Crank Sensor
It's an '89 TBI setup. Computer is supposedly from a Dodge van, the rest is a mish mash of '88 318 and '90 360 parts. It's run flawlessly for 6 years or so on an '82 360. I've looked at adding the shutter wheel to a std. distributor, would require several custom machined parts. A spacer/mount for the advance plate and canister, and a removable upper shaft assembly with the mech. advance attached.
I recently built the '90 360 with a mild Hughes EFI roller, mildly ported 308's and .005" below deck flat tops which yield a 9.3 static compression ratio. The dynamic is just a touch under 8.5:1. The open chamber heads and compression ratio is the reason I want timing control, the PCM's curve is programmed for EGR and weak suck compression.
Can't get pics to load, I'll try again later.
The TBI is basically a bank fire in the respect that it triggers both injectors, once per Hall effect input. Really not much more than a computer controlled fuel leak.
