Silly question. Does anyone know if there is an adapter plate and pump drive gear/shaft setup in existence to put a Roosamaster injector pump on a 8.1L Deere?

get yourself a Roosa that has an A or P pump mounting flange. (whichever your block is)Only DM's had those flanges, so it'd be difficult to do a .450 DB. Some road graders with a 531 had a roosa with a P pump mount flange.

If you machine the driveshaft drive tang down for the DB head you can put a .45 right in a DM housing. Done it several times.

Thanks for the info. Which driveshaft and gear will work with the 8.1 block and timing gears?

No idea on that one. Wrong shade of green for me.

The reason for this thought is right now I am pulling a JD 4320 in farm stock speed limit classes with a stock appearing pump rule. The tractor is very competitive and I have no plans on changing classes at this time but would like to have an engine that is a little more capable than the stock 404 and also way more versatile for possible future class upgrades such as open farm, hot farm, A and P pump rules.I was just wondering if this had been done before or even possible.
