no not relly. primary length is a fixed number - then it becomes a packaging issue. 4-2-1 is an attempt to reduce interference from whacko firing orders the v8 gets per bank in a 4-1 collector (the poor mans 180deg header) - not sure of the real word benefit of 4-2-1 vs 4-1, its certainly debatable
perhaps my pic above is a misleading angle? theyre not THAT long. 33-35" overall primary length. some swear by the magic number 32", i calculated a bit longer, rms' engine is longer still. i think the 33-35" range is about spot on
mos? sleeping i suspect
