Here is a good read for a 318 hop up with simple bolt on parts. Many here have done something similar. http://www.moparmusclemagazine.com/techarticles/engine/mopp_0312_318_long_block_bolt_ons/index.html It's an easy motor to hop up since the factory parts left so much power on the table. I did a somewhat similar build with mine and MPG actually increased along with the power if you can resist using it.
