Pushrod length

Post by Billygeterdone »

I completed my first stroker build recently. I was hoping for some feedback from some more experienced/ knowledgeable people. I used racetec pistons, scat 9000 crank, scat 4.0 connecting rods, comp modified 235, johnson lifers. Stock rockers. 7120 head.
I'm hearing what I believe is lifter tick. I probably have 30k miles.
1) could my lifters need to be replaced already due to my spring pressure?
2) I used a 9.6 pushrod is that the correct length? My head and deck were only surfaced.

Thank you for any help much appreciated.

Check the lifter preload on all 12 lifters. You should only need to turn the rocker arm bolts another 1/2-3/4 turn (equivalent to 0.030"-0.045") beyond the zero lash point to reach the proper torque.
