Four cylinder, four cycle, Spark ignition. 1.032" bore,1.094" stroke. Designed  by Ron Colonna.  Ron sells plans for this engine at .

The engine is based on Ron's book, but I changed the way the crank bolts in my , the crank pins where ground ,and the rod journals. the lifters were wire EDM cut , wire EDM only works when the shape can be cut through the workpiece, the cams were hardened and ground......the crank was bolted in so the bolts hold the bearing webs against the oil inlet.......I had to make a special set of wrenches to bolt in the crank here's a pics
