Bunch of Noob question from a Dutchman

9=month. 13=day. 72=year. If it is stock, it will be a lower compression 440, and should be a forged crank engine, which is good. If it is stock, it will have open chamber cylinder heads, probably 346's to take a guess. The heads will have a long part number cast under the valve covers. The last 3 digits indicate what head you have. All the open chamber heads are similar, so it doesn't really matter.

If you are going to retain the stock pistons, you won't have a lot of compression, so I would recommend keeping the cam small, and using a dual plane intake like an Edelbrock Performer, or Performer RPM. I like the RPM personally. A 750-850 cfm carb will do nicely.

Your rear axle will need upgrading for sure. Have fun.
