i got my new tires yesterday and let me just say these things are beefy

42/15/20 Swamper SX II's


I dont know which one i love more :p



disclaimer...
My truck has a Ford 300 6 in it having drove my last mog with stock motor and 39.5 iroks i dont think the stock motor would turn these tires happily but the 300 6 does well

Of course this post begs a number of questions. First, what did you have to do to stuff 42's in there and second, where in gods' name is the writeup (with massive amounts of pictures) of the 300/6 install? Inquiring minds and all that. :)

Nice ! I to am putting the same tires on my 404.0 Doka, however I decided to have beadlocks made for my wheels. Couldn't find any I was pleased with so I had a local shop laser out some rings. Getting them welded in now. Can't wait til they're done and get the new rubbers mounted.

If the inline Ford works would a inline 6 out of a new TJ Wrangler work? If so has anyone done it or seen it done? I have access to a new TJ motor for $1,000

42's will fit. A bit tight but they will fit. So a 10.5 r20 is 38.5"-39" tall. A 12.5r20 in a Michelin is 40.5" tall. My 14.5 r20's in a Michelin are 43.5/44" tall. The 42's would probably need a 2-3" block for a cab lift and some minor modifications in the pedal and shifter dept.

As far as a Ford Inline 6-300. This has been done before. Sure a TJ engine will fit but you will havet to make your own adaptor/Bellhousing. Don't expect to get much over 40-50mph as usual.

My friend stuck a Ford V-8 5.4litre Triton in his Mog chassis with stock transmission....He of course used a custom built Ford Cab/shortened bed/enlargened wheel housings to fit his 44" under...."Look under Pyro Mog". Custom bellhousing...ect...ect...ect. Had to turn the shifters around 180degrees and back 2'..What do you expect with a Maching Shop Owner with all the tools in the world and aluminum and steel and a workforce to use at will. I've driven it myself. Will do 65mph down the road. Very nice ride. Where's your budget....that's all that matters. He has 80K in his...that's $80,000...But it's his toy....and he likes Ford's!

Just make sure what ever engine you pick you get an engine that has the same length or less and the exhaust/intake out the right...at least the exhaust.

Cheers

no cab lift for 42's they fit fine the way it is. 10.5r's are 36-37" tall. a TJ engine wont work as the intake and exhaust are on the left side. with the 300 6 i can do 100km/h on th gps no problem and at 90 am turning 2700rpm

Those SX's actually should measure out at 40ish inches. So no mods required. Plus your far better off adding an inch or two suspension not cab lift. I still vote for dropping in a modified Mazda rotory in the 404. Speed and power!!!

10.5 r20/continentals are not 36-37" tall! They are 38.5-39"...I've measure my own several times and that's what they are. This is a stock Unimog tire size. Maybe a 404 with 18" rims has a different tire that it uses but the stock rims are 20". Sure a TJ engine will work it's just you need to cutomize your cab a whole lot more and come up with some creative ways for making things work. If you have the time, funds and money anything will work. :thumbsup:

Not everyone has as much expendable cab as others so you always need to keep your projects in mind with your budget. Look at Jekran's 406 rig...How much do you think it would cost you to go out and have a shop make those custom winch mounts ect. If you have your own shop then of course your expense will be alot less.

Rotary engine....I've always thought that a Rotary would be a very good fit for a Unimog...... As far as the 300-I6...It's a good industrial engine. Just depends on which engine you get. As far as rpm's....Somehow this seems a bit off 60mph at 2700rpms with 42" tires. Is there a custom mod in the final drives that's been changed or in the tranny or something else we aren't being told?

the original fuldas on the 404 are the 10.5 r20's and they are definatly 36-37" max. I think you are refering to a modern molded tire

If they are the old mil style that came stock on the 404, that would be just right.

not that it matters but the 10.5r20 contis that came off this rig were 36-37".

Tell us about your overdrive unit? I only say that because alot of us 404' owners would want to know and plus a lower rpm'd engine would work out quite well if it's a moderately priced option/mod ect. Pictures?
