Which blower to upgrade to?
I am really wanting to upgrade my 525sc blower. Right now, I can't decide between a B&M 420 off a 600sc (well used) That is complete with carbs, no chiller. the owner is hoping for 3k. Those seem to last a long time. I think if I decided to let him keep the carbs, I could get it for less $$. I would then put EFI on it. The other Blower is a Holley off an 03 575sci. It has been gone through and includes a chiller. It is the later blower with sealed rear bearings. Those seem to self destruct at 200 hours based on web searches. This one includes the TBI style injectors. Its a complete takeoff with a MEFI 3 computer and harness. I also have most of a 6/71 that needs everything sitting on a shelf. I am ready to do this, but I want the most reliable system I can get. My current set up has been great, I just want a little more power.Please advise.

I have a 6/71 Mooneyham, completely rebuilt by the blower shop. It's got about 10 dyno pulls on it. I'd let it go for $2800 with intake, snout, and carb adapter. Good deal if it'd help you out.

I have a new Weiand 6/71 intake. Unassembled 6/71 with HD end plates It might not be any good, and a new snout. I also have a few pulleys. How long does the snout need to be for a 3V setup?
