Hey guys I am gonna starting assembling my 408 stroker in a few days and have been looking at some new cranks. I seen that some cranks have different reluctor wheels. Why? Why do some have 24-teeth and others have more? Whats the difference? And which is better? Thanks!

You need the reluctor wheel that is appropriate for your particular ECM Early LS motors use the 24 tooth reluctor while later models use the 58 tooth.
