Slant 6 HEI
We have Black Widows here, profusely, not so many Brown Recluse. This one came in via a distributor order from Louisiana, and, yes, confirmed Brown Recluse, two days from bite to 1st operation. I took the spider to the operating hospital, 90 miles from my home, all the way to Reno, confirmed Brown Recluse.
There were three choices for me, and the spider bite, lose hand, die, or fight to stay alive. I chose the latter, being a Vietnam vet, combat experience, 5th S/F Group.
The GM reluctor and pickup have problems, in that they are critical on gap between pickup and reluctor, not easily worked out. Simply, MOPAR pickup is also weak, and like the Ford, doesn't like traveling in an arc past the reluctor. So, I build a pivot in the center of the distributor, and make the pickup move concentric to the reluctor. I have done a bunch of them to Direct Connection, and stock MOPAR distributors, and all Fords built with original eccentric pickup setups.
