I have what I think is (not exactly 100% original, but still unique) idea which requires the case/core of a SuperCharger (a 671, 871 blower)

I don't need the rollers, I just need a the case and hopefully the end plates, does anyone know where someone can find a "blown" blower that isn't rebuildable yet isn't completely split in half. I can't imagine a ruined case can't be worth much, and I'm just going to cut, mill, and grind on it anyways (wouldn't dare do that to a good core/case.)

I have attached the type of blower I need, one with the sides that goes straight down to the manifold. I have NO idea how to get my hands on such a (rare?) item. Thanks.

There is nothing rare about a GMC blower case. There are plenty of bad ones out there as well. Another option is to buy one that is fresh off a diesel truck, they can be had cheap since they are not suitible for street use without modifications.

I would try calling a few blower shops and see if they will sell you a bad core, just keep in mind that they are fairly heavy and shipping will not be cheap.

I see a few on e-bay from time to time.

Here is a list to start with....

If you live near a metro area (can't tell by your "Too Far Away" address), call up some of the heavy truck boneyards. I've seen whole huffers go for a hundred bucks before (scored case or rotors). There are blowers on other GMC motors too...

good luck buying the rear bearing cover.check ebay or craigslist for cases the end pieces are more expensive then the case itself.but thats just me im working on a buget right now and cant just shell out money handsover fist

I'm currently around the Washinton DC area, the car/engine/almost everything is back in Wisconsin.... thats why I put "Too Far Away" for my location, sorry for that. I noticed that the 6V71 and or 6-71 blower has 2 different casting styles, one that curves around to fit better on the diesel engines, and one that drops straight down on the sides like the one pictured in my first post, which has been hard for me to fine, let alone understand which motors they put it on.

I'll start calling some salvage yards for tractor trailers and buses

I don't know what you have planned, bu I assume it's going to be a dummy blower set-up. In either case if you plan to bolt it to a manifold, you don't want a V series blower (6V-71, etc..). All the 6-71, 8-71 blowers drop "straight" down on the sides like your picture.

[MuscleBlock81]

Does anyone know what kinds of diesel machines used the 671 or 871? (not the 6 V 71 as indicated as the wrong blower style) It's kind of going to be a dummy blower, but it will serve other functions if everything fits and I can do it right.

The 6-71 and 8-71 diesel engines used the 6-71 and 8-71 blowers. They are two stroke engines built by Detroit Diesel. The name of the blower comes from the name of the engine they were bolted to. The number designation refers to the number cylinders (4,6,8,12, etc) and the displacement in cubic inches per cylinder (53,71,92,145, etc). So, a 6-71 diesel engine is a six cylinder engine displacing 71 cubic inches per cylinder, or 426 ci.

LMAO!! That really is pretty funny

I won't know what I can get it to do for me until I get one in hand, but I was hoping to fit an alternator and a hydraulic pump ... AND cover a holley double pumper........ within it.... which might make some laugh as much as techinspector1 did, but I want to try anyways.

I know that the 6 means the number of cylinders, and the 71 92 etc etc... but which motors came with the blower I posted in the picture (a GMC 8 bolt blower) and not one of those 2 bolt oval shaped blower? Are we talking about a 1971 CAT dozer or a grayhound bus.... where's the most likely place?

I'm trying to get ahold of guys on ebay with little success. It was a bit difficult trying to find a Big Truck salvage yard around here.

Where do you live?

Blower cases are usually pretty easy to come by at swap meets.

I don't want to rain on your parade, but I can tell you right now that there is no way an alternator, hyd. pump, and a Holley carb is going to fit inside a blower case not even a 10-71. I can go out and get you some general measurement from an 8-71 I have in the garage. You can hide a carb under a blower case and it has been done many times. There's really not that much room in there even with the rotors removed. I know they look big, but the cases are very thick.

The car and toys are in Wisconsin, I'm still able to work out here by Washington DC.

One of my co-workers just made his own CNC machine, (took a cheap mill, made his own circuit board, replaced the screws with ball screws) and I think hes milling some pieces for the mil to make it big enought to mill on the blower, I'll have to wait and see...

The car will fit, I am hoping to maching an alternator into the snout of the blower, (this isn't going to look AS good because the alternator uses such a small diameter pulley.

I think I can fit a powersteering pump INSIDE infront of the carb and relocate the reservoir somewhere else (I have had to take a stock GM PS pump apart to know if I can relocate the reservoir because it look like the pump just sits IN the oil and reservior when just looking at the thing from the outside.

I don't mind someone raining on my parade, it always helps to know.
