Jeff,
The only cam's I know of that can use the stock pushrod is the freedom cam its built off the base circle.
In each of the other cases you will require other than a harley cam to buy adjustable pushrods and pushrod tubes.
Can't just answer your question because there is not enough information about what your really trying to accomplish.
Where you like to ride, type of riding you do, rpm range, 1 up 2 up.
Bolt in Harley, Freedom, Zippers
Gear Drive
Andrews, Woods, Mackie, T-Man, Wes Brown, Freedom, S&S, Zippers
You can also convert your bike to the 07 cam plate and use the new roller chain.
Just ask Mrs. WeCVO why you might consider the 07 version or the Gear Drives.
Places to buy would be direct from some of these guys, Zinotti's, Drag Specialties, Chicago Harley, J&P Cycle
