Vintage Blowers and Drives

I havent gotten the motor togeather yet, waiting on my crank.
BUt it loks just like the magazine article

 

I'm not exactly sure of the history of the GT bearing plates, but I think they were one of, if not the the earliest one piece aftermarket rear bearing plates. I think they were available through and may have been a part of the Cragar line?

 

Here's mine. The blower drive belt runs behind the water pump. I used two water pump extensions to space the water pump out from the block and made a mount to set the alternator forward. The bottom pulley is the gear drive with a home made pulley made from a large chunk of aluminum bolted to the front of it to drive the water pump and alternator. Manifold is a Wieand. No idea where the snout came from.

 

gotta bring this back up, iam starting my blower project, would love to see some more pics of whats out there............

 

Walden Speed Shop is repopping the log Cragar drives for GMC blowers.

 

Do a search,"Got a new toy, vintage supercharger stuff" there are photos, links, and links to other blower threads. I just bumped it up to the front page for you.

 

Any body have those old magazine ads on drilling front of heads?

 

Alot of early blower drives used a chain...yeah...scary as hell for shure!

 

This is from PHR mid seventies. I have that issue.

 

Bought my 6-71 off a guy in MO on craigslist couple of years ago. He had it on his boat and when I got it I thought nothing of the case.

Just recently found out about Pete Robinson . . .

 

Does anyone have pictures of an isky blower driver on a sbc not from an isky catalog? Thanks

i have a 4-71 and would like to build my own V-belt drive, are there any threads of this? i have searched a few times with no luck.

 

I used a currently available snout and idler arm but whittled my own v-belt pulleys.

Here are a couple of threads that you might find interesting.

Here are a couple of pictures.

 

Still curious about this. Anyone ever turn up anymore details or pictures of this crazy thing?? Never seen any others.

 

Stupid question. I think I know the answer, but always wondered...

Why do/did front-mounted blowers use two tubes instead of one large one? Was it done for the simplicity of construction for the tubes and intake manifold? Or is there some other reason I'm not thinking of?

 

here ya go rory, hope this helps...

 

Helps a lot thank you

Personally, I would not want to be responsible for someone's dismemberment if my chain drive broke, and that's anywhere... car show, on the street, anywhere...
If it were me, I'd only use the chain drive for a static display only.

There are reasons why they stopped using this kind of stuff!

 

That's bad ass looking.....seems like i've seen some of that before?????

Did it work out for you?

 

I can't believe nobody has posted a pic of Howard Cams chain drive set up.

 

sure did; i used an adapter to run an isky drive pulley on the water pump (instead of the smooth isky water pump pulley)...shouldn't have any trouble with the belt slipping.

thanks again for selling it to me...i really appreciate it.

Imagine from the driver's seat it would look a bit like driving a Bridgeport down the road...

 

I've never run a Bridgeport before but if it's like driving an old supercharged car it must be a kick in the pants.

 

It's a modestly-sized machine tool.

 

Your setup looks good. Looking forward to seeing it in person this summer

 

I know what they are,
I also know there is no comparison at all other than the blower shown above is set verticaly.

it's like saying my horizontally mounted blower is like driving a metal lathe

 

That shit is overrated...

 

thanks jeff...

 

Was going to wait to out these up but I've been bored lately. Still waiting for and idler pulley but I will most likely end up machining my own.
