any one ever tryed making putting the cam shaft over head? how would you run a timing chain up? also has anyone ever gotten a steel fly wheel made?
 
Take and eliminate the camshaft all together, then put electronic selonoids to open/close the valves in the valve cover. Would cost alot of money and would be a very good set up providing the electric doesn't go out! Just an idea!
 
(quoted from post at 17:21:40 09/16/08) How big of a B are you trying to make. You have enough room to leave the cam in for a big crank.

Im not trying to build anything im just thinking of ideas to try to make more power out of a JD is all.
 
Or you could just install a flux capacitor! Then you could take your OHC John Deere back to 1855 so maybe it would be competitive!
 
The short answer is, yes, I believe a SOHC can be done on a Deere. I am not going to go into details on the board on how I have thought of engineering it.

I believe the benefits would be that it would eliminate pushrod flex and camshaft flex on a stroke clearenced cam. I know it only runs 1000 rpm with almost no spring pressure, but a 2ft long pushrod cant stay perfectly straight.

A severly stroke clearenced cam will flex just setting the valves, so at running speed, with the oil pump loading it; I dont really want to think about how much the cam is moving.

I have not prusued the project farther because the best reason I came up with for doing it was so that I could say that I built one....and that really inst that good a reason.

Yeah Doc Brown, thats what i could do! and I could also bring a life time supply of fuel thats a good enough grade so the motor dont ping either! Ill get right on making a flux capacitor!!
