Laying over

[Adger Smith]

Rob,
That is good info from your engine guy. I was headed that way. He has increased the cyl pressure. You might need to close up the plug gap a little if you are running it pretty wide. I have found that big cu in engines with 18 deg heads don't like a lot of timing. The plug is located in the chamber high and close to centered. It doesn't need a lot of timing to get the flame front over the dome and get pressure rise. I would also use a non extended tip plug with alky and that head. The wet alky /air mixture hitting the hot exposed extended tip could ignite before the spark.
Good luck with the tune up.

One more thing.. How old is the fuel cell? Does it have the foam removed?
If it had gas in it and you went to alky the foam could be deteoriated and loose it's shape and be pulled over the inlet, cutting off fuel flow.
