Project 6-71 340 Demon

I finally have some more progress. After having delays on getting parts over Christmas and the wife having surgery, (she's doing real good), I finally got out to the garage again.

I started putting the bottom end together. I installed the main bearings, checked them with a micrometer and came up with .0026 to .0028 clearance. I then set the crank in and checked it with plasti-guage just to make sure. It appeared to be about the same. I think that those clearances will work fine so I started assembly. The ARP bolts went in real easy and after I went through the torque sequence the crank turned real nice and smooth. I then moved on to the Eagle H-beams. Damn they are nice to work with. I checked the bearing clearances and came up with .0020 and .0021 across the board. I assembled the pistons rings and rods and then installed them in their cylinders. The whole operation took me about 7 hours but I work slow and make sure everything is the way I want it. I check things, check them again and then check them again. All in all it was a good day.

Here are a few pics. You can probably see where they had to add metal when they balanced the rotating assembly.

Hopefully it won't be so long until the next update.
