepping up code enforcement for things as simple as cat removals. Just do your research and understand what you're doing so you understand your risks.

Thanks for your input, I guess i'd have to do a parts comparison to see if the diffs, axles, etc are the same or not? I figured a r/t would have come from the factory with similar components but you could very well be right.

As for the other evil in Canada the government or insurance companies aren't trying to lock up our cars..... yet

An R/T is just a 5.7L with 385hp. I can almost assure you that they aren't putting 700hp driveshafts and drive axles in that thing :) The suspension in the Hellcat is a 3-stage electronically adjustable suspension. The R/T doesn't have this either.
