All the ideas are good in principle and I study them all.

But do you think the engine could run at 1100 rpm with little misfire, even if there is some, with a cam or an offset igniter?

I can check the camshaft and the correct orientation of the distributor by removing the cylinder head covers and watching that the valves open and close at the correct time relative to the position of the distributor finger. I could also just offset the spark plug wires in the igniter head.

Before, I might reassemble the old breaker ignition system, without the Pertronix box, I just need to redo some temporary wiring to connect the ballast.

Thanks for your help

I know I said I will stay out of it but since your reply was so quick I will answer.

If the camshaft is ground with the wrong firing order, you can not adjust for that.

The valve opening timing is to the piston travel position. If the cam is wrong then there should be some concern for valves hitting the pistons and as a result some being bent.

I don't have a camshaft calculator program to graph the position the valves would be in if the cam is mis-ground but if it is wrong then I'm thinking that only the valves in two cylinders would be wrong and it makes it more likely that your engine can run on only six cylinders.

At this point I would not place a large bet on that scenario but long shots do come in. $20 on a 100 to 1 is a nice prize.
