I am eyeing a stroker kit (this MMX one or this Arrington one) to convert my stock 6.4L (I've got a 2017 SRT 392) into a 426 and have a few questions. It looks like the kit comes with the crankshaft, rods, and pistons. Would I need to replace my stock camshaft at all for this to work? I'd like the car to idle smoothly as it's a daily driver, so I am currently assuming that in addition to the kit, I would only need a tune after. Is that correct?
