I do have some information about these 8-port SH engines. The PT28XM1AC-P8 is the pull start verson of this powerful engine. I have just completed the break in one in my XTM mmt which as most of you know is a really big truck. To make a long story short it was keeping up with my buddy’s savage with a three speed. It was a little hard to start do to the pinch but paid off quickly once broken in. I still have much tuning to do and can run up to 40% per SH so I expect this to be a real head turner. My supplier claim that this engine is only available in limited supply in the US so I maybe one of a handful of sources. Once the engine is tuned and ready to go will link video to show this monster move. If you would like to get your hands on one feel free to contact me at
