beefing up my 318???

If you can, pull the air cleaner (the wing nut on the very top of the engine... It holds the big round air filter) and take a couple pictures of the engine from the driver's side and the passenger's side. Good, clear, and try to get clear close ups. A lot can be told just from those. The pics you show look ok but a lot is hidden. I dont think getting an intake and carb are waranted just yet.
