I have a roadster with 3:27 rear, 400 x 16 tires and a 26% mitchel. Handles the sierras easily with a few 3nd o/d shirts on the long steep parts. I have a good "touring" engine with police head (5.5)
on my coupe i have an unknown engine with 94 psi in all four holes, 3:78 rear with 36% b/w o/d. I haven't gone over the sierras with it yet, but it seems to handle the coast range rather well with only occassional 2nd over stretches on long pulls. I drive both in the 55 mph range + or - a tad. All 400 x 16 tires, no radials.
