It is not uncommon for the distributor drive shaft on the L226 to be a tooth or so off either way. Rotate the engine until #1 cylinder is at TDC on the compression stroke, take a look at where the distributor rotor is pointing, that is where to plug in #1 wire.
Did rotate and that gave sylinder 1, on the oposite side of where the #1 lead used to be. Tried too start it in that order but now it backfires Just once in one cycle, it doesnt start just one loud bang. Atleast I have spark :thumbup:
The 226 is a bit of odd duck, in that it can't be a tooth off. The distributor shaft is a slot fit with an off-set side.
Your firing order is 1,5,3,6,2,4
Here are some pics. The engine bay pic is from a friends 55 pick up. Note that the number 1 wire is pretty much straight ahead, then go from there with the firing order in a counter clockwise rotation.
It is possible that your timing chain could have slipped but I doubt it. This is a bit of an odd duck as well. If you have the #1 cylinder at top dead center on the compression stroke, the alignment marks on your timing gears need to be 9 links apart. The alignment marks on the gears DO NOT line up with each other.
