Continuing with my Durango SRT theme, I am looking at adding the proper power to round out the project and am looking at options. I know our 5.7 Hemi is not the Ram-based 5.7, but which vehicle is the 2012 5.7 in the Durango most closely related to? Charger/Challenger, Jeep GC? Are all three of these the same? I know they are basically the same motor, but a variance in packaging can make the difference between a Maggie, etc. designed for one of these other vehicles fitting or not in the D. Biggest question/issue is the pulley alignment. Edelbrock confirmed for us that the heads line up on top, but if the pulley does not line up in the D, then a twin screw is out, unless someone develops a vehicle specific package. Step two is to look at the centrifugals.
My shop has no problem making minor adjustments the vacuum lines, hoses, air intake, fluid reservoirs, etc., and I am not worried about tuning any more as this will all be done with a custom tune on the dyno and street.
So, does anyone have the answer as to how close these engines are, and if one was to check a box to order a blower, which kit wold be the closest -- Charger, etc.?
