its hard to see in the pics, but the rotors are twisted and have a slight bow to them, and go from low to high to low down the length of the rotor, was told its hard to set up to machine them
dyer...8-71 gmWho's blower case is it? GMC never made an 8-71 blower...all those rotors come from 8V71's and the cases are all aftermarket.
Gary Dyer and his son are experts. I think Gary is retired. I sold those guys a half dozen 6-71 cases and rotors several years ago.
Another good shop is Dean's Blowers in WA. Rick Dean did the gas conversion ony 6-71 Hemi blower.
you are right its 15''That looks like a 671.
What’s your blower case length?
15” is 671
16” is 871
if i did take the od off the rotor, whats the worst that can happen...would it make them out of balance or what?View attachment 1715611736 View attachment 1715611737 that 3/8 wide strip is what they call the od its about .005 thick and was told by the blower guys to have it machined off.. would not hurt it at all.
