Got a question here about the vibration dampers on chevy small blocks. If the power used to drive the blower is getting up a bit or if there is a severe backfire, it tends to fail the stock damper by either striping the bolts out or splitting the casting.

Now either you can get the aftermarket dampers that are stronger. Or as I have heard (read) you can get a steel hub that replaces the damper and drives the blower bottom pulley directly. Weiand used to make them, I think. Either they were for street or competition.

What I am trying to figure out is does this apply to aftermarket internally balanced 383 chev stroker cranks ? Is the blower belt going around the bottom pulley enough to soak up the resonace (vibration) that the crank is putting out at high revs ? I's for a street strip fun car.
