Oooohh!! Ok,,, This looks like a shelve the parts and get a book time. Its really a good idea to read up on projects before leaping in, and why do I know LOL Yeah, Ive lept before reading.
One of the best books I can recommend is called "chevrolet power". It will give you everything you need to know about engines. Mine is very old, but Im sure they are available. JR
Oh, and I have the third edition. So it may have changed. But it not a "power" type book meant for the gearhead. Its a GM technical manual that has great descriptions of all the working parts for stock engines. Shows some good pictures and diagrams of what all the parts are, including the cam or camshaft..
