Yeah, I need to get skooled on cams too, lol. I am liking what I read on the MS4, but I don't know how to determine what LSA I need. I just want a fun, sloppy and nasty sounding cam, lol

My setup:

04 LQ4
LSA/863 (LS9) heads
LT Pacesetters
ORY
Flowmaster CB (no cats) Might go with a true dual
Patriot Gold kit
LS3 intake
90mm TB
M6
MWC Fab 9''
4.11 gears

I really like the MS4 so I think I am going to go with that, but like you were told, I read from some that you would need to flycut your pistons, but TSP said that is only if your heads are milled IIRC. This is just a fun temporary cam for me till I get my Turbo setup complete so all I want is something that sound like I should be in a Slayers pit moshing to, lol

I found this on another website while searching Google for info on how to read cam specs; I hope it helps you out a bit, it did me but I am still confused, lol

:

The 224 means the duration at .050 on the intake, 234 is the .050 dur. on the exhaust, .525 and .550 are the intake and exhaust valve lifts. The 114CL could mean either the intake center line of the cam lobe is installed 114 deg. after top center or more likely it is refering to the lobe serparation angle which is the angle between the maximum lift point( or center) of the intake lobe and the max. lift point on the exhaust lobe. A wide LSA like 114 usually gives a broad power range, smoother idle, and increased high rpm power. A tight or lower LSA usually like 106-110 will usually give better low and midrange power but is more "peaky" and comes on with more of a bang but the higher rpm power falls off more quickly. A tight LSA cam usually has a rougher idle due to increased overlap( given the same cam specs except for the LSA change) and does not make as much vacuum as the wider LSA cam. Intensity if found by subtracting the .050 duration from the advertised duration. A 270 adv. duration with a 220 .050 duration would have a hydraulic intensity of 50. Another modern fast lobe cam might have an adv. duration of 270 but an .050 duration of 230 or have a 40 intensity. The lower the intensity number the quicker the valves open and close as I understand it. Am sure there is a lot more to it than that but gives you some idea.

BTW, you have another thread up asking the same thing. Not sure if you double posted by accident or what, but you may want to delete that so info can stay in one place - FYI

Hey check this out, it is a program from Comp Cams that you can DL for free. You plug in your cars specs and it will give you the right cam for your setup. Not sure how well it works, but it's a good starting place.
