blower question? for b&m High energy

I have a blower question? for b&m High energy blower.

Does anybody know what size it is? It was a kit that PAW put out in late 80's It was a kit that went with a 383 stroker with a B&M low profile hi energy blower. Does anybody know what size this is? How much boost it has & anything else that would help set this back up. I have the whole setup except the blower is broken (snout is bad) I can use any info about this setup. It was advertized at 486 hp torque was almost the same within +/- 5% of hp. You can e-mail me at ****************

Thanks guys!

I today run a Weiand 250 SBC blower, essentially a 4:71 in swept volume, and previously ran on a SBC 355 a B & M 142/144 blower. That dates back to the late 1980s. The B & M I used is, again in swept volume, basically equal to a GMC 2:53. Inviting other commenters to correct me if I am wrong, my memory is that Weiand, now part of Holley, bought out the B & M blower series sometime in the later 1980s or early to mid 1990s. Given that history, if my memory is correct, today's Weiand/ Holley should have info about the Performance Auto Warehouse (PAW) marketed product you describe. One thing for you to check: how many lobes are there on the blower rotors ? Again inviting others to correct if I a wrong, designs based upon GMC "53" series blower had two lobes on each rotor , while "71" series blowers had three.

You should get plenty of responses on the board.
