This one took a while. It was a 3-circuit and he converted it to a 2-circuit, and then I had an engine let go shortly after getting it running. The new engine seems to like a lot more fuel due to the better cylinder sealing. We also have a weird cam that was originally for efi, so tuning this has been a challenge. Its big, its got way bigger chambers than a wedge, and a cam I would not normally even consider running....And man does it run.
