I did a short test but it didn't turnout as good as I would have hoped. It started to rain so I wasn't able to get a better video done. The frame rate of the camera makes reading the A/F gauge almost impossible.
The original main body is a 650 4777-7 with a 2 corner idle. The secondary metering block has no option for a power valve. I've got the idle mixture screws set at 1 1/2 turn out.
Initial timing is 22 deg and full advance is 34. I made my own bushing to give me 12 deg of advance. I have a MSD 6AL with their 8545 distributor with a heavy silver and light silver springs.
The cam is a Comp XE275HL with 231/237 @ .050 installed at 106.
I think I answered all of the questions that wouldn't be answered in the video.
