CC503 112 LSA vs. CC503 114 LSA
So I bought a used cam from a member on here, and after talking to Greg Rollins at CompCams, it turns out the cam I purchased was a custom ground cam with the same specs as the CC503, but with 114 LSA (the normal CC503 has a 112 LSA).
What will be the difference between the 112 LSA and the 114 LSA? Any noticeable HP differences, RPM differences, etc.
Thanks guys.

You really wont be able to tell a difference I doubt but for peace of mind just sell it so that way you have no regrets later on just my .02 If your going for a smooth idle though then I would keep it but if you want the idle of a typical 503 then you won't be happy.

This is failing to consider that 112 is already MUCH wider than optimal. So are you saying if he went say 120 on it, it would have diesel manners, massive lowend and no topend??? The "rules" folks want to apply to things like spreading the LSA have to be consider from some starting point.

112-113 is common for emissions, but 114 NA not right of this application.
One of the Impala guys tried a 116lsa cam because he thought it would be good for nitrous, was a failure on and off the bottle.

what im trying to say is with 112 lsa hes going to raise the powerband over the 114 lsa which will give it smooth idle and more lowend torque verus the 112 lsa im not saying 114 will have diesel powerband and 112 is going to have a 4.6 4 v modular powerband

Increasing the LSA on that cam will cost you power from 3000rpm and up.
By 6000, you're down 10hp.
A 116LSA has even more negative impact on the graph
I like the 224/230 grind in a street car with a 350, I just prefer it with more overlap.
That doesn't necessarily mean it would be a bad N20 cam (in fact, the N20 grind would be very similar)
It would however make it a lousy blower cam LOL
Whereas the 116LSA cam described above may have been better suited to an FI motor.
You'd give up the benefits of overlap in exchange for the ability to trap the pressure built up by the blower.

If you have any type of emmisions where you live, the 114 lsa should allow you to pass easier as well. But like everyone said you will sacrifice a little on top end but will get a little more out of the bottom rpm range.

When you tighten up the LSA, your basically tightening up the torque curve & increasing cylinder pressure, thats with everything else staying the same on the 2 cams, i like a tighter LSA myself, it gives you a much stronger mid range, of coarse it will be choppier the tighter you go, & of coarse it depends on how you install it too, if you want to lower the torque curve, you advance it, if you want to move it up, you retard it, i'd say if your not too worried about the sniffer, get one ground on a 110 LSA, you'll love the way it feels & sounds, Loyd Elliot just changed one of theres over from a 112 too a 110 & gained 5 rwhp & 5 ft lbs. of torque, it used to be there 224/230, now its a 223/230.
