Here's what I was up to tonight:









I've also been cleaning the front cover, rear seal cover, and the S-52 intake manifold :P I plan to have the motor togeather except for the cams by next week. In a couple of weeks I should have it back in the chassis and ready to fire up.

Last weekend I had a friend come over with a special tool to install the camshaft without breaking it. Here's a picture of the tool while we were installing the exhaust cam:





Also, he helped me set the timing on the cams and took a video of the cam adjustment in action:

I placed the motor last Friday, and have been working to hook it up since.

I know that the 30lb injectors aren't going to fly, but since they're the ones I have a current tune for, they're going to be used to start the motor for the first time in over three years. I still need to fix the power steering hose, but at $220 for a new one and no sources for a second hand one, I'm waiting untill next month.

I had to pull the motor one more time as I couldn't get the clutch slave cylinder back into the transmission. While it was out, I also welded up a slight tear in one of the transmission nuts and pounded it back into shape. I also welded washers to the radiator core where the A/C condenser mounts. I was using this for the hood pins which pulled through, now it's nice, solid, and painted silver. I've only got to install the radiator and oil cooler and I'll be ready to light this puppy off. I should be ready to run this weekends double/double at AAA Speedway.

It's alive!!!

Looks like this weekend I'll finally be

Well maybe not. I guess it was too much to hope that the radiator had survived intact. It's got a little weaper in one of the tubes. I'll probably just go with an OE replacement ~$200.

I was going to go to a test and tune day last week, but then the weather intervened. I didn't feel like getting stuck on the wrong side of the mountain for a couple of days for the pass to clear, also driving in the rain has a lack of appeal. So, I've gone over the car once more, stringed the toe, and made a gauge to measure and adjust camber. I also gave the trailer a once over. This Saturday there's another test and tune day forcast high is 67* and 0% chance of rain, low in the pass is 34* so I'll have to keep an eye out for black ice on the drive. Can't wait to get back out there and put some break-in miles on the motor.

Has a successfu, but long, day yesterday. I left the house at 4 dark 30, and made it to Buttonwillow 3 hours later. The run groups were alternated between open wheel and closed wheel, and closed wheel was up for the first run, but before the track was opened we were allowed to take "Sedan Laps" because of fog. I took the last sedan lap.

With everything seeming to be going well, I got in line for the first run group. My main objective for the day was to just run some break in laps and get the oil warm. So during the first couple of sessions I kept the motor below 5000 rpm. After the first session, as I was driving in I was hearing a cricket like sound, which I found to be comming from the body. Once I opneed the hood I found a little oil leak, with a little drip hanging off a banjo bolt, I found the source, tightened it up, and cleaned the leaked oil up with a little simple green.
