I dont have that book Steve, in what context is LCA used?cjperformance wrote: ↑Thu Jul 12, 2018 9:53 am hi guys,
i am more than happy to be corrected but OP is talking about DV and his rule of thumb deal,
i just re-read how to build horsepower pages 103-107 and DV talks of LCA lobe centreline angle and no mention of LSA thats why i mentioned it as i did in my earlier post, i understand what Walter and Craig are saying but i interpreted as per DV as the OP was talking about,if i am incorrect that is fine as i may of been a bit confused myself

hi Craig,
DV uses LCA in his book as an example
106 LCA rough idle,low manifold vacuum etc
114 LCA smooth idle,high manifold vacuum etc
you and I call it LSA lobe seperation angle
i only remembered it from reading it in his books hence my they are the same reply but after Walter and yourself pointed out in your posts i can see where the terminology is mixed
