If you are limited to a box stock 3LM 466 then I would guess all you would need to do is double spring the torque limiter and the existing P.D. clutch should be fine. If you want added insurance install a P.D. clutch from a 7580 as it has an extra disk in both high and low sides.

I doubled the springs on my 8050 and with 425 hp got about 25 pulls out of it and on last pull it slipped in third high when I dumped clutch. Ive heard of tapping two 1/2 inch bolts into flywheel so the limiter has to stop against them. Have a shop with a balancer do this. My route will be is I remove springs, cut a round 1/4 inch plate and dowel it to flywheel so it can all be balanced and bolt limiter tight.
I recommend you add at least 20% Lucas hydraulic booster to your oil. I feel 20 wt oil is to light for extremes of pulling, myself I dumped in two gallons. The booster also increases pumps pressure, had mine checked with over 8000 hrs it registered 210 pounds, 5 pounds over. I also dumped four gallons into rear end. If you plan on using tractor for chores don't get to carried away the oils too thick. DO NOT put gear oil in it will destroy pumps.

Adding Lucas oil honey (or STP) wouldn't be on my "to-do" list for pulling applications with a wet clutch. The oil is constantly being thrown outwards into those wet clutch discs/plates (for lube) and has to be squeezed all out from in between the discs/plates before the clutch components can lock up. Adding to the viscosity of that oil will probably cause more slippage and smoother shifts....neither of which you want. Also your oil temps never get anywhere near normal operating temperature, so there is no need for thicker oil. If you need to reseal the clutch pistons because of old age, resealing would be the better choice.

Here is my theory for the added lubricity in the Lucas. I know off a puller with 700 hp who was shearing off the splines on his clutch plates and this was with the extra plates installed. When shifting from lo to hi the clutch splines that are made of soft copper are sliding on the steel hub, I suspect galling is occurring due to thin oil. Too much time out in the fields pondering, like our quarterback.
