This is the twin cylinder horizontal engine that I designed and built over the past two months. I will be posting all of the engineering drawings in the download section of this website in the next couple of weeks. This engine runs very very nice, and is quite powerfull. The engine is not quite finished yet---I have to fabricate a classier air intake manifold, and replace some of the cobbled up port plugs and wrist pins, but--Hey---Its a Runner!!!! Enough said---Enjoy the video.---Brian
