Flipping through the Oct 2006 issue, I noticed the "green carrot" 4104 has a 6v92t and allison 730 trans. Would'nt this bus have has a 6-71 and 4 speed orignally? If so, I am very interested in the details of this swap. Anyone know anything about it?

Very expensive.  You have to increase the radiator size, change the rear end or at least the pumpkin to the 4106 type, manufacture engine and transmission mounts, create a transmission cooler, modify the rear engine door for the extra width.  Like anything else, you can do it with enough money.  Personally, I'd just get a 4106 or 4107/9.  Good Luck, TomC

Keith,
Look in the member section and find Uncle Ned. He owns "Huggy Bear" which has a 6V92 on a transit coach cradle.

His big problem, IIRC, is cracking the inside head.

The 6v92t and allison I have availble locally is in a transit coach and on a cradle, so that is what I was thinking for a swap into my silverside. I know this swap has come with alot of dissagreement in my other post, but I have the gut feeling I can do it, and make it work nicely. I'm quite willing to swap out the rear axle.

Now the big question, why is he cracking heads?

I am the proud owner of the "Green Carrot" and like Tom C said all it takes is money.  While I personally did not do the change over to the 6V92 all of the things stated were done to her.  4106 differential, bulk head modification, larger radiator, engine cover, relocate and increase air cleaner.  It is a shoe horn fit and really runs great but when it is time to do the rack the mechanics hate it.  I don't know how much my engine switch cost but there are a lot of 04's out there with the 92's in them.  Someone on the board should have a close price.  I check this board every day so if I  can help in any way don't hesitate to ask.

Thanks. Your bus is absolutely beautiful.

As for my 1947 silversides, the entire rear is finned, So I'm thinking heat dissapation shouldn't be a problem as much as what you guys are running into. I could be wrong though.

On your bus, is there a cradle, or special mounts adapting to the unibody structure?

Yes, the engine is on a cradle that comes out in one piece.  You can see on page 32 that just to the left of the muffler and left of the air cleaner are two black supports that hold up the back of the cradle.  The front ties to the frame.

On the heat issue, cracked heads, with my big radiator I normally run 180 deg.  but when pulling a long hill in the summer I have to resort to my mister system.  I can keep it at 200 deg. on any hill.  I think misters are a must and they don't cost much.

At the top of the page is a Search box. Type in mister and then click the search button and you will get all you ever wanted to know about misters and then some. LOL
