Projects No spark from coil, no start

Here is what My rear end looks like, do I have to find one that is EXACTLY the same as this?
Or will a 3/4 - 1 ton 4.10 that is oblong work?

(not sure if that's the right description for the one in second pic) Just trying to figure this out, thanks all.

Added second picture as example to what I meant.
Thanks

 

You might be able to find a Dana 60 like the one in your pic that will swap. There is one in a '70 Chevy right next door to me. There are 3 things you need to know.
The distance between wheel mounting surfaces.
The distance between leaf springs.
The width of the leaf springs.
The overall width needs to be close, the last two need to be identical, and you may still have to modify your driveshaft.
If you want a for-sure bolt in deal, you will have to look for an HO72, and swap the center section into your truck. Do you know how to pull the drive axles out of your rear end?

 

Since I just got done putting the rear end back together, I'd say that's a big yes. Lol

And yeah I would like to do a straight bolt in swap, meaning the differential, not the entire axle.

Mine is a Ho72 and a 4.56 gear ratio, I'd like to find one (and think I might have today) in a 3/4 or 1 ton 1960's era truck.
It has the exact same housing as Mine so I am hoping when I crack it open it should hopefully be a 4.10 ratio.
I don't think I want to go much higher than that.

Just off the top of My head, how much difference rather than doing a 5 speed swap would the rear end swap do in My favor?

Keep in mind that I am still newbie on this,..

If I can get her to go faster just by putting a 4.10 in the rearend and save time and money rather than doing a 5 speed swap and have to change the e-brake setup and who knows what else etc etc.. then I will be happy.

My biggest issue is the hills and mountains here in Missoula are making her crawl like a baby, and people honk and flash lights or high beam Me instead of understanding that (hey she's an old rig and doing the best she can).

Thanks in advance

 

You need a bumper sticker that sez - "I May Be Slow, But I'm Ahead Of You!!"

That'll get ya fixed right up.

 

Lmao, Now that's funny right there!!
Thanks, that made My day

 

Just remember, if you are powering out on hills with 4.56's, you are going to lose more power going to 4.10's. Meaning, if you can't maintain speed with what you have now, going to 4.10's will only make it worse. That 235 has limits, and it sounds like you are right up against them. Are you ready for a V8 yet?

 

Nope, I like My old I6, as I have had them before, and I think they run better than the V8's.
Thats just My opinion though, and I think should use less gas than going to an 8.

I'll figure it out and get it to where it needs to be.

Even if I have to wait til we move, and then once we are set up tear into it and do complete rebuild.

I can tear the engine down, refresh and rebuilt it and see what that will do, just ideas I keep thinking about

 

4.10 versus 4.56 is 10 percent. I think. So the same RPM you get 55mph with the 4.56 will get 60.5 with the 4.10

 

Oh, ☹️
Hmm,.. what about a 3.73?
What I am trying and hoping to accomplish is the build up the mpg as well as keeping some torque for hauling boat and or camper. (Not a lot, but ya know)..

Anyway, I just want her to move a little smoother faster and still keep some power/torque.. I thought 4.10 would accomplish this, but if I need to go higher I guess I could.

Thoughts, Ideas??
Thanks

On a side note... I am running the original 7.00 - 18's on this. Not sure if anyone is factoring this into the equation as far as mpg and mph that I'm trying to get as well as torque for towage.
Thought I should add that as I'm not sure if it might help.

 

Hope everyone is having a blessed weekend. And want to thank you all for your advice and comments helping Me with My rig. I really appreciate all of your help.
Thanks folks

 

The higher you gear it, the more power you will lose. Our old trucks are never going to perform like newer ones, unless more power is installed under the hood.

 

Well,..
I want Mine as original as possible, but as long as I don't devalue My baby I might consider a bigger engine... But that would really take some thinking and mulling over cus I think I can do the 4.10 and keep My stock engine and still do fine.

I decided that unless I can find a 5 speed that I can keep My e-brake setup as is that maybe I don't want to do it after all. Unless I can regear My original transmission to update the gears.. idk if that's possible at all.

 

To be honest and not trying to be an ***, old truck are just old trucks, not worth much, mine included, a bigger engine will make driving it way more enjoyable which is what it should be about!

So, a bigger engine and leave the trans as is and the rear as well?

Will that keep it as a powerhouse and still haul a tank down the road if so desired?

Like I've said, I want to keep optimal torque as well as speed her up, and keep the e-brake as original if I can.
What I would like to do is turn her into a working daily driver, and keep her looking awesome doing it!

 

If I were in your shoes, I would look for a small block chevy, and a V8 bellhousing up to and including 1967 (6 cylinder from 1963). You will need it because yours will not fit the sbc. You can buy reproduction motor mounts, they can be had in a kit that comes with frame and engine mounts. You will also need to change your throttle linkage, a later model pedal with a cable is easy. I do not remember if your flywheel will work, but if not, the correct ones are easy to find. The truck with the rear you were going to look at might have the bellhousing and ***ociated parts you need.
You can also put a big block in it, but you will have to fab the front mounts for that. Back to the small block. Headers for a 73-87 4wd will work, this I know, and maybe earlier ones also. A 350 and the 4.10's will give you a truck comparable to a late '60's to mid '80's 3/4 ton. In my mind, one with a V8 would be worth every bit as much as a 6 cyl. version, unless we are talkin Barrett Jackson material. If you put a V8 in it like the factory did, you can always put the ol' 6 right back in. GM built them with V8's, not one ounce of cutting/welding or butchery is needed.

 

Hmm, now if I did anything like that I would need something non invasive that would not alter My truck in any way, if I can find a bolt in V8 as you said (like factory did) and still keep My trans and driveline I'll be happy. Otherwise I will keep it as is for now.
Once we move South I won't have to worry about the hills so much.

Anyway thanks for the response

 

Today I found a V6 and a V8, I'm thinking of maybe buying to take with Me and rebuild at a later time when settled after we move.

Which is the best option, as I notice the throttle linkage is a bolt in option for both these trucks that I looked at.

The way they are setup, the throttle linkage that is in My truck should work also.

All in all I think I might like the idea of the V8 as it will give enough power to tow with as well as hauling heavy loads when necessary.

I found a transmission that has the same e-brake setup as Mine, and I believe is a 5 speed.

These are making My mind work and think about which I should do more than the other.

I like the thought of the trans more so than the change in engine.

Let Me know what your thoughts are and why you would choose which one more so than the other.

Thanks in advance.

I love all the feedback and advice from everyone, you are all very helpful and I learn a lot here from everyone.
Thank you

 

Need to know more about the transmission, get all the numbers off of it that you can find, and some pics are always helpful. Personally, I would skip the V6, having had one in a 1990 1/2 ton. Good on gas, but not much else, and certainly not for towing in the mountains. A stroked 350 (383 ci) would probably make you the happiest, easy to install, and lighter than your 6 too. Anyhoo, see if you can get more info on that transmission, I think there were 5 speeds in the larger truck and bus department.

 

I'll know more tomorrow

 

I'm with Mr. E. 100% on originality. Our 55 Belair 235 does great as is, Mother In Law (rip) bought it new. It is what it is!
I would enjoy that truck as is, put a bed on it, paint it. Keep it under 60mph.
If you want more power, buy a newer truck as a second one. That imho in the long run would save all the h***le, and all that time and expense would pay for a newer second truck.

Found a 2 speed rear-end, might do a swap for that and make this a real work truck.
I would love to put this ol' girl to work and show it off at the same time and have fun with it!

Still thinking about My options.

I did find a transmission, as I mentioned the other day that is like Mine with the e-brake setup and is a 5 speed. Might still like to get one of those and do the 2 speed rear end swap and keep My original trans and rear-end to swap back some day or even put into another rig.

As I said, still thinking about My options cus anything is possible!

Hope you all have a blessed day

 

Ok, so I found a site that offers an overdrive unit.
Can anyone tell Me the pros and cons of these?
Are they practical/ reliable and would this be what I am looking for to get My truck up to par?

I am strongly thinking of building it into a recovery wrecker and doing some repo / slavage work.

I had a lot of fun doing that before, and I think it would be a cool way to make some $$$ while looking good doing it.

Thoughts??
Thanks

 

Which overdrive are you looking at?
Which wrecker bed are you thinking of using?

 

Well, I have to get some pics of the trans cus it's in My boss's garage. And the overdrive is built in, so is bonus.

I'd like to see if I can find an older vintage unit with twin winch, I believe called a sling truck.

What I've always called em anyway.

But other than that maybe Holmes or Chevron?? Idk yet TBH

Could also possibly build one..

Just kicking the idea around for now, but pretty much any GM style wrecker bed that will fit and function.

Oh, the o/d unit I saw online was not what I thought, so I dumped that idea

 

Took those pics of transmission today, .. here they are.
It's an NV4500 W/ E-brake

 

Im not real familiar with the 4500, but the 3500 can be used. The funny thing with those is it is easier to adapt the Dodge version than the Chevy.

 

Well, from what I have read online, and heard from others, the 4500 is supposed to be stronger and will take more pounding ( not sure if they mean torque load or abuse) than the 3500.

So, should I be looking at Dodge trucks rather than Chevy for a trans?

That sounds a bit odd to Me. But stranger things have happened.

 

Yeah, we are getting way off hamb freindly here I think. Google nv3500 in 55 to 59 chevy truck and see what you will find, there is some info out there. I thought about an nv3500 in mine at one point, so I could keep my original transfer case. The biggest stumbling block is the fact that Chevy changed the bolt pattern on the transmission with the later transmissions, and the input shafts are longer, I believe.

 

Hmm, ok.
I'll have to look and see what I can find. I'm not comfortable mixing breeds of trucks, I want to keep Mine as much as I can to originality as possible.

I'm not sure what the difference is between the NV3500 and the NV4500.
I am thinking that the 4500 is what I want for towage and work. Not sure about the 3500...
I'll see what Google says about them both.
Thanks
