Put me in line for those too. I had on of the cheapie ones, it sat too low. I did fire an engine on it but the headers burned the paint off. Oops. I don't think it would take much to get yours into a test stand. Old tach and a cheap set of sunpro gauges.
Heres the basic dimensions, sorry for the crappy cell phone pic. I left the back pretty open for the flywheel. i will also be making a guage/ign panel for it as well as a bolt-on radiator apparatus of some sort.
And here is my roommate taking it for a test drive.
