after drooling over MBHD's e-bay ad for the supercharger again, I still have this question,, I understand (i think), some s.b.c. dampers will go onto an inline,, I thought I read that someone has grooved a sbc damper to eliminate the need for a pulley,, If I didn't imagine that could one be grooved for a serpentine belt,, or is there a sbc damper with no pulley, already grooved,, I thought my 96impala lt1 was that way, but I cant find a picture that close to tell,,in my 65 chevy II there is no clearance for a pulley,I have now a 2 groove balancer that is about 1.5" from the bottom rad tank,,,,the fan is spaced so the blades just miss the belts by 1/2" and the fan 1/2" from the first core,, tight,,
