Speaking of firing order... We did have a problem the first time we tried to dyno a set of Elston Tri-y's. They would not fit as the dyno cradle was too wide. The dyno operator said no problem we'll just swap sides and turn them upside down, like a boat header. I told him I did not think it would work.

Well...it did not work. In fact it did not work so well that the engine would not even start!!!

For the record, that was NOT me!
