    Im looking to go for it and put the 426 Hemi Hellephant in my 70 Challenger. What other frame stiffening or body mods do you all suggest to accept all this new power, already have the frame stiffeners installed. Thanks

    First if all, welcome to the forum. Please be sure to show us pictures of your car! Since you have sub frame connectors, the other options are torque boxes, radiator core support and inner front fender braces. All the parts can be bought at US Car Tools, or XV Racing Products LLC. I prefer the XV front fender braces, and dealing with them if you have a problem, but XV does not make toque boxes. You also might want to talk to XV since they make a complete front and rear suspension to help handling all that power.

    Depends on what you're gonna do with the car. Just that simple.

    That is some fine craftsmanship there Brian, that car will be as ridged as a tank.

    Fantastic car/work!
    The "V" behind the rear seat needs to be tied to the package tray and then to the floor in the corners. There is a lot of flex in that part of the car that gets overlooked by most.
