I have to totally agree with Ramm.In a small block I tried a 196-196 104lsa in at 104 vs 204-214 112 in at 107 cam they idled almost identical,but the 204-112 was heads above in power, but my point was you have to take away duration to clean up the idle(overlap) so you are giving up power/rpm.Also in another build with a tighter lsa I had more reversion and had to retard the cam to clean it up.Comp wasnt the first to build advance in a cam , I think it was crane (could be wrong but it wasnt comp) and their thumpers arent all that bad for what they were intended.YR seems to want to always create a **** storm and pound his chest to prove himself correct and some see through it and some dont . I dont really agree a tight lsa is the way to go. In some cases they also need more converter better exhaust,more comp,better intake and for the street with a dual plane full exh. low comp your shooting yourself in the foot not to mention worse idle,carb issues.You cant have both.Almost all if not all of these builds are street not race only.
