Rich; I'd beg borrow or steal a 3 bolt timing set and throw the .528 solid in that thing. I fell in love with that cam. Idles almost like a stocker and has torque off the bottom like you wouldn't believe. The last 440 I had in my truck was alot like what you're working with. I installed the .528 in it. I took the heap to the strip and had trouble keeping my drivers door shut on launch. It was twisting the body so hard the drivers door would pop open. It also was picking the front tires 6-8" off the ground on launch. Dave
