Well I measured my pushrods and came up with 8.7"Int. and 8.75" Ex.
This was with comp stainless rockers, frpp solid roller cam, there crane lifters, and dove heads with stainless 351c valves, no lash caps.
In a previous post I was concerned with the 5/16" ball ends but it turns out that is all my lifters will accept. In my measurements I also included the
.017" for the ball end radius.
How does this all sound?
With these lengths it moves or sweeps the least on the valve tips and start just off center of the valve. .050" more or less on either intake or exaust it increases the sweeping motion dramatically.
Right now at 1/2 cam lift the pushrod is square to the pushrod cup or seat in the rocker itself and fully outboard on the sweeping motion, and from there on it moves back towards the valve centerline.
Did I miss anything?
All comments welcome and thanks in advance!
