Ive got a bunch of roots blowers up for sale. these are right off a detroit diesel, not converted to gas so they must be rebuilt. all apear to be good cores. there is some corrosion but it should clean up with a bead blasting. some spin good. some are a little frozen up. one 671 has no bearings and gears but rotors and case apear good.

list includes
six 6-71 250 missing gear one 200
one 4-71 250
one 8v71 200
one 6v53 150

please do your research on these. THIS WILL NOT BE AN EASY BOLT ON FOR LS MOTOR NOR DO I HAVE ANY MANIFOLDS OR ANY OTHER PARTS FOR THESE






These are HEAVY so take that into account with shipping.. located in central NJ

Correct me if im wrong, but the blowers on detroits were not for boost. They put out 1-2 psi and were used to help scavenge the exhaust gases.
