Thanks Holt!I pretty much tripped over this one while I was gawking at a couple other trucks: The first one is around a '60 Ford(?) panel truck.Very cool,but at some point it suffered an event so violent that it got folded in the center.(In the photo I'm not sure if you can see the big crease in the roof right behind the cab,but it's a mess in person.) The second is what they call a Foremost.Its kind of a truck chassis mounted on an enormous,tracked suspension for Travelling through deep snow where a normal truck would be stuck and buried in seconds.This one is powered by a big ol FE Ford. There are dozens of old Ford pickups up here too,and a Galaxie (Country Squire?) wagon that's not a Complete mess as well.....oh,and I forgot to mention,there's a collector up here who pulled a Chevy coupe (a real old one that looked a lot like an A) out of the DUMP! He also owns an A with a 394 Olds,a bunch of old trucks,a pair of 40 Fords,and I forget what else he has in his junkyard behind the shop. Behind a shop in town there is a '65 Comet four door in really minty shape,and just last week I saw a '39 chevy cruising the river road. It's kind of a gold mine for old cars.Odd,for a place with no roads leading in or out...lol Posted using the Full Custom H.A.M.B. App!
> he 53/71/and 92 denotes the size of the injectors that were in the 6- or 6 cyl engine. Actually this isn't true... The 53/71/92 series represents the number of cubic inches per cylinder. So a 671 is 426 cubic inches (6 x 71). With #65 injectors, the 671 was rated at 238HP. I have a 671 Detroit in a 1970 Brockway I am restoring for my Dad... On a 671 (straight 6), the blower sat on the side of the motor. On a 318 (V8), the blower sat on the top of the motor. I have a few friends with 12V71's, and there are 2 blowers that sit on top of the motor...
Oldspwr:Nice job on that truck!!!!! That engine and the supercharger setup is just about identical to what I was fighting with.lol! I only with I would have known about these when I was younger,and you could still find stuff like this laying around.....same goes for Hemi motors in combines,agricultural water pumps,and boats.

I just went over the photo again for about five minutes without even blinking......the job you are doing on that restoration is just amazing.That thing looks perfect! Posted using the Full Custom H.A.M.B. App!
It is a 6-71 blower off a 426 inline 6 Detroit Diesel. The cylinders are 71 cu.in. times 6 the number of cylinders. That is how Detroit labeled them. You can use that blower, Don't get Teflon seals for the street. The front and bearing plates can be used off the blower, if you reinforce the front with steel rings. If you use the rear plate you might be tight against the distributor. Back in the 50s and 60s they used the original bearing plates. Look at some real old mags, they tell you how they were converted. The rear bearing uses greased bearings and a flat plate to cover rear. photo 354 Hemi on my 32 Ago
That looks perfect Ago. I always loved the ribbed plate on the fuel cars from the 60's. So in your Deuce,how violent is a blown Hemi...?lol! Posted using the Full Custom H.A.M.B. App!
Read you were taking apart to get it home, be aware you have to pull the gears at the same time due the helix of the gears and the spiral of the rotors. Been a while; but I seem to remember using two steering wheel pullers, worked good for both the gears and the end covers. I took a couple of pictures of one of my old Detroit manuals to show what I am describing. Note: the rag stuffed in the intake to hold it from rotating without damage.
Rich: Thanks for the tip!I may end up just biting the bullet and shipping it home assembled so I can work on it when I have plenty of time... Posted using the Full Custom H.A.M.B. App!
Blown Hemi in the 32, 7 psi boost. Not bad, stick shift car. Gets real scary real fast in 3rd gear. Ago
That sounds like fun! I'm going with a B&M HydroStick I scored from a fellow HAMBer recently...I hope they are as violent as everyone says they are...!lol! Posted using the Full Custom H.A.M.B. App!
Before you take that blower apart you should mark the timing gear set. There is a L.H. and R.H gear and at least one side will have a set of shims behind the gear. I would also check the rotor and case clearances to see where everything is for a base to work from. If you don't know already, there is a thread posted on here about how to rebuild and set the timing on a 6-71.
Hey, partner. You are the closest location to me on this particular thread, so I need to pick your brain about something, and should not have so far to drive if you have something I may be able to buy. I have a flathead Ford/Mercury/Lincoln 3 sp. trans, top shifter, with an overdrive tailshaft which resembles those found on '49-'53 transmissions. The stick is not offset like Lincoln shifters tend to be. I would like to know anything about it before I spend time/money unsticking it. Would fit nicely in my '40 2 Dr. Thanks for any help. Anyone else have anything to add ?
An old guy( I use that term with respect!) I knew(R.I.P. Johnnie) used to rebuild GMC blowers back in the 50s and 60s for Chris"The Golden Greek" Karamansenies and others. I axed him what he did to make his blowers so reliable and good for hotrods. He said "Go EXACTLY by the G.M. manual!" I figgered he had some special clearances or somethin.....R~R
I'm finally going to pack the thing up and send it home on Monday....pretty sure Im going to be getting all my gaskets,bearings,and parts,as well as an instructional DVD from deanblowers.com His site looks pretty comprehensive.If I feel like I'm getting in over my head I can just call somebody more experienced to finish it up,but I would really like to learn how to work on these.

Don't be afraid of working on these blowers. Just take your time and do a little research on them. As a little time goes by you will realize that these units are really not that hard to work on. That's what I did five years ago and now I've practically machined one from scratch.
This morning I found a 4-71 too,but I won't get time to retrieve it til later this month. When it rains it pours! Posted using the Full Custom H.A.M.B. App!
Got the 6-71 home and on the bench,going back for the 4-71 next week. Posted using the Full Custom H.A.M.B. App!
Cool story on the blower. I worked at a Terex dealer when I got out of votec about 26 years ago. I was able to work in the rebuild room and rebuilt a few of the blowers. They are a piece of cake. You need long feeler gauges to set the clearance and 2 pullers. We went through 12v71s, 16v71s all the way down to the 53's. The 53 blowers didn't even have bearings in the end plates, just used the aluminum of the plate like a bushing. Tell you what, you here a v-16 full load and rpm on the dyno it makes your hair stand up. It almost sounds more like an electric motor!!
Those rotors must have been whistling like crazy! I remember standing at the big end of the track one Friday night when a Willys ProMod car was making test passes...the blower was so loud that after it passed the 60 foot you couldn't even hear the exhaust,it was just this scary whistling noise that just kept getting higher and louder...It was pretty cool experience.
