I don't have access to the specific firing order of LSx. I'll look into it. It may or may not be similar to the little Fords, but it is COMPLETELY unlike any of GM's other engines over the years. The valve "spacing' and "layout" are similar to the Ford, but "opposite". That is, where an exhaust valve is on "front" on one side and in the "rear" on the other, the LSx has the intake on the same side as the Ford does exhaust. (I-E-I-E-I-E-I-E for one, E-I-E-I-E-I-E-I for the other, if installed on the same "side") Of interest, the Ford "W" deck plate bolts right to LSx...
TOHcam,
I believe I'm saying (at least TRYING too...) the same thing, just not as well "worded" as the article. The "turbulence" I speak of as "less" would be IN the quench area, not the overall chamber. It IS true, turbulence in the larger area helps keep the mixture "atomized".
The molecular friction, though, is one of the prime causes of detonation when sufficient octane isn't present, such as in a diesel engine (compression ignition).
