I'm building a 512 stroker out of my 440. Swapped it over to roller cam and this whole process is new to me and a learning experience. We figured out how to measure the pushrod length, Cam was on base circle and tdc. We did the whole process and measured from ball end to bottom of the cup.. Its a howards 565 hydraulic roller with Harland Sharp 1.5 rockers. we cam up with 8.059 on exhaust and 8.072 on intake. i know there are a lot of things to consider when it comes to the length. does it sound like I'm in the ball park? just looking for some input. i don't need any smart ass comments . just tryin to make sure this is right. Thanks for any help!
