Ok I'm new to Chevy restoration Ford and MG is what I have a better grasp of.

SO I have a 51 3600 with the original running gear, not a bad thing it runs good except it has no brakes so going to have to put modern brakes on it.

I'm fairly sure it has the 4.57 rear end and it has a 4 speed.

Is there any thing out there to convert the stock rear end to a higher ratio ?

Then there is the modern rear end option what 8 wheel bolt one will fit best, 250 Ford C20 Chevy.
Or just go to a F150 or C10 and swap the front hubs to match.
The goal is a driver to replace MY S10

I've heard you can go with a ford ring and pinion from a 87-93 econoline that will fit. My notes tell me to look for ID E5TW4210BJ which is a 39/11 for a 3:55 ratio. This might be what I look for also. I have a 3600 with the same basic set up.

If you want to keep the 8 lugs, you may want to update your brakes to Bendix type. I believe yours will be Huck type. Although you can get your shoes relined and new wheel cylinders, new drums are almost unheard of. Correct me here, everyone, but I think 53 and later had the Bendix set-up and can be retrofitted to your axles.
You can find a 4.10 center section which will bolt into your current rear, or go the replacement axle route to get an even lower ratio. I would suggest getting a bracket to install a dual circuit master, either way, so one leak doesn't take out all your brakes.

Try a Dana 60 from a mid-80s to mid 90s Dodge van or pickup. It'll get you a 3:54 ratio, 8 lug wheels, modern brakes. The most critical measurements are backing plate to backing plate and axle tube diameter. I put a Dana 60 from an 87 Dodge 2500 pickup into my '59 Apache. It was 3" wider than the stock rear, but it fit fine, axle tubes were the same size. I had to shorten the drive shaft ($120), buy new u-bolts ($20), and a new U joint yoke ($30), and get an adaptor to reduce the brake line from 3/16 to 1/8 ($2).

The original gears were 4:56, and I would run out of steam at 55mph with a V8. Now I can hold 70 all day long.

There are a few different options out there. Some guys will tell you to do a 1/2 ton drivetrain swap, while others will say go with the MII frontend, late model rearend. I'll tell you what I'm doing.

On my '54 3600 I've obtained some front rotors and calipers from an '07 Chevy 2500 van. The rotors slide right over the the original hub. The caliper fits and clears everything, I just need to finish making the mounting brackets for it. I'll need to plumb everything and get an updated master cylinder too. BTW- I purchased some roller bearings (not ball bearings) for the front, and I have Ford van rims. The rotor and caliper won't fit in oem rims and some later model rims.

Onto the rear; If you can find a 60-72 3/4 ton center section, you may be able to get a 4.10 or 3.90 gear, but alas they are HARD to come by. Like other posters have stated, Dodge and Ford vans have a narrower rearend option, along with the Ford trucks with the Sterling rearend (Not Dana). Chevy has a 63" WMS (wheel mounting surface) 14 bolt rearend that they used in Cab and Chassis applications that is fairly easy to come by. You can get gears all the way up to 3.42. I just recenty purchased one and plan on using it. You can find some posts made by myself and Grigg in the Ton's O Fun section.

Go to www.photobucket.com/whitedog76pics , if you want to see some of my progress on what I'm working on. I'm planning on updating the pictures too, so keep checking back.

Well found a 3.73 semi-floater out of a 89 2500 chevy nice big brake and with the extra inch of off set of the rims planing on using it should fit.
We will see in a couple weeks hopefully

Good job on your find. It looks as though you didn't need our help after all! LOL

If I remember right, the semi float axles are around 65" WMS. It should work pretty good. The 3.73 gear should improve your cruising speed dramatically, without taking away the low end.

For your rims on the back, try to look for some Dodge B3500 rims. In my junkyard exploring I've found that they have a little more backspacing. For the front rims, look in the Ford direction. The ones I have on front fit perfectly.

Well had to ask if there was any easy way before going the swap it out for a modern rear axle every bracket they put on it will have to come off.
The F250 rims have 4" off set compared to the 3" on the stock rims, LT235 16s sure fill up the rear fender LT216 16s might fit better

The new rims will also be wider than the oem rims, hence the need for more backspacing. I've heard of guys saying you can't use any more than 3.5" backspacing, but I didn't have any trouble. Right now I have 225/75/16's mounted on the truck. They fit real nicely. They are only about a 1/4" shorter than the oem 7.00/15's and the footprint is only about 1/2" wider. I have a set of 245/70/16's that came off of my Trailblazer, they are noticably wider, but about the same height as the 225's. I may just put them on the rear though. I don't how they will be with the armstrong steering. For easier steering some guys like the 215/85/16 tire, the only bad thing is that they only come in a kidney busting load range D or E.

Checkout www.photobucket.com/whitedog76pics ; I have some rim and tire comparisons. The 245's aren't mounted on a rim and inflated, so they appear a little shorter in the picture.

Change the differential center out of a '67-'72 3/4 ton automatic trany truck. It is a direct bolt in to your axle and has 4.11 gears.
