Should I try to start the engine before I start tearing it down for restoration or don't even worry about it now? I have a 1942 chevy with the same motor that I know will run. I was planning on using the 42 engine for now with just cleaning it up. Then I could go thru the 46 after I got everything else done. What say you all?

Can they be checked on the bench? Also is the key for the ignition also the same for the door and the glove box? I found a key laying on the floor of the cab in the rest of the old spark plugs and dirt and seeds from the squirrels I guess. | | | | | Joined: Jan 2005 Posts: 1,682 Extreme Gabster | | Extreme Gabster Joined: Jan 2005 Posts: 1,682 | I'd say it all depends on how far you'll be tearing the engine down.
If your 'teardown' is going to be mostly cosmetic, like pulling it all apart, cleaning it up, painting, and re-assembly, then i'd definately try firing it up before hand to make sure there isn't any serious problems with the motor.
If you're doing a from the block up rebuild with all new parts and stuff.. well, i'd not even bother trying to start it.
If the motor turns free, it's very likely you could get it running with little effort, and decide to just hose it down with some engine brite and run it the way it is!
an idea is only stupid if you think about it rationally.

Charge meter can be checked with a large load resistor (or 6V headlight) and a 6V battery with the gauge tied in series with the load. Strap a digital meter in paralel with the original gauge to check its reading for accuracy.
Speedometer is easy.. just hook up the speedo cable to the speedometer, and chuck the other end of the cable into a cordless drill and spin it about 300-500 rpm.
Not sure how you'd test oil pressure.. short of connecting an air hose to the back of the gauge and putting a known amount of pressure into it.
