Recently, I posted a thread about a cam I purchased on a whim and got a lot of great answers but also new question that really needs a new thread.

I have the chance to swap my original cam for one a little smaller but since I am cam spec reading illiterate will someone please tell me the difference between these two cams and how they will perform. Goal is 400 RWHP and a stuck in traffic driver with a MN6 trans. Both are from Comp

Cam A. 228/228 .571.556 111 LSA
Cam B .232/240 .580/.580 113 LSA

I know there are a lot of people here who can just look at a cam spec and give a good estimate on how it will perform so hopefully one will chime in.

Thanks

both look half way decent, but I would go with http://texas-speed.com/p-1148-texas-...-camshaft.aspx

One has more duration on the intake and exhaust and more lift. It will also produce more power at higher RPMs.

that is the cam i was planning on going with but i ran into these for less than half of what the 228R is running. guy bought the 232/240 one and decided he wanted to go forced induction so he changed it out after 5K miles

The big question though is, which one will be more drivable?

Generally, a cam w/ a larger Lobe Separation Angle will idle smoother and have better manners in traffic conditions. I ran a TR224 on 112deg LSA for years in stop 'n go traffic with no complaints, just as a data point.

cam B will drive better. if both lobes are equal

really, even though the bigger cam has more overlap, the wider LSA will be easier to drive? thats cool. Going on a C5 LS1 that is getting LS6 intake, AI heads, and long tubes. I guess I will keep Cam B and pass on Cam A.
