I find this to be very true, ESPEIALLY on exhaust lobes, you see some people specing a single pattern and others a dual pattern with 10º+ more duration on the exhaust for the exact same heads and exhaust with a relitively identaical intake lobe.
I thik the LSA is brought up so much now because for so long it was not talked about. Everyone just slapped it somewhere between 108-116 and called it good. Many old cam advertisements don't even mention LSA, ICL can be adjusted on installation but since the LSA is ground in you would assume people would include it when trying to sell a cam.
And yes Harold and CamKing, you guys are of the few that always have appreciated the LSA for what it is and never over looked it, but you're the bright and shining exception IMO.
And before people jump on this and start talking about when they were drag racing in the 10's 35 years ago they knew about it- most of the posters on this forum are a little more skilled than the typical person who reads those car magazines, the article needs to cater to the majority of its audience, not the top 20%.
