Would I better of getting a maggie or.......

[Naf]

Well if you have a 6.0 bottom end you could get the L98 heads and intake and score about 500hp at the flywheel...Not to mention a nice smooth cam all for about less then 3,000$..I was going to get the whole kit from LPE but the intake manifold was discontinued and well i didnt feel like lookin for another on the net...Hard enough for me to score parts as it is...

Still havent hit the dyno for a proper tune or numbers yet...Way too many things going on here plus my Tahoe is havin issues with the new engine i installed...
Stock LM7 with LS6 cam and SSR Intake manifold...

Big cubes, very mild cam, and big grin. Stock-like driveability and mileage.

Done right, there's no substitute for cubic inches.

Shipping weight is 100lbs.

Some pieces of the kit replace stock pieces, so it's going to net to a weight gain of full kit - stock parts + 2 gallons(16 lbs) of coolant/water.

EDIT: Minus the weight of the crankshaft drill bit, of course.

Maggie cars appear to sit lower in the front.
The weight must be enough to affect front ride height.
Perhaps a GC kit is a good idea for Maggie owners.

Dammit, all the good answers have been given.
Try to get to a V meet and drive both, both will impress.

Another thought if you can do the work yourself is H/C with rotating assembly and a NOS kit-this will get you above 500RWHP.
Or pull the motor, go Stoker with 12+:1 and sell you LSx.
There are lots of options, which is why I think the Maggie is the most chosen path, as it is easy, proven and reversible.

P.S., how long has the cast iron Maggie been in production,,,

[jerrycecco]

ok, I'll jump in the pool now....
I have a 2004 CTS-V.......I did the supercharger, tuning, pulley, suspension (all the work) to a 1996 Cobra, when I live in Oakland.
Today, I live in Dallas where the temps get into the 90+ ALOT, I'm looking at cam and headers.
I beleive the LS6 V's put down about 330RWhp (correct me if I'm wrong)
After talking with QMS in Lewisville, hitting 410+ rwhp is acheivable.
So I'm looking at getting the Kooks 1 3/4 headers, cam*, ported/polished throttle body/intake & tune.
*Only question is cam size. Patrick @ QMS talked about two cams:
street cam @ 224/232 or step up cam @ 228/236.
From the dyno sheet attached I like the step up cam, but like to see how it idles and how the cars drives at low, parking lot speeds.

Q to CTS-V owners with cams: What cams your running? what HP did you achieve? quality of ride post cam installation?

First of all, this is probably not pertinent to 5.7 and 6.0 guys since I'm running a complete LS7.

I 'm running a 218*/232* on 118* centers. It's basically a similar grind to the LPE GT11, but has lobes compatible with the 1.8 rockers in the big motor.

Since the profile is only slightly more aggressive than the stock LS7 cam (211*/230* on a 120* center) the cubic inches swallow it up and it idles better than the stock LS6.

It makes 350 lbs/ft at 1500 rpm, crosses the 400 lbs/ft line at 2500 rpm, stays above 430 lbs/ft until 5800, peaking at 446.81 lbs/ft at 5200 or so. It drops back below 400 lbs/ft at 6350, and ended the run at 380 lbs/ft at 6600.

The hp peaks at 469.02 at 6000 rpm.

I have some losses in the intake tract, as the stock tube collapses noticeably under heavy throttle and my throttle body was rather crudely finished inside (it's now ported). I'm going to fabricate a new tube as soon as I decide whether I'm going to A larger MAF (100 mm), which will govern the tube size.

I may also clean up the manifold a bit, as there are some severe mismatches in the port ends of the runners.

These changes will probably be worth 25 hp or so, with no changes in driveability and at not much cost (unless I go to the 100 mm MAF).

I can always upgrade to the LPE GT19, for some real short-staining power. I just don't know if the driveability and valve spring vigilance is worth it in a car that's not raced (.678 lift is not the best for valve spring life, even with the Ferreas).

Just dyno tuned my car with mods below, pretty stock except maggie. Drove lunarx's mallet 427 and ran around with him. They are very different feels. My car pull's the 500RWHP mallet off the line for about half a gear, but then he catches me and as I shift I stop losing as much ground (gears are different also). Mine idles like a stocker, mallet rumbles like a race car. Depends on what you like.

[heavymetals]

Mallet is a race car.

[CTSV_Rob]

The answer to the question is both.

Seriously though, I was geared up to go head/cam until I got the deal from Rick. If you have an LS6/LS2 there is a boat load of parts out there for it and I found some articles where they were putting down some serious horse power with a Cam Swap and some Impressive gains in torque if you change the heads and Cam.

Maggie for me for now.

So you got 458 RWHP with just the Maggie and a tune??? Which pulley do you have, the 2.8 or 2.6??

I 've got headers so I wonder what kinds of gains I should expect, hmmmm.

Not yet.

Perhaps after, my new Cam and Heads go on.

[CTSV_Rob]

...and the 90mm intake, polished throttle body,..... It never ends Lunarx.

[heavymetals]

I haven't seen the non race car version of the C5R block. LOL

I don't know what is stopping you from pulling the pin and going full on.

You should be well on your way to +600hp.
