Raylar camshaft lobe seperation
WebOct 16, 2009 · The reason race cars have that rough idle is because the engines used are designed for high-rpm operation. To get the air/fuel mixture in the engine and the exhaust out at high rpm, race cars need a camshaft with as much lobe lift and as many degrees of duration as possible and a narrow lobe-separation angle(LSA), which results in valve … WebMar 24, 2006 · The different ranges that work are depend upon port flow, CID, rod/stroke ratio, and several other variables. This part is true, that as any engine's cam goes from a WIDE LSA to a tighter LSA, the torque curve goes from flat to peakier. In 350s, wide is 112-114, tight is 104-106. In 454s, wide is 114-116, tight is 107.
