I Need a 3.40 pulley I think the part # is 155173 ? I can't make out the # clearly

B&M is now a Holley company. Your local automotive high perf shop should be able to source this for you. If not, the Blower Shop can. They are now Holley's supercharger repair/warranty authorized dealer.

i had 5 of them i let go with my 250 when i sold it. now i have a 420 megablower.i bought another pulley from teague,they make there own pulley's i guess for the 420's nice and shinny,where you been??

just happen to think about,teague was running a special when you metion oso they gave you a discount,i ran into this you can buy a bigger bottom pulley i think your's is like 6" something in diameter,you can buy a pulley for the 420 thats bigger than your bottom pulley and use your same top pulley and run more boost that way and i bet that the pulley is alot cheaper than buying one for the 250 powercharger.if you want i can call you and or fax you the pulley part #'s.dave

Erick at the blower shop said they do not make that pulley size any more. I'll just have to run more boost until I get one. Dave I have been around. How have you been. I was up your way in the DCB PM your number.Tom
