The Stovebolt Forums Forums The Parking Lot General Truck Talk Tranny or rear end??

Thanks for the replys. I was told that this is the best board on the net and it is.
I really don't have $1200.00 to spend on the gears, bearings and shims and some labor that I need so guess I will drive along at 42 miles for awhile.
Thanks again
George

Before you give up, what size tires are you running? I run tall 16" on my 1 Ton with the 4.10 rearend and 60 mph is not a problem.

This is a no brainer,change out your rearend to a better ratio,maybe a 3;42 or something even higher.A tranny aint gonna do you any good,cause most of them are 1 to 1 ratio going to the rear.The only exception would be an overdriove unit,which would be somewhere around .78 to 1 going to the final drive.

I'd swap rear gears for something more along the lines of a 3:73, this should be a good compromise gear.

If your going to use the original 216 I'd be cautious of a 3:55. The truck could turn into a miserable machine, underpowered. As mentioned a 3:73 or 3:90 may be better.
Good Luck

George, any opinions concerning whether or not your 216 can pull 3.55 gears are pure guesswork unless they are from somebody who has actually made that conversion.

I converted my '36 Chevy pickup from 4.11 to 3.55 gears and I'd by glad to describe how that worked out for me if you're interested. The '36 engine is even more anemic, 207 cubic inches.

The actual conversion is in an article with a lot of pictures of the machining and welding on the 1936 Chevy Owners forum.

my email is rwaldbaum@aol.com

the only problem with 3:72 or 3:90 gears would be the only other option is 3:55 gears if you want to keep the torque tube, thats all there is. 3:72, or 3:90 gears don't exist. unless of course you can get rickmg to tell any of us where he got a special set made that is your only choice.

I was wrong on the power glide rear gears. The catalogs show the 355 aftermarket gears fitting 37-54. The power glide gears must fit just the cars.
