I asked if the bearing plate AND snout were interchangeable. They said no. While that answer is perhaps a tiny bit vague and I didn't have time to pry, my guess is they meant, "neither the bearing plate nor the snout are interchangeable." 174s for SBF are goddamn rare to find used. There's only that one in Sun Valley that "looks" like a 174 that I've been able to find. That's after many many hours.

Can you measure the length of the shaft housing for me? Also the length of the shaft itself?

Will do tonight. When you say shaft, you mean the shaft in the housing that actually turns right?

Correct.

Conflicting Information
 

Well, I also asked Supercharger USA:

Do you know if the bearing plate and snout from a B&M 144 is the same as a 174?

They Said:

Yes, as long as they are both B&M's

=============
Anyway, Joe I think you said that's Holley (Weiand) unit right? I don't remember seeing any branding on the unit.

How much would it be to buy the B&M and have the teflon redone?

It's a much smaller blower than the one we have. It would probably be auction price plus at least $500 for full rebuild? That's probably over a G, then the call of the Turbo returns. :laugh:

Yup

Did you get a chance to measure for me so I have them when I go to the swapmeet?

Snout = 11-3/4"
Shaft = 12-3/8"

Give or take a tiny bit.
