    Any input from you folks that have used this blower? How does it perform?with a built 502? What size is it, looks like between a 10 and an 8-71???

    got a couple buddys that run them on small blocks in their street cars. 350, iron heads, 14 lbs of boost and a 150 worth of spray! 800 hp and has been running it for 5 years with only one rebuild on the blower.

    Still runnin strong on a 548, 16 rib marine set up. 5psi . Over 100 hours no rebuild, no noise. Should start thinking about a freshen up by now. By the way 420 is a reference to cubic inches wich would make it a 6-71, Seems to perform like an 8 though!
