Expiremental OM617 build
lol its actually a centrifugal supercharger impeller for a R-3350-23 i believe or it could be a -34 not entirely sure. it ate some fod so its scrap same for the valves the intake is 79mm across and the exhaust is 65. i also have a piston and jug assy(6.125" bore) all from working on a few old planes before.
as for the heads if i were gonna do that i would need to build some kind of basic flow bench and get some better tooling for porting. i do have the head that came off to test on so maybe i could be talked into it. there would also be the issue of shipping a cast iron head.
most of all the tinkering i am doing is just for my own entertainment. i don't seriously believe that i can get that much out of the 617. it just doesn't have the air flow capability to match the 60X 4 valve engines even with the porting and cam. that being said i actually enjoy doing things that pose more of a challenge. the lack of any bolt on solutions is fun it forces you to adapt other things and learn much more in the process. in the long run i am planning to turn the 300d into some kind of franken build. who knows where it will end up but i will never be entirely done tinkering thats for certain.
