Slant 6 HEI
I had to see the spider bite photos:
DAVE's small-body HEI's. A year ago, the top of my foot looked like the 1st photo after a possible insect bite. Started as just a small white pimple, then so bad after 4 days I could barely walk and had to visit an Urgent Care in AL to drain it and get anti-biotics. Looked like photos of brown recluse bites and I had been in VA where they live the week before (toured The Wilderness Battlefield after work), then worked in flip-flops in my CA backyard that weekend, with many Black Widows, but no Recluses (I think). Regardless, I suspect the infection was bacterial since spider-venom is a nerve agent which attacks your whole body. There are nasty microbes sitting on your skin awaiting for a deep puncture. Even a rose thorn can allow entry and cause you to lose a thumb if not treated. Especially bad if it gets into your veins (red streaks).
Oh yeah, discussing HEI pickups, the multi-finger pickups like GM uses (last photo before spider-bite) seem better since it tolerates shifts in concentricity between the reluctor and pickup (averages all the fingers), unlike the single sensor in the in the Mopar distributor. Ningbo's Ready-To-Run HEI distributor ($45 on ebay) uses the same multi-finger pickup, but Ningbo doesn't make one for the slant (Mopar SB, BB, RB only).
