Thanks everyone. There it was tucked right where Wally indicated. It's 3701946, so it's the '53 truck engine.
Now I just have to wait for the water pump, thermostat and housing and gaskets to show up. I didn't know they were not things I could just run to my local part place and pick up. I'm not sure why the starter wouldn't spin when it was in the engine. Maybe a dead spot on the armature? There's a local shop that will rebuild it for about $100 so I'm thinking about taking it in on Monday.
Next item to locate is a T-5. I'm beginning to remember how to judge the shift points on the non syncro tranny, but it's getting tiresome, and noisy, lol. It looks like the ones from S-10s are a better fit with the position of the shift lever closer to where it is now. I've been looking at some of the conversion posts and it looks like there's an issue with the input shaft length that has to be dealt with but other than that it seems to be a relatively simple fit.
Thanks again everyone,
Joe
