Before the Drag Pack was released, I called Donato and he told me the Magnum version was going to be cheaper, about $30k and something around $39k for the Hemi engines. I wanted to go with the Magnum, but when final pricing was released, all the engines were the same price. Might as well go for the Hemi if the prices are the same. I ended up buying a street Challenger for less that had a working transmission and rear axle and suspension.
