B&M 174 blower

hello, new to the site, was researching 174 blowers and hope someone can help.

I recently picked up a B&M 174 supercharger ( i think its a 174 ) problem is i have no manifold. and all the research I've done im finding out this supercharger is built for a BBC, im wanting to put it on a SBC 350. i have full access to a machine shop to build adapter plates and such. but just want to hear my options before result in cutting chips.

any help would be greatly appreciated!

Your best bet for a SBC blower manifold would be adapting the intake manifold for the Weiand 177 blower kit for the SBC. You will need to fabricate a adapter plate from 3/4" to 1" aluminum. You may be able to get different length drive noses for your BBC/Ford 174 B&M blower, if nessessary, from shops that service/rebuild these blowers. (Holley/Weiand, BDS, The Blower Shop, etc) The 174 was not used on the old B&M SBC kits. They did have a 162 blower w its own unique intake manifold that was a bit longer than the 144.

The Ford versions had a offset drive to clear the Ford distributor.

you can ID your blower by the length of the case and the mounting bolt pattern LxW dimensions.

fabbing up a crank pulley spacerand longer mounting bolts/studs to reposition the blower's crank drive pulley forward on your SBC will allow you to position the blower in the manifold/adapter to align with the blower pulley and still have distributor clearance at the rear for the SBC distributor.

ALL easier to just sell of the 174 blower off and buy a new complete 177 Weiand SBC kit.
if your used 174 blower is in decent shape, some one that needs a 174 replacement will buy it for their BBC.
thats what I would do.
