Larry, one of our research facilities in Europe measured bore distortion on a running engine that ran at 6,000 rpm. SAE Paper 2002-01-0485 has the results of the testing. It makes for an interesting read.

Thanks Greg, I will read it then I will get Chris to understand it for me.

We wanted to tweak our ring package just a little, so I called Total Seal for the rings. A pleasant surprise was everything was on the shelf and it will be shipped today.

I may try a Bob Gliden and build it without the aid of an engine stand.

Stan, I always want the car better than 50/50 and rear weight biased enough to have the car go straight in a wheel stand. The iron head engine makes more power than the aluminum heads , but the aluminum heads go A to B much more consistent.

In going through some old information I discovered a torque sequence for the main caps. After following directions I rechecked housing bore and it was good.

Bob Toy finished rewiring the pink car and it looks organized and easy to work on. Still have to scale car and test.

Re: Dumbo The Flying Elephant
 

Iron head engine has lower hp rating ie lighter weight ? Why not fix the car to go straight and consistent?

Re: Dumbo The Flying Elephant
 

Glenn the iron head engine makes more power and is rated higher.

NCAA basketball is over until Thursday. I will be able to see the relationship between the deck plates and the heads as to how round and straight the cylinders are.

Re: Dumbo The Flying Elephant
 

The plates and the heads are real close, only a few tenths difference.

Better equipment = better results only if the operator is skilled and experienced. Jeff Taylor Performance is such a place. I went there with the liners everywhere, over .002 variation in places, the end result was the cylinders were round and straight and only .001 bigger. I got one more build or of my pistons.

I miss a lot from my youth, I’m sure everyone can come up with a punch line, but I miss my eye sight the most. After cleaning and inspection I decided to reuse the main bearings. I caught the light just right and the saw a piece of trash on the bearing that would not wipe clean. The bearing was starting to flake off. That would have been pretty after a few dyno pulls.

Re: Dumbo The Flying Elephant
 

Is it a Polymer coating that was flaking? If so why did you re-use it?

Re: Dumbo The Flying Elephant
 

It was the Babbit flaking

I think I'm done!
