Don't worry about posting the planes and stuff guys, that's what has made doing this thread so much fun. Very appropriate on Veterans Day too.
Johnboy, thanks, and I had noticed you hadn't been around lately. You must have been building something, huh?
We've had a few issues to deal with in Don's T. His roller rockers and high lift cam are causing one rocker to contact the Moon valve covers he is insisting on running. Supposedly they have enough clearance for roller rockers, but I think the X cam just lifts a little too high for them. We had that problem early on and took a die grinder to the offending area under the valve cover. It is thick aluminum so there is plenty of meat there. However, when he started the car tonight it was running rough, so we pulled that valve cover and the same rocker was off of it's stud. At first we thought the polylock had come loose, but closer examination showed that the screw in stud had broken off right at the polylock.
He also had a bent pushrod. One of two things happened. Either that valve hit the piston, or the rocker arm hit the valve cover and twisted it. There are some gouges in the underside of the valve cover in that area, and I pulled that plug and looked at the top of the piston. It seems to have no marks on it. Tomorrow I am going to try to pickup a new screw in stud and pushrod. I think we are going to double gasket the valve cover to see if that extra clearance helps. Need to get some miles on the car before Daytona to see if the problem reoccurs.
Cars are SO MUCH fun.

I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
