Does this prove David Vizard's 128 lsa formula ?

I get that as long as it's degree'd it should be fine... i just worry about everything and being 6* off was just bothering me, wanted to know if it is a known thing that happens is all :)
Sounds like your good to go.
Probably not. In-line wedge heads SUCK at overlap and that is what matters. You get overlap right and you can get VE’s in the 110-115 range. That makes power.

Of course, I’ve been told here that horsepower doesn’t matter and 300 is plenty so this is all mental masturbation.

I might add that that thinking is bullshit. In 44 plus years I have never had a customer say to me “I want less horsepower” unless it was an engine that was built for one thing and they want to use it differently.
Exactly!
I pulled my Larry Shepard book and my 2005 PAW catalog books to do some LSA (Centerline) comparisons based upon this discussion thread. It seems that the trend is to use a 110-112 LSA for street or mild competition and a 108-106 for maximum or modified competition.
As was previously mentioned, this is old knowledge that is still valid today for these type of engines.

The 110/112 is fine for street drivers not concerned with anything but a nice easy driver. 112 is really good for that. Now if your throwing away torque due to the LSA being wider than optimal but like the smoothness for your car and driving style, then it all doesn’t really matter.

@273 DV supplies graphs and testimony. He has more time in the dyno rooms **** house than you have been alive. If his writings of what he did are t good enough for you then please by all means start dnyo testing your own engines and camshafts.

Let us know how it works out.
