chev 4-7 firing order change

MJ, your problem was changing just the plug wires...you also have to change the sparkplugs.

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!!!
