: Critique my cam selection

The cam I will use will be a Comp Cams 224/230 115 on XFI lobes and is very good durabilty wise with the dual springs I use. I have yet to have a failure, knock wood. On a couple of C5 Z06's I have seen 430+ RWHP with this cam, but I would expect in the 395-415 RWHP area as we are using cats, stock exhaust and a less efficient differential. Not quite the same as a C5 Z06 here. Should still be a lot of fun.

This is what my tuner set me.

So its a 224/230 with a 115 LSA on XFI lobes.

My requirements were streetable camshaft built for reliability over power.
Kooks 1 3/4s with high flow cats and an k&N intake would be the only other modifications at this time. Heads down the line.

Thoughts?

Do you have the lift figures for this cam?

224/230 will be fine... id assume lift is around 560+ which will be good for breathing, the 115 will have almost no noticeable lope though. Well, it will sound like something is done to it, but more of a "woopwoopwoopwoop" sound. If you want people to KNOW you have a cam(and fear you lol) get a 112 LSA or 113 LSA. Youll be producing more grunt with the lower lobe seps as well.


Ill put it this way, I was looking at something like a 234/236 .589/.593 112 LSA (2k plus power range, really really angry idle)

Your friend is duration over lift...I use to have the GT-11 cam with 215 231 lsa of 117 and .600+ lift for both. I got the NAF cam and my numbers are 222 228 118 LSA and with .58x lift. My idle is Smoother, and my power comes from idle up...I just need to work on the tune slightly so i get better milage and less surges...

If i were to swap out the 1.7s for 1.75s i would be PERFECT, but YT dont make 1.75 either 1.7 or 1.8 ONLY...No worries, what i dont make on power i save on weight...

Just get this one and be done with it. 239/242, .649"/.609" 111 LSA. Its what I had but its not as streetable as you would probably like. lol

NAF cam FTL , 428rwhp with i/h/e/cam/ud pulley

FTL????

My cam is smooth, no lopie idle, and in traffic its very calm...

I am pushin that much or maybe more...I have CAI, FAST 90/90, GMPP HC heads, Cam, UD pulley, Headers, HF cats, catback, and LS7 flywheel

So your GUESSING that your making that much lol, Yea Stock heads, stock Intake manifold/TB here.

I like my lope and i can go 40-50 in 6th with no buck.

Thanks guys, sorry I don't have lift numbers. I assumed there was some information to be taken from what I gave you.

I appreciate the input yu guys have given though. Need more research!
I told my tuner that I drive about 15-20k a year so reliability over performance and that I am going to be running poly mounts so I don't want to be shaken to death.

Well last time i posted numbers i was THE Jester...People laughed their hearts off....

So i prove myself on track times not dyno numbers...Gonna hit the track here then if i feel rich enough V-Day III, but that is in the plannin stages still...

Even with my big cam on 111 lsa with the poly mounts, my car didn't really shake much. I was disappointed.

I would be too. If I didn't drive a Cadillac...

And thoughts on the use of XFI lobes over some of the other lobes?

So is that LSA kinda too wide?

My cam has XFI and XE-R lobes. XFI's are more agressive. LSK's are even more so. That just means that the ramp rate is higher, and the valves open and close quicker. As long as you get good springs it shouldn't be an issue, especially if your lift isn't outrageous. 115 LSA is going to give you a more stock sounding idle, which may or may not be what you are going for. I have an LSA of 111, and it lopes medium-hard.

If I were you I'd spend the 25 bucks and get a custom cam spec'd by PatrickG, so you can get exacly what you want, spec'd to your exact needs.

Finally I wouldn't listen to NAF on this. Definately stick with the stock rocker ratio (1.7). Going to a higher ratio is a way to get more lift from a stock cam. The main issue is that the added ratio makes the valve train a bit more unstable which is bad. If you are already dropping in a cam, just get it cut to the lift that you want from the get go.

Get us the lift numbers if you can.

Thanks for the input. I'll chime back with what I end up getting. Going to hop on LS1tech and ask patG.

Waiting to hear back from patG, still waiting for lift numbers for that 115lsa cam.
