I told Ken Shaffer last night. To mark a stick. As to the distance from the top of the intermediate oil pump shaft. To the top of the engine block. At the distributor hole. He then came to my house this morning. So, we could compare the distance between his 455. And a rebuilt 455 that I have laying around here. On an engine stand. Ken's shaft is .470-inch higher in the block than mine. Ken S intermediate shaft is 8.062 in. Ken H has measured two shafts. At 8.125, and 8.187 in. So, Ken S saft is the shortest already. Then there's another issue. By shimming the distributor up. The distributor drive gear is running .470 in higher than it should be. In relationship to the cam gear. Not good. I need to put some bluing on the driven gear. Just to see how bad it is. (The gear pattern will be on the very end of that driven gear.)
As another note. When the engine is running. The distributor drive gears. Are pulling the distributor main shaft down. So, what stop/stops? Are keeping that main shaft. Down ward forces. From damaging the pick-up coil? I need to take a good distributor apart. I use to have some around. But Ken Saffer has destroyed ALL of them. GRIN. I've said for about a year now. That something is up with that new oil pump. That Ken S installed back then.
Engines, drivetrains, and suspensions are my thing. With all the engines that I've built over a lot of years. This is truly a new one.
