On my Hellcat swap, I did it all for under 20k. Thats everything, motor , trans, electrical, exhaust cooling system, etc, etc. I admit I got some good deals. Couldnt do it today with prices the way they are. Did ALL the work myself, so didnt have to pay anybody for anything. Yes its expensive, but my previous motor was a 451 that probably made around 600 hp, ran 10.80's and the drivability was crap. With this swap, Ive put more miles on the car the past 3 years that I have the previous 10 plus years, because it is so nice to drive! The drivability along with the power is a dream. Working on my next G3 swap currently in a 99 Dakota RT.
