What would it take to bolt up a 70 gas block to a Diesel tractor?

I wanted to utilize the 3rd main to make a high rpm puller. If there was a slight possibilty I would try it.I have done some wacky stuff with a G that was definately too much trouble.

Sounds like a big project, but I think it can be done.. but I think I would try using the diesel block and head. You would have to do some serious fabercation on the intake and not sure what it would take on the governor housing if that is where you wanted to run your distributor.. Actually I have an idea for that too.. Could put the distriutor where the hydraulic pump is.. And on the engine.. take all the injectors and pumps out. Do what U want with the block.. bore it to whatever.. get the piston to the compression ratio you want.. or just mill off the diesel pistons to get your ratio.. For spark plugs, either have hole put in the side of the block, or even better have them put in the head.. I don't think you could used the injector holes.. not sure if there is enough material there to bore out that big.. (Could even leave the injectors in there, but would be better to have them welded shut..) You would probably have to change the cam.. but who knows.. Never even looked that close at the cam on my diesel.. but sure the lobes are different... If you really wanted to get tricky.. could use the extra lobe on the cam with a cam sensor and a coil pack to fire each cylinders.. not sure how the advance would work.. Well I'm just throwing out some ideas here.. Like you said, if you have gone wild with a G, you know what U are in for.. I guess you don't have an RPM limit, or going to try pulling in an open class.. Good luck.. JDGnut

Talked to a reliable person who caught a G converted to two stroke beating everything else while pulling. Would like to know how they did the conversion.Anything with $$$$$$$ An G or 70 with a custom light weight crank, titanium rods & light weight pistons could rev up with less weight. Breathing is limited therefore torque with the small ports and valves relative to cylinder size. At some modest more rpm is less power. Two cylinder were made to efficiently burn low cost fuel.Ports,valves & cam reflects this. A Deere is made to clean up in truely stock and mild division II classes. A 350 corrvette engine is different from a 350 pickup engine. Two different jobs, two different engines. Same goes with compairing other makes of engines. The central plug in the injector hole will improve combustion efficiency compaired to a plug at the side of the cylinder. The lack of piston to head quench and the lack of a central plug near exhaust valve limits octain tolerance on all two cylinders. Spark is the easiest. An inductive pickup off the flywheel with electronic advance works well. A carb from Denny's and a generic mechanical govenor will handle the intake side.

Just trade the diesel for gas burner is thats what you want. It won't work and even if it did that's too much trouble.
