Slant 6 Overheating

FrozenCaveman,

Next time, start a new post so less confusing to readers, and always tell us your year, model, and engine, as relevant. Nice to have another slant owner nearby. Better to post this in the slant six forum. The more advance you can get without pinging makes more power, better economy, and less pollution. Pinging depends on gas quality and temperature, which is why all modern engines have knock sensors.

You can take the setup off an 85-95 GM V-8 like I did for all my 60's cars. The knock module has a single output "5 V knock, 0 V no knock" which you could rig to an LED in the cabin. The knock sensor (1-wire) screws into your block drain, directly for a SB or BB or with a 3/8 to 1/4" NPT bushing for a slant (Ace Hardware). Don't worry too much about V-8 vs straight six. I read that GM used the same sensor in multiple engines. That they are all push-rod engines w/ cast iron blocks is probably more important.
