Speedmaster rockers

I have Smith Brothers 3/8 pushrods with a cup at the rocker end. I'm far from a math wiz so I’m a little confused by your calculations but I clearly understand your .050 - .060 longer intake pushrods. Sounds like I’ll be making a call to Smith Brothers. I appreciate the information!


Yeah, they will tell you that 3/8 pushrod is enough. It’s not. I’ll see if I have some double taper pushrods out there and take a picture. I know I have some single taper stuff.
