My Teardown @ St Louis.....

Well, my first teardown didnt go as expected. We were chosen to go to the barn Friday after class. After removing the head for Wayne (D5) and crew to inspect, the following numbers were found,

Intake runners, 137.x on a 140cc max
Exhaust runner, 57.x on a 60cc max
Combustion chamber, 55.x on a 54.9 min
Bore 3.935, stroke 3.005
.040 total deck, piston to head

Also, bore, stroke, ring height, carb, intake, wheelbase, etc all checked good. Valves were pulled and valve job and valves inspected, all also good.

Then came the camshaft. Intake checked .396 on a .399 max. The exhaust checked .405 on a .399 We rolled and checked it a couple of times, with a range of .402 to .406

I couldnt believe it. I do my own assembly and knew exactly what I had, or so I thought. Travis knew where I went wrong and told me what to check when I got home. He was right, my checking lifter is a Comp Cams solid and the plunger is well short of the height of the hydraulic Smith lifter that's in the engine, right around .100 shorter. A rookie engine assembling mistake on my part, and I take full responsiblity for my ignorance. This resulted in my DQ.

First off, I want to apologize to my son and wife for embarrasing them. I feel I let them down and I'm sorry. 2nd, I want to apologize to Tom Moock for our class runoff in Belle Rose, I am sorry for that as I hadnt changed anything since then, so it was undoubtedly wrong then also.

And, I want to thank the Tech guys for showing me respect. They were very professional and went far above showing extra patience with me, because of it being my first time. Hell, I filled out the whole teardown card not knowing most of the area was for Wayne to put his notes in. (I was just trying to help.......)

I'll see you guys at Indy with it apart for Tech to check and hopefully put this mess behind me.
