already got some interest in splitting these up...i'll only do it if i have a buyer for the cam and a buyer for the pushrods. pushrods are spoken for IF that's the case, need a buyer for the cam or a buyer for both.

the dyno #'s in my sig are the link...but there it is. the 2nd graph shows power relative to RPM, whereas the first is MPH. the car pulled HARD all the way to 7K, i loved it, but i'm greedy and need more power!
