The engine in question is the 258 in my CJ, but I used the timing light for my 57 Chevy 1/2 ton with a 235 as well, so I hope I'm sort of on topic. The reason the subject came up is that the Jeep wasn't running very well at all...no wonder, given how far the timing was out. So the Snap On light was accurate and my old light was not. It had been dropped and otherwise abused over the years by someone who will remain anonymous.
Bill,
I like the quotes in your sig...#2 is too true...
