budget build 360

True. I do not have a stock engine around anymore to measure. Do you have a compression calculator on hand? Run the numbers with a 360 head @ 72 cc and a then again @ 65 for a typical Edel. head and again @ 55 for the W2. The head itself is available, just not assembled. (Another damn shame along with the W5 disappearing.)

Good idea. All these are with .170" deck clearance and zero piston head cc. So keep that in mind.

72cc= 7.4:1

65cc= 7.79:1

55cc= 8.48:1

Keep in mind this is also using .039 as a compressed thickness. I used .024 on the 55cc head for example and got 8.74:1. Plus, if your piston sits higher in the hole than .170", you'll have more there as well. That 55cc figure can be used for the W2 OR a slightly milled 302 or Magnum casting too.
