Peripheral port 13B idle
Homebrew 13B at idle; fabricated ports, header, intake manifold, etc, breathing through a Weber 48 IDA. Trying some tricks with porting and header design and it only fired up for the first time about an hour ago, so I have no idea of power output, and very little desire to make unrealistic guesses.
