Subject: FTE Perf - Stress on ring/pinion at high rpms?

Looking for anyones input on this idea I've been tossing around in my head ...

Looking at running 5.13 gears (in Dana 60 front & rear) with 33" tires. At
highway speeds, coupled with a .68 overdrive (Tremec TKO), the engine (300
six) will be turning 2000-2100 rpms. Thus, the ring and pinion gears are
going to be spinning pretty darn fast at that point. With the use of
synthetic gear lube, is there any danger of abnormal wear and tear on the
differential guts during prolonged highway travel with this setup? after
x-thousands of miles?

power transmission is a function of rpm and torque. if the same power at
the wheels, then a faster spinning gear set will have less actual force
applied to the teeth of the gears. although the teeth on a larger
(numerical) gear are weeker the actual bearing surfaces should see less
force applied. the faster rotational speeds = more power loss and possibly
higher oil temps in the diffs, but with synthetic oil i see no problem.
although i hae heasrd of some people finding rust developes sooner inside
diffs with synth oil, i have not noticed this myself yet.

i personnaly see no problem as long as they are street gears, not racing
gears, and you break them in properly according to the manufacturers
recommendations if they are a brand new set.

BTW, if that 300-6 could pull it, with that overdrive you will be seeing
125 mph at 4500 rpms. and in top gear still crawl along at a relaxed pace
of 40 mph at just off idle.

Joe,

I am not to familiar with any performance upgrades on a powerstroke, but i do
know one thing. I take the muffler off that thing and just "weld" in a
straight pipe you'll get a better sound and better running engine. My
neighbor did it to his truck and you can even hear the turbo "wind up"alot
more. (less backpressure).

Everything you always wanted to know about Powerstrokes and maybe some stuff
you didn't:

Subject: FTE Perf - E4OD vs. 4R70W

Last week someone posted a link to Bauman Engineering's website. They have
lots of interesting info about the E4OD, 4R70W, and the AOD.

The site is; http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.baumannengineering.com/index.htm

They mentioned that you can tell the difference between the E4OD and the
4R70W with a tape measure. The pan on the E4OD is 20" long, the 4R70W is
just under 15" long.

Bauman builds a black box that they call "TCS" which allows the E4OD to run
without the EEC-IV computer. I am interested in hearing from anyone who is
using one of these or similar products from other companies. I'm toying
with the idea of swapping a E4OD into my '79 in order to gain the OD.
Anyone else out there done this??

later,
dale c
'79 f150

Subject: FTE Perf - Re:AOD trans, which one?

I'm looking to drop a 351 in my 57 F100 and because of the 3:70 gears I want
to use an automatic OD trans. My question is which one and what year should I
use, no racing, just an occasional trailer to pull. I'm gonna be running a
carb and no computer, and I want the simplest way out. Is there only a
kickdown cable and a vacuum modulator to worry about like on a C4 or is it
more involved than that? Thanks, LOBUCK
