Question about LT4 balancer hub
I can't respond directly to your question because I didn't go the same route as you are.
On the 388 LT1 I just installed in my 96 I went with an ATI Super Damper, part # 917274. I came with a spacer and thick washer.
I installed a new reluctor ring and the damper spacer in front of the Cloyes Timing chain I bought from Summit.
After everything was installed, from looking at the two engines sitting on engine stands side by side, it looked like the ATI damper extended farther forward than the stock setup.
So I measured from the exact same places on each block to the fore-most rib on the damper (388) and the for-most rib on the stock pulley.
the measurements were identical. I didn't want my belt to run at an angle, so I was relieved.
So even though the ATI "looked" like it extended farther forward, effectively it didn't.
Hope this helps.
Jake
