Length of push rods
Hi I beleive the length that you need for a 390 with adjustable rockers is 9.157 long and you need the ball to cup push rodsand I think they are 11/32 in dia At least that is what it shows in my book because the non adjustables are different they are 5/16 in dia and longer at 9.564 to 9.584 long I hope this helps you can get this information out of the paw catalog have fun

Dennis (DSC) can hook you up with the correct pushrods. The crane pushrods used to be the wrong length. I don't know if they fixed that or not.

The adjustable rockers have a slightly higher ratio than the non adjustables. 1.76 vs 1.73. this is their only advantage over the non adjustables, other than they can makeup for shortfalls in the rocker geometry when swapping in a bigger cam.
