454 blower

1) I just purchased a 1947 chev dev sedan, with a 454 B&M blower.
2) The carb was a edelbrock, I have since purchased a Holley 850 built for a blower.
3) I found a air leek in the carb adapter plate to the blower gasket which I am replacing.
4) I found that almost all of the hardware was lose on the blower and plate.
5) I was told that my upper and lower wheels for the belt were wrong and the motor was over blown.
6) The blower intake looks like it has been grooved for a o ring.

#2) so I can buy the correct parts how do I identify the size of the blower?
#3) should I go with a gasket or a o ring?
#4) what torque should the adapter plate to the blower be?
#5) the top wheel is approximately 4.5 inches dia. The lower wheel is approximately 7 1/4 dia. I what a dependable boost for the street and a little track. what lb boost should it be? and are the wheels the right size?

454 blower

also I counted the teeth, the top one is 44 and the bottom is 70. Is there a formula to get a 5 to 7 lb boost?

Down load and read the supercharger tech manuals at
Holley Performance Carburetors, Fuel Injection, and Fuel Pumps

Holley/weiand bought out B&M supercharger division.
They build and service al these B&M blowers.

You will find the supercharger size dimentions diagrams
and blower pulley/boost charts.
The amount of boost you can run depens on the fuel octane/ power desired/ engine compresion ratio and spark advance.
blower fastener torque specs are there too.

If you havent done this before stay around 5psi to start. Interchange pullies and tune it in for that level. On the steet with pump 92 octane fuel and a MSD btm, 9-10psi is the safe limit. Many factors contribute and results may vary.

F bird got me on track, when I did the Eforce.

I would use a carb gasket for the carb pad . The blower body to blower base could be o ringed. Then use the line gasket material and rope around the plate groove. Where the ends meet use a dab of RTV.
