Finally pinned my crank - A pictorial

I pinned the crank when it was 6.0L. When I stopped in during the 408 build to see how it was going, he had it fully assembled already. I saw the old balancer installed, with pins, and no new holes. Being paranoid, I right away thought he put the stock crank back in until I saw it by all my other parts. We had talked about the pinning kit and I knew he didn't have one, so I had to ask how the hell he did it. In a milling machine, with a ball end mill. They do it all the time because they do blower motors.

I just pinned mine on Monday. I had a main thrust bearing go on my built 5.3 back when I started all this madness and when I put the 6.0 in the mechanic put my crank bolt in at 280 ft/lbs. Needless to say, it had all of us sweating bullets Monday, we were for sure that bolt was gonna break. We had a 6' monkey bar on it. KySilvy was kind enough to send me his tool, we actually opted to not use it and the mechanic doing my trans build used a Snap On setup he had. I didn't want to break Ky's tool. LOL 6' bar and it wasn't moving. It was crazy, moving the motor on the mounts cushion. Crazy!
I am pinned now though. Thanks anyway Ky, I'll get that back in the mail you next week!

I was a little worried about doing it to my truck. Couple weeks ago I helped a buddy do one in his GTO with a MP122. There isn't near as much room between the crank and radiator in a GTO. He had bought an angle drill but it wouldn't fit. Long story but due to time we tackled it drilling the holes with a die grinder. It took us 3-4 hours to drill them! No torque in a die grinder.
With the drill I used it literally took about 30 seconds per side to drill the holes. I was so happy!
