Gary,

Don't remember exactly; think I got it started at 30 degrees before TDC. Didn't have a timing light.

When I first started it, it was running terribly -- I had set the valves using the harmonic balancer TDC markings, which was off. I readjusted the valves using the TDC markings on the new balancer cover and it fired up and ran much better. Then, I tried moving the distributor and listening to the motor as it was warming up. After 10 minutes, it hit 200 degrees which scared me, and I shut it down. That's when the loud bang happened thru the exhaust and I haven't tried to restart it. Thought I'd try to start it tomorrow and see what happens.

It's 2:30 AM here and I have to get some sleep so I won't be able to answer you until tomorrow.

Thanks,

Jim
