The diff I just removed has the same tapped holes. It has a 30 count splined axle.

Hey OT, if you like that one, here is one from a fellow from northern Manitoba.

OT, I think mine has about a 3/16 hole. You'll be able to move a lot more sand with a 5/16 nozzle, but you also need the compressor to sustain that amount of air at a good psi. The higher the air PSI, the more force the sand will have to remove paint

I agree with KPM. The 300 puts out 170hp at 3800 rpm. The wooden machines weigh only 3400 lbs and having the same track and ski area as my r18 at 4600 lbs is a big advantage that you have.

I have thought the 350 motor/ transmission in my old 93 chevy 1/2 would be a good combination. 350 have good horsepower and the 4 spd auto with od would give you that option when your on a good hard pack road. I just didn't want to go that route just yet being that my 318 and 727 tranny are pretty good. Maybe the 4.56 gears are alright in an industrial engine ( I understand that they have better low end torque), but I believe that my 318 came out of a 1/2 ton truck and it needs some rpm's to produce horsepower. I ran across a horsepower curve chart once (I haven't been able to find it since) and if I remember the hp at 2500 rpm is 120-130. Peek Hp (230) is at 4400 rpm. When breaking trail, I'm lucky to get 2500 rpm, and will pull down to 2000. Under 2000 rpm it really pulls down fast then where I need to shift to first gear. I can get all kinds on rpm in 1st gear, but speed is too slow that I rub snow along the belly pan which is getting close to being hung up and stuck.

They really are a neat machine, a nice size for cruising, and this one looks like it really good shape. Good find.

It looks really close, but mine axles have 30 splines. There are 3 types of Chrysler 8.75. Mine is the 741 casting, using a 1-3/8 dia pinion. There is a 742 and a 489 case which have different dia pinions.

What vehicles have a dana 44? It looks like the dana may be easier to get different gearing and different types of locks or limited slip. There is another diff lock made by Ox. This locker uses a cable to shift in/out. Might be better than the air locker for air leakes etc.

Pulled the differential out today. It is a Chrysler 8 3/4". with 4.1 gears, so adding 20% I should need about a 4.89. I cannot find a diff lock for it, so I may look for a different diff. that I can get a locker for. Any suggestions of what I should look for?

Hey Bigbud, do you have a tach and speedo in yours? What kind of rpm do you get at 25 mph?

I have a 318 with 727 auto. It goes good down a packed snowmobile trail, but it really struggles going across fields. I'm hoping to change that for next winter.

A ford 9" was installed in it prior to me purchasing it. I'm missing about 20% in rpm's. I'm thinking that it's about 3.5. I haven't pull it out yet. I haven't decided what I should put in yet. I can either get 4.11 or 4.30 or a 4.56. I was told that factory gearing in those years was 4.11 and later years were 4.56. I don't know if the 4.56 came out when the 318 auto was standard issue or not. KPM had a bomber with posi and he said that it was real good so I'm thinking that the air locker diff could be the ticket.

I was doing some reading and it seems that may not shift until the diff oil is warmed up. Possibly the use of synthetic oil would be beneficial. I have to pull my diff out to change pinion and ring gear to a different ratio anyway as well as new seals and bearings. It would be the time to try it if I decide.
