I've run up to a 200 shot on a factory crank and rods. Both MoparBilly and Monte gave me some pointers via PM(s) on this board and the old MoparChat, but I'm no expert. This new Hemi stands a chance of pushing my car to the limits of the chassis without nitrous. No-Prep 8th mile racing is getting popular out here in AZ. I'm keeping the old nitrous set up on the car until I see how it runs.
