i was thinking about a 4 speed "brownie" that wouldn't to hard or really expensive.

Your truck weighs about 11k empty and you tow heavy, so it makes sense for you.

Yeah, and I get these ideas in my head that keep me up at night, figuring them out, until time and money allows it to happen.

When I was three years old, I swallowed a handful of rusty bolts, and they lodged in my head.

I built an 85 CC chevy with a first gen bolted up to an rto 610 with a divorced NP 205. Initially I didn't like it. The hardest part was finding the right slave cylinder. Now that I'm starting to get the bugs worked out I love the truck. It's taken some time to get used to the trans but I can start in as high as 5th with 37" tires but I'm going to regear it to allow me to use the lower gears.. I really only use half of the gears. I did not put a body lift on the truck because I hate them but I did have to modify the hump and my gas pedal but it looks great.

I know I am asking for a lot of information but for future reference do you have a listing of all the parts that were required to attach the RTO610 to the rear bare block of the Cummins engine? In other words if we walked into a big truck wrecking yard what big truck would we be asking for to remove the parts from?

Other than the bell housing, everything else was fabricated. All cross members and mounts were made for the truck. I would strongly suggest that what ever tranny you use, try to find a driver side starter bell housing. Mine isn't and I had a heck of a time with the exhaust. Also, You need to be careful of the torque that ou could potentially make. I bent the frame and had to box everything and get the frame straightened.

i had an 8.3 cummins in a 2000 F650 with a 10 speed and a 3 speed brownie .
i installed all of it,the truck came with a 3126 cat and 4 speed allison.
the 10 speed gets old fast,none of your friends can drive it etc.
i used my truck for my work,but i would never do it again.
its slow shifting and just not worth the trouble.
my 85 Dodge crewcab has a 5.9,4 speed allison and a 3 speed brownie,its a great truck.
i have a 6 speed allison to go in it.

I would consider that a big PLUS.

Where would be a good place to find a brownie box? I would like to find a 3 speed one with a low, direct, and an overdrive. Thanks

I would also like to know. How heavy are brownie boxes?

Just about every old style rear-discharge cement-truck had an auxilliary of some sort, with most being four-speeds.

I got mine out of an old air-rotary well-drilling truck.



With the advent of the air-shifted RoadRangers, the use of auxilliaries started to fade away.

If you find one now, you better grab it.

I know that this is a open ended question but what do they usually run? Would there be enough room for one on a single cab?

why does anyone want 8+ speeds in a pickup truck? It might be cool, but come on...its a pickup truck, not a semi. You dont need 8 speeds, your not pulling THAT much. a 6 spd might be nice sometimes, but really.....

I drive an 18 spd all day, and shifting 6 times in the first 500 feet gets old quick. sometimes i wonder....first stacks....now 8 speeds/10speeds...whats next?

Whats next you ask?? 24.5's, jake brake, I agree it isn't fun shifting all the time. But we should not discourage him if he wants it. We all like diffrent things. They shift so slow. 0 to 60 would take all day.. I will stick with my 727.
