Hot Rods 671 Blowers

I found 20 busses in a scrap yard with Detroit Diesel 6V71 engines with the blowers still attached. Would it be worth the effort of removing them for traditional hot rods?

 

Yes it would.

 

If they were inline 6-71 engines, instead of the 6V71, then they would. Not much demand for the V type blowers, since they don't have a mounting flange. But if you feel like pulling them off, go for it! someone will want them

 

Like Jim said, find out if they are inlines or V motors. The inline blower is much more desirable. Many bus motors were laid down inlines (known as pancake motors) to save space.

 

Are they free for the taking? Considering how easy it is to find inline 4 and 6 cylinder blowers now, I sure wouldn't think of paying anything for 6V blowers.

 

In the name of "traditional", what did these usually get put on back in the day? Like nailheads or something? Or just, whatever was accessible? I've heard of the 671 blower setups but never seen one in person.

 

6-71 blowers were put on all sorts of big block type engines in the old days. SB Chevys frequently used shorter 4-71's but later on guys figured out ways to get 6-71's on them too. There's probably zillions of old FED's and altereds tucked away with 6-71's sitting on them. Just have to find them.

 

here's one installed in a non-traditional way, but you get the idea. There is no flange along the bottom sides of the blower, so it has funky angled long bolts holding it to an adapter plate, which is screwed down to the intake manifold.

 

The $$$ will really be dependent on the flange for the "V" or non-V.

If you could do the machine work yourself to get them to work on a traditional small/big block gasser and take em to a good swap meet you could make some serious coin.

 

Keep in mind that diesel blowers were intended to be run at fairly low RPM's, compared to the higher RPM gas engines. Serious clearance work has to be done to the blower rotors before they can be used on gas motors. Don't know if any of you have ever seen a 6-71 blower eat itself up. Not a pretty picture.

 

quick look at ebay completed auctions shows 6v71 blowers, straight off the diesel engine, selling for about $100 each.

 

Thanks guys, all V engines on these busses, scrap yard smells money from a mile away he wants $100 each for them, so not worth the effort, too bad. About the RPM, I have a 64 GMC bus, and it red-lines(hits the governor) at a vertigo inducing 2100RPM...
