Well, the car was bought for me, so it woulndnt be cheaper to buy an srt6 and also I have become emotionally attached to mine. my goal is 450 HP. I do not have the engine, it is at a junkyard for a good price. im not sure whats damaged which is why Im asking what parts are different. after i get an AMG engine, i plan on getting a dual cold air intake, a high flow exhaust, remove my catalytic converters, and get a smaller puller wheel for the supercharger, then a chip tuning. does that sound like i can get 450. it has 350 stock.
