Re: Will a 258 turn these wheels?
I have 33's and 3.31 gears with a T5 tranny in my CJ7 258.
If I use 4th gear on the highway, at 65-70 mph I am turning about 2300
rpm. This gives me 19 US mpg. 4th will also bury the speedo. My
speedo and odometer are calibrated right on too.
If I use 5th at 65 mph, it revs too low and drinks gas.
Off road, 1st low is seldom used on our type of trails, I mostly use 3rd
low and climb ravine and sand pit walls, sometimes 2nd low, but not
often. When I crest them, I am turning something like 400 rpm, but it
just powers along. Get too steep, and it will just dig my 33x9.5 BFG
muds in, not stall.
If I do need to crawl, I have no issues about how slow 1st is or I do
know how to use/pulse a clutch without smoking it.

Hi Allen,
I think you'll be happy if you have the 3.73 option:
http://www.4wheelparts.com:80/Tirel_Gear_Ratio.asp Usually there's a tag
bolted between two of the differential cover bolts, if everyone has put
the tag back after changing the fluid.

Re: Will a 258 turn these wheels?
I ran 2.73's with 32's for a full summer when I first got my jeep. It did
OK, but I eventually changed to 4.10's and bigger meats.

Re: Will a 258 turn these wheels?
With all due respect to my esteemed colleague from the Great White North,
I might submit that his Jeep isn't exactly a garden variety example with
fiberglass, extensive engine modification and God knows what kind of clutch.
(I think he might be holding out on us with a stroker engine or some cool,
secret weapon that might put him next on the list after Usama & Saddam:)
I'm not familiar with the T5 1st gear. So, I'll tell you my experiences.
I've a 76 CJ-7 w/ stock 258, T-176 4sp, Dana300 to the AMC20 turning 3.53
gears and braking with 11" drums all around. This is probably a better
setup for "vanilla" comparison.
I originally mounted 31" A/T tires and eventually mounted 33 x 12.5 BFG
mud tires. I thought it was okay at first. I soon saw that the drum brakes
were max'ed and probably overcome by the 33's under hard-braking conditions.
I could lock one rear tire on the pavement about 50% of the time. Gearing
was a different story.
My new clutch was overcome in the first couple of years. Nowadays, I can
spin the flywheel against the clutch in second gear and only spin a tire in
1st on slick pavement. So, I went from the stock 3.53 gearing to 4.10.
What an improvement. On the drive home, I gave it the usual pedal pressure
needed to get rolling around a corner and, BAM!, a tire started howling. I
realized what I'd been missing over the years. The 4.10's bring gearing
close to factory specs when running 33" tires. My mileage has held or
improved.
I'm going to go back to 31" or 32" tires when I swap. With the lifted
suspension and it's high center of gravity, I'm not planning on burying the
needle. I think that the braking will be vastly improved as well.
Someone mentioned a test/evaluation where the results showed that a 31"
tire was the best selection for off-road terrain. Can anybody shed more
light on that?

Hi Jim,
I like your brake drum conversion, far superior braking power,
unless your in an over heating situation, like sports car road racing.
