Here are my final lengths for the pushrods...

Delta Intake Pushrod 5.840
Delta Exhaust Pushrod 6.150


I uploaded the excel sheet as well...

You need to actually measure. My base lobe is smaller than yours (barely) and I measured it to only need .030 longer. I will measure again when I have the heads on and torqued down to spec in the motor they are going in.

As far as rolling your eyes cause I have to machine a gear...wow. I had to anyway. It was supposed to be 1.5 degrees anyway so it doesn't matter if I gotta cut it different. 300+ gear work or 480 for a custom cam. It doesn't bother me one bit.

yah srry wrong smiley, couldnt find the doh one

[rickykline]

so to find the length of the new rods you take the difference of the base circles and divide by 2??

Correct..

maybe i'm wrong though.. what i see is the lifters sitting .073 and .096 further down in the lifter bores, in order to make up that difference and regain the propper preload i'm adding that difference to the pushrods. Seems all too basic to me.. am i missing something?

Here is a discussion from 3.5 yrs ago when I was looking into adjustable pushrods...
