(I may have had an epiphany in the shower this morning and answered my own question, but here goes) I have an LSX454 GM crate engine and am putting on a Wegner front drive system. Part of the changeover entails removing the factory crankshaft pulley and replacing it with an ATI Super damper. I was able to remove the factory bolt OK but before trying to yank the pulley, I was looking for the keyway or some other method of indexing the damper to the crank, and didn't really see one.... So before I yanked off the old one and then lost the relationship, I thought that I would ask here.
Now, in the shower this morning, it struck me that maybe my geezer was kicking in, in that the only reason that one registers the damper on a SBC is so that the timing marks align at TDC so that you can adjust the timing by rotating the distributor.... So it occurred to me that with a computer-controlled LS engine with coil packs, there is no practical need to know where TDC is with regard to using a timing light, because the computer will know where it is based on the crankshaft sensor and the timing is going to be adjusted with a computer, not a wrench and a timing light.... Which would lead me to believe that the new damper can just go on any which way.... Yes? Thanks.
