Help! knock sensor clearance issues
The connector on my knock sensor on my Ramjet 350 is touching my headers 
Does anyone know if there is a different knock sensor with a 90 degree angled connection that i could use? This one comes straight out.
Is there another location i could put it? This one is screwed into the water drain in the middle of the block.
If it helps, the knock sensor part number that comes with the RJ 350 is 10456126

Every Delco knock sensor I've seen has used the same design, so I believe you're out of luck for a 90 degree connector. As far as positioning it elsewhere, again that's probably not going to easily cure things. IIRC, all of the "off the shelf" ESC calibrations for first gen sbc's are tuned for the noise signature at the drain plug. Unless there's something incredibly horsepower-creating about those headers, I'd consider modifying them a touch to give a little clearance for the sensor wiring.

You are correct. Unfortunately the 4.3 is famous for lousy ESC calibrations due to nasty noise signatures (trust me on this one). Chevy always went back to the drain hole location for the eight cylinder engines.
