Ok Ive read this thread over a few times. I'm a simple construction worker, so please keep this in mine. The A2 spicer has a 5th gear ration of 1:1. The A3 4th gear has a ratio of 1:1. The A3 has bigger tires, so why doesn't it go faster? Is it the axles that are geared differently?

The spicer 3052 used behind the gas and early multifuel was direct
The spicer 3053 used in the later multifuel was overdrive

Ok I dont know where I got the 3053 being 1:1. So my final conclusion (that was summed up in about post number 2) is that getting the 3053 back in with the same tires or bigger would give you a better top end without the OD kit, or would you still need toms OD kit?

you wouldn't need the OD kit, because the 5th gear in the spicer already HAS an OD gear.
If you REALLY wanted a taller OD gear, then you could do both, but MY Cat3116 wouldn't have the balls to push a truck along with gearing that tall. It barely climbs the hill leading up to my house with the Allison auto in second gear

Thats a good point, you do put the 3053 back in, how will the engine act at that lower RPM say at 60MPH.

even with the spicer gears, if you keep stock tires, 60MPH is going to be near redline anyways

the 3116 can be turned up to more power than the multifuel. with a stock 3053 you will have some more mph, but not much. with gear kit you will have 67 mph at 2500 rpm. there is a mph/rpm charton the od gear website for comparason.

Has anyone come across additional information on compatible transmission or other options to obtain more speed out of a M35A3?

see post #48, a flywheel for the 3116 is just over $200 new. i think it would be an easy swap.

Tom, Are you referring to post #48 of another thread?

no, i am refering to this thread. most OD trans are just that, OD, while the 3053 with my gear set is more like another gear which is what is needed with such a low rear ratio. i am very surprised no one has done this swap, i think it would be the best of both worlds.

Ok, I understand now. I was just confused because post #48 didn't mention a flywheel. If I was to go back to a Spicer I could also install a PTO/Winch. Starting to sound more and more attractive. My next step though is to talk to a local transmission/diff/gear shop to see what ideas they may come up with.

keep in mind that no one has ever found a trans with this much OD that will fit in the short space available. given that you would spend, $3000 doing this, (a guess) it would take some time for payback, but driving at 65-70 is much nicer than 48.

Is that 3k for parts, or 3k for 'all done'?

parts, you may be able to do it just a little bit cheaper if you already have some of the parts like the trans and clutch. life aint cheap!

I must just be an "old fart" now,'cuse life is pretty sweet at 45mph! When I want to go faster I drive a different truck, pretty simple.
Slow down and enjoy the ride, life is about the journey - not the destination.

I hope to take my A3 from Atlanta to the family farm in south Georgia multiple times a year. The trip is 240 miles which means that I could make the trip in about 1.5 hours less time (each way) if I could travel at 70mph. I would rather take that time and use it around the farm/river/ponds than to use it absorbing the scenery along I-16 (I have made that trip hundreds of times and there is nothing along that route that I haven't already seen or care to see). To each his own though.

If you plan on turning an A3 tire at 70mph, be prepared to be a dead man.
