How To??

rebuilding my first engine at this time as well, 360 too.
I have the Factory service manual for 1973 Plymouths. Service manuals a MUST for rebuilding the engine, all torque specs and valuable info in that, and in my opinion should be bought first thing once you buy the car, no book more valuable.
Also have "How to Rebuild the Small-Block Mopar" from SA-Design
http://www.amazon.com/dp/1932494545/?tag=joeychgo-20

And Mopar Performance's "Small Block 'A' Engines" book is a great parts selection guide and performance help.

I read each of these cover to cover before buying parts while the engine was at the machine shop, and have them all open as I build the engine.

Best of luck on your build!
