Chrysler engine

I'm trying to figure out if my motor is a 318 or a 360, can anyone tell me how to find this out..

Thanks in advance,..

#1:
Pull the heads, make a mold of the combustion chamber with your kids play doh. Drop the play doh impression in a graduated beaker, add a known amount of water, and record the volume.

#2:
Measure the diameter of a cylinder. Turn the engine over by hand and measure the stroke.

Pi*r(squared)* stroke will give you the swept volume of the cylinder.

Add #1 and #2 together and multiply by eight.

Seriously, I'll bet these guys can help:
