Truth be told, I haven't checked into the 8-71 -- the 6-71 has to be available. It's the most common of the GMC-type blowers.
That GMC blower works 'cause it's sucking air down through the carb and picking up fuel, versus blowing "dry" air in under it. Actually improves the dispersion of the fuel/air mix as it's spinning through the compressor rotors.
460. Now we're talkin' arh arh arh arh. There is no replacement for displacement, as they say. I've never built a big block, so I'm not sure if blowers are interchangeable big block to smallblock. Much bigger difference in the distance between heads and ports. I'd call the folks at Weiand, or one of the other manufacturers that makes that type blower.
If you do talk to them, you should check all my info on blower interchangeability -- long time since I sold that car.
