Some more details your stand would help. In hopes of preventing possble injury, here's my experience. I have a cheap engine stand. It is a 3 point stand, two casters on the cross under the mount and one on the extension that goes under the engine. When I first mountd the six on it, I couldn't get the approx. center of the engine down to the pivot point of the engine mount. I didn't want to take time to drill another set hole to get the center down, I'd watch it, bad idea. I was working on the engine a few days later and turned around and as I did nudged the motor, it went over so quick, I was surprised. I promply drilled the holes to get the center down. Getting the center down was much better, still not quite as good as the stand I had previously borrowed. I'l watch it. The more I worked with it the more I didn't like it. I finally put a cross piece on replacing the single front caster. To sum it up, It may carry the wieght, but it better have four points, and be able to mount the engines center about even with mount pivot. I'm not sure how you find the engines weight balance point. Be sure if feels rock solid. When that engine starts to fall there's no stopping it.
