We own a 1980 FC35 that had a 210 NA 3208. It was certainly leisurely driving in any kind of hills. 20MPH second gear with every truck passing us was not unusual. Recently had the engine replaced with a rebuild 250 3208 Turbo. The results are amazing, we now pass trucks going up hills and only shifted into third when I had to slow down for a truck and then passed him. Next we are considering changing the gear ratio in the rear end to a lower ratio to lower the rpm's while cruising.

Just for reference, my 1980 FC31 w/the original 210 NA will rarely fall below 38 mph even on steep grades; typically someone has slowed me down and I can't regain momentum to accelerate while pulling the upgrade. 1000' to 1500'.

It seems that there was one mountain pass between Kansas and oregon when I was first bringing the coach home that my speed dropped to about 25 mph. But that may be a mental myth because I was dead tired, could easily have been 35 mph insteed. Who knows how high I was (in feet).

High altitude however is different from steep grades. 20 mph speeds on grades make since w/a NA if we're talking a few thousand feet or more.

Set your altimeter to 29.92 inches of mercury to see what altitude your engine thinks it's at. I believe we loose something like 3% engine power per 1000' of climb. This is where turbos shine.
