LSA Question

Go to Don Terrell's Speed Talk and read the conversations with Mike Jones (CamKing, thanks Hysteric!) and David Vizard and study the 128 cam formula. They say that LSA has the most effect on peak cylinder pressure during the combustion cycle and that one degree of LSA is equal to at least four degrees of intake valve closing event. CattledogGarage has some videos where he talks in depth on the subject and cover it in better detail. He also gives the formulae for rocker ratio and compression. It takes several veiws to filter it all but it's worth watching.
