Just my 2 cents here and I know you love your 2 sroke Clint, I picked up my 76 with the repowered the 8.3 cummins 4 stroke. My first 480 miles I filled it with 40 gal of fuel. Works out to about 12mpg, I have about 1500 miles to go so I will avg this to be more accurate but shouldnt be under 10.
. Avg speed 70-75 mph and lots of power. The best part is seeing the look on truckers faces when they see me passing them in this old classic doing 75-80!! The temp will come up some if I hold that speed but not much over 200. As for the value , I think it has substantially increased with this power train rather than if I were to have the old 555 rebuilt.
