I’ve forgotten who told me this years ago, It’s just a math problem and try to get the numbers to like each other.

Sounds like Kenny Duttweiler- the entire world is just a math problem to be solved....

Frank I am not gifted! I try real hard to follow directions that smart people were kind enough to share with me.

Again thanks to all that have help me over the years.

At the PRI show I purchased every height micrometer that PAC sells. I thought I had all the bases covered, not so. The new Hemi is a little different from anything out there. To make a long story short I had to find an adapter in a piece of bar stock. It works well. Supper time got to go.

Setting up to make custom shims for Dumbo, sometimes times I feel like the Dumbo.

Today I should be able to assign springs to valves get them assembled and verify coil bind. It should be a busy day.

The reason for all the lathe work is the valve guide bosses have a healthy radius at the bottom where the spring cup or shim seat. Some of the shims I had to turn the OD down to fit the pockets or bore the ID to go over the guide boss.

Amazing all the work involved to build a fast race engine. Every detail needs to be checked and double checked. Awesome work Larry.

Re: Dumbo The Flying Elephant
 

The worst thing about building you own race engine is I have no one to blame but myself. I wake up in the middle of the night and think of things I need to do or forgot to do the day before. It makes for a less than restful night.

Ibuprofen-PM especially after crawling in and out or under the car.

Re: Dumbo The Flying Elephant
 

After redoing my coil bind set up three times I'm confident that my numbers are correct and repeatable. I have one head ready to bolt on for final check for clearance from coil bind. The other head is clean with seals, valves, and ready for spring assignment with assembly. It took two sets of springs to get eight springs on the intakes to all be at the same open and seat pressure. The exhaust side springs are 10 pounds lighter on open and seat.

Does anyone have the old style Larson Systems Solid Height Gage, if so I think I would be willing to purchase it.

More later
