Ok,this mite have been addressed but could not find anything when I did my search.I am putting a 351w and AOD in my 79 yoda,not going to build it up just bone stock with a propane kit.I was just looking for good of idle low end torque only a v8 can deliver,and going ford because I like the sound and the way it Idles not to mention I happen to have a 351w sitting in my garage without a home.
The question on my mind is,How long will my stock 4 cyl 3rds last if I dont abuse the truck?What could I do other then replacing the intire axle to make them hold up to the v8?

Exsperiance tells me I will snap the 3rd before the axle or pinion but I was looking for some insight from poeple that have done a v8 that could tell me how long there stock set up lasted.thks in advance.

Your not having fun if you dont break something!!!!!!!

 

just swap a ford 9" rear.. itll pay off better on the long run.. and you could stomp the skinny pedal when you wanted..

 

So your saying to put a 9" in the rear,what about the front,do I need to put one up there or does it not matter?

How about this,Can I swap the 3rd member out for a stronger one say like a v6 or swap in a dana 44 3rd.I know it wont bolt up but got a welder and can weld mounting bolts on to match or have a shop do it for me.Any body have a suggestion other then spending 2-4 g on 9" rear and front?

 

you could try a V6 third.
Alot of guys run V8's through toyota axles without any issues.

also, a 3rd from another axle won't work in a toyota axle, lol.

toyotas are 8" carriers, so putting anything bigger in it would require a larger housing.

 

maybe a v6 rear axle and a d44 or 60 would manage.. but youd have to be easy on them.. is the windsor built or what?

 

Its a stock motor rite now,233 hp, I am planning to put propane on it so I am going to build it to propane specs witch includes upping the compression,but my plans are to keep it stock.The power a stock motor puts out is a hell of a lot better then what I can squeeze out of the 20r I have and if I am going to start swapping motors around I am going to do it rite the first time,like I said before I already have the motor in my garage.Its the off idle torque I am going after.Not planning on racing the truck just having fun off roading.

There are quite a few 85-95s runnin Small Block chevys through toyota axles with no problems.

 

I see a lot of v8 conversions,but a lot have changed out there axles.I'm not willing to give up my narrow wheel base.I guess it would depend on how hard I run the truck.I just don't want to buy lockers for my stock axles and then have to replace the axle when I brake it and have to buy another locker for the replacement axle.

 

So is there anybody running stock axles with a v8 installed in there truck that can give me some incite as to how long or if there axle have held up to the 8 cylinder?

 

ppl ran it, but snap axles in least desirable places
