Sorry I forgot to say. It is a 1941 Ford coupe and it has a 350 engine with A/C everything else seem to be original. Thanks Jerry
The following is my opinion only. Everybody has one. You may not be interested in the drive train part but I included it anyway.
If you really need a manual for the early v8s I wonder whether having an antique car is the right thing for you(don't take that as an insult just my own experience with the lack of good manuals and how I had to overcome that)? It is very difficult to find a mechanic who knows anything about a flat head. Out of luck with the 350 engine.
IMHO Model A has much better repair manuals than v8. There just isn't a single good manual like the Les Andrews Model A books.
What do you really need mechanically? With a flat head v8 the valve lash is fixed and you need a special lathe grinder to adjust. Timing is set up on a machine off the car. The transmission is so easy a book is not absolutely necessary if you keep track of the parts before you take them out. The rear ends don't go bad much. The wiring is primitive.
A wiring diagram is useful although the ones I've seen weren't exactly user friendly and the best one I have was drawn up by a forum member. Yours being a hot rod you probably have the EZ wiring harness which is a easy as it get since all the wires are labeled.
The green bible is good to a point. It doesn't have many pictures. It is good to see if one year fits another one.
You can get an old Motor Manual for minimum info on the drive train. I have one and have never really used it as I am not overhauling the engine.
The Service Bulletins are very sparse and not nearly as detailed as Model A.
The V8 club books specific to your year are good for some things about authenticity but nothing mechanical.
There is a Body Parts Catalog but again pictures are not near enough.
Carburetors anyone? I bought a rebuilt one cheap that works great. I have no interest in rebuilding any.
My main reference is asking questions on this forum. 99 times out of 100 I get the right answer. The only question I didn't get a straight answer on was a woody part I took off and painted that no one had seen before. I got lots of humorous responses that made me laugh. After a long time I figured out where it went by myself.
Has this covered everything?
