Doug - I'm not Ralph, but I'll give you my opinion. The 4-speed transmission is a small negative. The 475 hp Detroit makes up for that and more. I'd like to have a 5- or 6-speed *and* the 475hp Detroit, but oh well. On Priscilla, the wide-open upshift point from third to fourth is about 55 mph. In practice, this means that I can climb a 5% or 6% grade pulling a small toad at about 55 mph in third. This translates into being passed only by vehicles weighing a lot less. Shifting to fourth drops too far on the power curve and acceleration is not possible on a grade that steep. With closer spaced gears I might be able to sustain 60mph or more. But I don't think even the mighty 8V92 Detroit would be able to climb such a grade at 75mph, which is the speed in fourth gear at the power curve peak. And hey, the torque converter locks up half-way through third gear, so it *feels* like there are 5 speeds :-) -- Dennis Nichols '88 WB40 XXV "Priscilla" -- No virus found in this outgoing message.
