I don't have that peice of lit listing the Rock Island power units, but I do have lit. and prices for the 409D, 419G, 519LP, and 509D. There were several flywheel options w/wo rad., various out put assys., and mounting frames and rails.

We bought 2 336BDT power units from Sandhill Equipment in Bassett, Nebraska to repower 770 gas tractors. If you got that engine from Freddy it could well be one we took out of a 770, and put back in the power unit skid pack. WHAT A DIFFERENCE, after the transplant. Those small jurnal 336Ts were real kick asz engines. We doubled the 251G's HP, but the 4 plate pto could be smoked easily, and we did not over weight and over tire them. They had to slip a little to survive. We did play with trany pressure and tension on the bellview spring of the TL plate in the power shift. The 8spd just went in the usual tillage gears, up hills and down without having to shift. We also installed factory manifolding, oil coolers, and turbos from the 336Ts on 267S That lit them up also. I can't remember how many 70 series tractors that we installed turbos on, 7-10s, but it was a dozen plus. We also installed a couple of M&Ws on 1030s but combustion temp. and limited diff. in performance was disapointing. The indirect combustion design did not respond significantly to turbocharging, due to slow combustion and limited free air flow.

Today's Featured Article - Product Review: Lead Substitutes - by Mike Schordine. Lead was oriinally added to gasoline as an upper cylinder lubricant. It lubes the valves and seats. If you rebuild the motor, you could use hardened seats and valves, and unleaded fuel. But if your old tractor runs good, a simple lead substitute added to the gas is a perfectly reasonable solution. And, if you are like me, your tractor is under cover, but it sits outside. So with every temperature change, the humidity in the air collects in the fuel tank, in the form of water. ...
