I suppose that you might be extremely lucky and be at the very far end of the slot and rotation of the pump all the way to the opposite end of the slot might net 10 degrees.

I'm never that lucky.

Even if it did work, you'd have to bend the hell out of the hard lines to get them back on the injectors........a real PITA.

Anyway, align the pump to the marks on the ring and install it at 24* BTDC on the compression stroke at #1 cylinder. It's a lot of work removing the oil filter and all and have oil dripping on you, but if everything else is ok, the little oily saturated sweat you spend is well worth it. A well timed 617 is not sluggish at all and a good one out of time is generally referred to as a dog.

That's exactly what I was going to do. I still have the engine out of the car, so removing the oil filter and the IP is just a hassle but not a real issue. I just wish I did not screw it up the first time.

It was off by exactly one tooth (as predicted). Thanks to everyone for helping.
