My '58 Apache w/ 235 started unexpectedly the other day. I was cranking to find TDC after it had been off for several years and it just kicked over even though the ignition was off. Fortunately my hands were clear of any moving parts...
I have replaced the engine and wiring harnesses up front while the truck was out of commission, so I'm guessing I got some wiring wrong. Original ignition switch. If anyone can tell me where to start with trouble shooting, I'd be mighty obliged.
