No way. pin it. The key groove has to be precision machined in the snout. It has to be the proper depth, width and square down the axis. That's not going to happen in the car. Pinning is effective and easily done.

1000%I would just pin it in a few precise locations. Heck, if ya have to, just do it in 3 spots. It wont go anywhere then.
But I think 2 will be just fine..
Dont trust 1 location.
I can post pictures of what high HP does to a single pinning job. Not to mention the HUGE bill it cost to fix the tuners F'up. (that i paid for)

How do you drill balancer. The collar that ATI sells with their kit looks like it only does the crank ?
Any help would be appreciated.

Is it a radial or axial pinning kit? I prefer to pin them using the axial method from the front. My balancer came with a 3/16" keyway cut in it and I used a carbide bit to radius it for my stock crank so the pin would fit properly. I had the dampner hub replaced back to a 3/16" keyway slot since my Callies crank has a key cut in it from the factory.
