From what I read a tighter LSA will sacrafice low end TQ and a wider lsa will smooth out the idle and add more TQ down low but lose HP/TQ up top.
I was simply asking if my cam was gonna suck on the street do to the 107 lsa.
I thought i comprehended it pretty well! You start speaking chinese in every post and nobody except a rocket scientist understands! Just because you know what your talking about..... or maybe you dont, doesnt mean everyone else does.

Ok smarty pants, why dont you try to help rather than be a dick! Im not a cam genius and Lloyd Elliot picked my cam. So thats my starting point. Now rather than throw out a bunch of **** nobody understands, you could be more helpfull Like James & post graphs and explain instead of talking smack. I clearly stated it was my fault for not reading that right and there you go again!

I posted a link to valuable information on the subject, probably the only useful information in the thread.
You just got your panties in a bunch because you put your foot in your mouth proving exactly what I said about working on your comprehension. Sucks to be wrong but man up and learn from it.

I learned and clearly said i was wrong. I did read your link but that also probably had me more confuzed than anything! If it was LT1 specific it would of been more help!
Sorry dont mean to be an ***. I was just asking a simple question and it seems you tried to make me feel stupid for it!

Seems to me that people are getting too caught up in LSA, when the key ingrediant most are searching for is actually overlap. The difference between the 112 and 114 is basically non existant. IF it was me on a N/A build and I had to be in the 224/230 duration range I would calculate how much overlap the motor needed and depending on that I would chose the LSA since the duration would be a given. Something around a 108 would most likely be optimum on a 355-383 ci motor. Depending on the CI, overlap needed would actually need to be changed to compensate.
Duration and LSA go hand in hand with Overlap.
Just for example, by just relying on LSA "MOST" would say that the camshafts below have the same overlap. Where in all reality the 234/238 has much more overlap.
224/230 on a 113LSA
Vs
234/238 on a 113LSA
I pretty much read just about everything David Vizard publishes, and popular hotrodding had an article about camshafts from him. Pretty good read.

224/230 on a 113LSA <- 1* overlap
Vs

LSA is simply a measurement which will allow you to calculate the overlap.
You don't want to compare cams of different duration using the LSA as your only guide.
This particular OP was asking about the 224/230 cam.

dayum. I don't understand why someone would spend more to go down on power. It cost that person more money to make it less powerful, than just buying a hotcam and calling it good. Imo that was not the best way of spending his money. I have a custom grind CC503 from Bret Bauer, it has a real nice chop with a 108 LSA and .565 .568 lift. 
I love it, especially on the top end. I agree tho, sell it so you have no regrets.

I'm confused. When Caprice is talking about no starting point, does he mean we need the stock specs to compare? I'm confused by what he's saying - I'm a cam newb.
I thought it was pretty obvious we were comparing the CC503 on 114 LSA and 112 LSA. But maybe I'm misunderstanding.

People want to talk about LSA and what widening it or tightening it does but are referencing data that assumes a proper starting point and 112 is already really wide. Again read the article I posted. Vizard is a pretty good resource for the average enthusiast, there are guys that know a LOT more but are also not so willing to share it with the public.
112-113 are appropriate sometimes for emissions but if doing it for a smoother idle you should instead be picking a smaller cam.
I should say that T/A KID is right that LSA is not the important number, overlap is.
