I went to set the timing on my 88 5.0 ho, I found much debate online, but eventually found this excellent wrote up - Distributor Stabbing and Operation
anyway, my balancer doesnt have a 10btdc mark as I switched the wp rotatoon, as a result I had to mark the balancer on the other side with an older 289 pointer on the cover.
So I figured id stab at 0 and then dial it in..
so I stabbed it at 0, with the trailing edge of the arm and the leading edge of the stator blade as directed in that article, and the mark on the dist base and block aligned, because I guess that mark was there for the factory installers, I may aswell use it.
The interesting thing being that when I came to time it, spout out etc, it was already at 10btdc.
The article says to set your balancer at 10... I used 0...
I double checked my tdc mark with a tdc gauge and dial indicator, its bang on.
The only thing is im using a dial back light, would this make any differemce or are they ok on later engines?
The engine runs well but shakes, the shake is consistent and gets worse with revs, im guessing imbalance somewhere.. if my timing light is misleading and im actually still on 0 / tdc, that wouldnt cause detonation would it?
