Freddie, can a billet aluminium or steel one be made to mimic the original deep groove 3 pulley part? I guess it would need some testing.....although it looks like the other products including the OE pulleys where never really tested!
Also (and I think someone has already pointed this out) surely GM knew about this and put out a better pulley on later Hi- Perf big blocks.....like LS6 454?
