Anyway, will borrow an advanced timing light to night and give it a try. here

Aligned notches with advanced timing lamp set to 8* yesterday, went smooth, the engine now runs more smooth. (Entered base mode with a jumper between black and black/white first) here

Today I increased the timing by turning the distributor until it started again. Then I measured it, and it read 29*. [links]

[AbbР№BenoРѕt]

Checked also normal mode with light set to 0* - and the mark on the balancer went maybe 5 mm to the left looking at the front of the engine. Sounds right? [links]

My problem is that the manuals don't state this clearly, and I'm getting different opinions. Thanks for the reply anyway. What would be the effects of running at 0* ? more

All American V8s have offset cylinder banks to accommodate side-by-side rod pairing on the crank throws. In the absence of published information, the number one cylinder will almost always be the one that is farthest forward regardless of which bank it is on.
