THREAD REVIVAL!
This is a question that I wish had been answered, because I am about to dive into this tonight. I just dropped a built L28 into my '72 that I picked up from someone. It already has the ZX dizzy installed and was previously running with this MSD 6AL... I just want to make sure I get the tach right. From what I've gathered so far it sounds like I need the 8920... I've searched through multiple sites and nothing difinitive yet... any input or direction from the gurus?
