Ben, Didn't see it and although on this list we may not all agree we seem to be much more tolerant of others ideas. Mind you the proof is always in the pudding. On PL don't sweat it, it's aggravation you don't need.   I have had exposure to some good ideas from the other list, but equally I've had a lot of help from this list.   Tell me Ben why, didn't you go for the Ford C6 planetary reduction box, you could machine any parts you need for yourself.  George (down under)   /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////   George, The main reason I didn't go with the planetary reduction is that design does not offset crank/ prop centerline. On a V8 that needs to be done to get the motor to fit into a cowling. That is why my next creation will probably be a rotary,, they are practically bulletproof, light,readily available and hanging around here the positive tips will help in a successful install.   Thanks again guys,   Ben.   Ben, Will look forward to seeing your efforts in this regard. George
