I'm new to the world of truck ownership having recently purchased a 66 C10 fleetside from a Missouri farmer for next to nothing. I drove it back to Maryland smoking all the way, using more oil than gas. I decided to step out on faith and rebuild the engine. I took it all apart, and rebuilt it just fine...I think. Anyway, my problem is that I didn't take any pictures and the process has been taking a long time, since August, and now I'm stuck. Please help me with three questions. Where does the oil pressure sending line enter the block? Does the intake/exhaust side of the head have two studs upon which the gasket fits or are there six bolts which hold the in/ex on (I only have five bolts and the guys who did the valve work sent back one burnt valve in a bag with two studs) and lastly because I have a 1971 250 engine in the truck, and it has a breakerless ignition I can't follow the wiring diagram for a 66 and I don't know which wires go to the plug on the fire wall and which go to the bendix on the starter. I am new (obviously)to the world of clasic trucks, and I know I sound somewhat stupid but if anyone out there could help me I would be most appreciative.
