B&M 250 blowers
 
Nice set of polished BM 250s. Bought these for a project and went a different direction, under ten hours on rebuilds according to previous owner. Water passages look good. BRAND NEW Holley 1050 dominators on them. 4800$ for everything, includes v pulleys and blower pulleys for crank. Will sell for 3600$ without carbs. https://cimg7.ibsrv.net/gimg/www.off...89297e6e59.jpg

Sorry, they fit shortdeck bbc, rect intake port.

Great price to get in the blower game. I run this same set up on my motors. Single carb jetted properly yields great AFR results and is pretty much dead **** reliable.

GLWS!

Thanks jamontes, curious to know what engine you ran them on, and how much power/boost you made. I've heard 675hp is possible with a hp500 and 6lbs of boost. That's good reliable bolt on power.

These still avail?

I would be all over this deal if someone would buy my number six drives

Gen 5 540's... Yes, the 250's are a bit small running 4lbs. 90/94 jetting 6.5PV in the carbs. They are an old Nickerson set up.

Idle at 800 and AFR's stay around 11 - 11.5

Navy bought them last night so they are sold. Carbs still available. Did you ever Dyno your 540s? How much boost did they make on those big engines?
