Marc,
In the meantime, get some practical experience. Have you ever rebuilt an engine? If not, see if you can find a 302 in a breaker's yard, clean it up, take it apart bit by bit in a very methodical way. Box things up as you go; starting with the exterior accessories, then the induction (carb, throttle body, manifold(s)), Then the heads with the valve covers, rocker arms, pushrods (keep these very organized numbering them according to the cylinder they came from.) What, you don't know how the cylinders should be numbered? Well look it up on the web or get one of the many "how to build a ford v8" type books that are mentioned here on the forum. One of the first things you need to be able to do is get the No. 1 piston at TDC on compression (not exhaust.) Be saving your pennies while you are doing the outside stuff and by this time you should be able to buy an inexpensive engine stand (I just bought one for my R302 block for $40USD) and mount the block on it so you can flip it upside down and start tearing into the bottom end. Again, be very organized: keep the oil pump stuff together and keep the other stuff together by cylinder. Once you get the rod caps off cleaned and ordered, flip the block side ways and push each piston/rod assembly out. You can take the lifters out now too, if you didn't take them out once you had the heads off. You should know what the timing cover is by now so take all of that stuff off now. (If you don't know what something is, figure it out before you take it off!) Pull the timing set off and remove the cam. Bye the time you get to this point you will be amazed at how much you have learned about an internal combustion engine and the various methods engineers use to fasten things. Almost everyone of them is based on one simple concept when looked at in its finest elemental form - a ramp (or inclined plane as the books will call it, but which has been around as a ramp or its other form, a lever, since not long after man discovered how to put something in his mouth a see if he could eat it). Most of the rest are based on the most modern of technologies: the spring (its only been around since man learned to bend a stick and make a bow.)
Now take the block to an automotive machinist to measure, repair and hone as necessary. When he gives you the numbers (and that is all I am going to say at this point), gather together the replacements for the wear parts and any upgrade parts you need, get out your "how to build a..." book with all of the torque specs, hints and tips and put it back together again using the surprisingly few tools you will need to pick up with your saved pennies after buying the engine stand, which you will thank God that you bought one, especially now. Once you get the engine back together with the distributor in the right way round you will be well on the way.
Now go out and buy a book entitled "How to wire a Hot Rod."
I think you get the idea. Once you have finished this one, you'll be ready to start building a car. If you have enough self confidence, maybe you bought a beater to drive around in and fixed it up, maybe you can go straight to a GT40, but that is a pretty big jump. If you aren't sure, try something a little simpler the first time out, like a Locost roadster or a Cobra. While not child's play, they are a little more straight forward.
Good Luck and hang around 'cause there are a LOT of talented people on this forum.
Regards,
Lynn
