When I put the 350 in my truck, I also installed the
rear axle from a 1974 Firebird. At the time I was not
to concerned with the ratio since I had 205R14 tires.
Now that I am switching to 275R60 tires, I am
replacing the 2.56:1 gears with a 3.08:1 limited slip
carrier. This equates to 2400RPM at 65MPH. If I don't
like that, I also have 3.77 ring and pinion. (2880RPM
@ 65MPH). Without a 700r, that is too much gear for
highway driving.
When I installed the new carrier with the 3.08 ring
and pinion, I applied the white gear paint from
Richmond gear. Then I spun the gears a couple of times
to check the gear pattern. The pattern does not really
show up in a way that I can understand. Since I was
not happy the results, I cleaned all of the gear teeth
and tried it again. This time, I mounted wheels and
held them so that I really put some pressure on the
ring and pinion. The results weren't any better. What
am I missing? There must be a way to do this.
