I did get my Rimac tester to repeat to the .001'' when testing for coil bind. It was an easy fix. Remove POS pinion support and make new brass bearing and install. Modify stop to install 5" dial indicator. Make positive stop for table. Fab table extension for dial indicator. Use 123 blocks to calibrate. Rube Goldberg we be so proud.

In 16 springs the range of coil bind varied.022". That would not be so bad if hardened shims were available in increments of .001". If target is CB is .050" and I can't get closer than .010" I missed it by 20%.

Talk about all new never run parts. The installed height difference on all intake valves only varies less than .010" and same for the exhaust valves. To get stuff closer I'm going to try a different set of springs and or make something to get the needed force on the seat.

Test fit my T&D rockers today, what a great piece of work by Brad Rounds and crew. I had to do absolutely nothing, which was real nice for a change. I also found out that the rockers can be installed backwards. All this while I listen to Uncle Bob at the D3 race.

Looking forward to the shop being closed for three days. I should get a lot done. It was 25 years ago we missed racing on Memorial Day weekend. I was building the truck and that weekend was header weekend at Gary Jennings. Brought the truck over less dog house.

Wiring is slow but it should easy to find and fix if necessary. Installed height, coil bind, seat pressure, open pressure, shims, and spring assignment is coming together. Rocker arms are done.
