G5x3 requires no flycuting on a 112 with stock heads. Why would lsa determine whether or not you fly cut? I thought it was lift that determined if you flycut?

X3 on a 112 will fit but is very tight and flycutting is recommended.
The LSA/ICL will change the VEs, therefore changing Int. valve opening and Exht closing which could then interfere.
Lift has nothing to do with PTVC as it occurs close to BDC and not TDC where problems arrise.

Would run this with 59cc AFR 205's and would also be interested in the LG F-body headers I've heard about.

AFR 205 heads have more clearance after getting milled to 59cc than a stock head. Your unmilled heads will clear by an even larger margin.
:sarcasm: I'm sure Lou is glad everyone has taken the time to read his informative posts, rather than continuing to ask the same questions over and over again. :/sarcasm:

The only thing I am unsure of is...Why does the G5X3 cam cost $50 more than the MS3? I'm about to pull the trigger on a cam, but I can't justify the $50 between the two cams.
Also, here are a couple dyno sheets to give you an idea of the differences in power between LGM's G5X3 and TSP's MS3 (both stock heads):

What people are missing is that Lou Gigliotti's LG Pro Long Tube Headers "the most powerful header on the planet" makes the biggest difference. When you add Lou's headers vs some of the competitions headers that is where the biggest difference becomes obvious. I am very glad I went with LG's cam and exhaust, but wish I'd have went with the g5x4 and stayed cam only. JMO FWIW ![Devil](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_devil.gif)

But what happened to my other post? I had another post after the one you just quoted. I am just curious as to why the LG cams cost $50 more than the next competitor's cam?

I'm FAR from an expert, but here's my take on why LG cams are a measly $50 more:
Because you can charge more when you put out a quality product that people will pay for. And because of the years of research. Well, that and the fact that they charge extra for profit, of course. I've seen lots of cams locally and the G5X cams are very good cams. Most who have seen them run are willing to pay the extra $50 for the performance. Have you ever seen how well these cams perform, up top and down low? They don't have the bottom end sacrifice as badly as most competitors due to the extra timing. I decided it was worth it after seeing a few friends run them and seeing their power curves which helped me decide that it met my needs. And since cam manufacturers grind in extra timing (and I've even heard of other features although I don't know enough to comment on them) it can be hard to make an exact copy. So for me, I was willing to pay the extra $50 to get a cam that I watched do what I want a cam to do, for sure, instead of taking a chance on a custom ground guess, or a competitor whose cams I hadn't seen enough good from in person. I'd seen LG cams (the G5X2 and G5X3) perform well enough to trust their cam.
We used a degree wheel and a dial indicator to measure all the dimensions of my cam when we put it in, and I'll say that the measurements were to accurate that LG obviously has stricter quality standards than other manufacturers. I have 2 buddies with the same name cam from another maker, and there are widely varying measurements on their cam cards, showing that some companies aren't as strict about what they'll accept from Comp's grinds.

Hey bro, that graph should be Jim Sharp's car. It's a C5 ZO6. Not the C6 Z. Anyways I agree with you on the 50 buck difference. Worth every penny.
