Damper diameter...
My stock damper has an 8" outside diameter.
Many replacement dampers for SB 350 have smaller diameters, beginning from 6".
Logically, a smaller damper should be lighter and give the engine a higher acceleration rate. But what about its efficiency ? Is it as good as a bigger damper ?
What harmonic balancer diameter do you have guys on your SB ?

A SFI 18.1 damper is highly recommanded in this case. But it seems to be difficult to find a 8" SFI 18.1 compliant damper.
Most of them are smaller. And here we go again !

Stock H.P. dampers like the GM one on L-82's are actually rated as good for dampening in a lower rpm motor.
I use all SFI 6 1/4 one motor has a FluidDamper and the other an ATI.
My original l-82 broke it's rubber ring before 50K miles. My shift kitted small block just tore it up and they are dangerous.
