Has anyone on here had any experience with an angle valve O-320 built using GO-480 jugs/pistons on a narrow deck O-320 bottom end? I have access to the parts to create such a Frankenstein but am curious as to the end results and feasibility. Compression ratio of the 480 is 8.7:1. Apparently there are some airboat guys down south that have done this and are guessing about 170hp is the result. Just thought I'd throw it out there and see what you guys might now.
