Good haul Rusty. If it's not too much trouble would you take some tach readings once you get it broken in? Will you break it in with the pipe or with the stock muffler?

It would be very useful to have some numbers on this engine so that it can be compared to the earlier Blue Heads and the later Square Heads. I have a nice PDP/STS Blue Head and an S.61K Square Head that I will tach with stock mufflers. Then we'll know where everything stands in relation to one another.

Thanks,
David
