First off let me say I've searched--a lot--and I can't find what I'm looking for...

Supporting mods: lid, fast 90 intake, nick williams throttle body, underdrive pulley, nasty modded stock rockers, 1 3/4" longtube headers, ORY, catback, rear gear matched to the cam, etc. This is on the stock bottom end and Naturally Aspirated.

In the future, I also plan on getting ported ls6 heads with larger valves, and milled some for more compression.

What I want to know is: Which cam will provide the quickest 1/4 mile E.T.'s being shifted AT or BY 6500 RPM? I don't want 7000 RPM screamers like the Trex, G5X4, etc. I could care less about dyno numbers also. I just want it to accelerate as quick as possible in a straight line with the 6500 RPM shift limit.

Needless to say, it's gonna have to make some pretty decent low and midrange torque. Also, my question refers to Off the Shelf cams, so please don't say go Custom. I'm considering going custom anyway, I just want opinions about OTS cams.

F11, F13, G5X2, G5X3? Or something smaller like the proven C1 Hammer Cam? Or something else?

Any advice is appreciated.

Thanks for the input.

I've sort of been leaning towards the G5X2 lately, but I'm welcoming everyone's opinions. Especially those who have more experience than myself.

My biggest concern with the G5X2 would be P to V clearance when used with Milled LS6 heads. I don't know exactly how far they could safely be millled, and to what compression without smacking pistons off of valves?

Also, I don't remember if the G5X2 likes to be shifted in the range I want, or higher? That would help make the decision. I do remember that Louis'(LGM's) cams put out good numbers, both at the track and the dyno.

I remember reading a lot of good stuff in the past on all these cams when I did searches, but now the search function seems to not give near as many results. Like it deleted the old archives or something?

Keep the advice coming guys!

Might want to think about the Dart 225 head.
The biggest advantage is it start out as a 62cc head with close to stock PTV, has double quench, and about the right size runner.

You'd probably select one cam for stock heads, and another for ported heads. REally it comes down to airflow, and RPM. You can use some of the bigger cams, you'll just end up witha narrower lobe sep. The only issue there is, can whoever tunes it, tune around a choppy idle...

You've listed a wide array of cams with a lot of different durations and specs.

I'd look around.

224/228 113+2
230/234 110+2

Thats just sort of a 2 minute swag at it.

What would be the intended RPM range be for, say, a G5X2 on a 112 LSA advanced 4*?

From what I've seen from that cam, I remember it performed well with and without done up heads. I wish the search function worked like it used to...

But I don't want to be close minded on one cam, I want as many suggestions as possible.

Thanks for the post.

I should probably make some phone calls to the Vendors of the cams I'm looking at, lol. But I'd still like more suggestions from all you fellow tech gurus.

novi5.0- I've had the g5x2 and now run the g5x3 cam.for me they both drive and idled the same,no problems at all. the x3 got me down the 1/4 mi faster,so i like that one more. my x3 cam on a 112 only peaked at 6,400(x2 did 6,400 as well) and i shift at 6,600(ish) both cams have been great to drive and fast in the 1/4mi,i'm now looking to move up to the x4 cam and hope it's better then my x3.

lol why dont you just call comp and get your cam instead of calling LG, its the same ****.

Hey Mike--Thanks for the reply.

Was there any difference in bottomend and midrange performance between the X2 and X3? How much quicker was the X3 than the X2? What are your supporting mods? Did you have sufficient P to V clearance with the X3 on the 112--No flycutting?

Also, I see you are in Michigan as well. Who did you have tune your car?

Actually - that's not true. Most people think they can duplicate a cam simply based on the advertised numbers, i.e., a cam spec'd at 234/236 .589/.589 112 made by LG, Futral, Comp Cam, LPE, Texas Speed, etc. will all perform the same.

NO. Not the case at all. Those numbers are for comparison purposes only. There is a great deal to cam design beyond those reference numbers, which is why LG and others keep their specs, based on extensive R&D, a "secret".

I would personally go with the LG G5X2 or G5X3, those are both awesome, powerful, record-setting cams that don't have to spun to 7K, or another cam that gains less attention but is one of my favorites: the MTI Y1. It is similar to the G5X cams at 234/240, .598"/.608", 113. I've seen very good results out of this cam, including very fast H/C autos that put down upwards of 440rwhp.

The F13 is good pick for this too.

NOVI5.0- i did'nt notice a thing different in low to mid power from the x2 to the x3. now,when i went x3 i also swaped out my old poretd ls1 heads for the AFR 205 heads,so that would change other things. i gained near 50hp on a stang dyno going to the x3 cam w/AFR's. but as i said to me the x2 and x3 sound and drive the same. kirk from vector motorsports tunes my car,and will tune it again in april. his # is (586)453-9030 if you are going a cam,go x3 it will not drive any diff,but make more power.
also...you cant just call comp and get the LG cams,they use a comp gring,but they are custom grinds to LG and that is why lou is hush hush on the specs.
ALS0 NOVI5.0-if your in mich,too we should meet this spring and do some racing or something.

Thanks for the replies guys.

I'm guessing if I run either the X2 or the X3 I couldn't mill the heads any for bumped compression, without flycutting? If I could, how much could I mill and still have safe piston to valve clearance?

If it needed to be flycut, how hard is it to notch the pistons with the block in the car with one of those special tools?

x3 makes great power. with full exhaust and intake I trapped 116.7 in the 1/4, and thats on stock ls1 heads/ls1intake.
