So the cam that came with the Maggie 112 that I bought from a member is a good NA cam but not a good cam for an FI car. So I am looking at either the LS9 or the GT2-3 cam. I'm leaning torwards the GT2-3 because I want a some what lopey sound. My question is will I need to do anything to my heads or will I be fine with the 112 and GT2-3?

So I am selling the cam I have if anyone is interested.


Thanks
Jay

Specs on the cam and how much? Pics?

ichpen

Here it is:
LS1-GT2-3 207 / 220 .571" / .578" 1.7 ratio 118.5

LS9:
211/230 .558/.552 122.5 LSA

Looks fairly mild still, you won't get much lopey lopey.

gt9 or gt11 cams are a bit more aggressive?

I dont want anything to lopey but something that lets you know the cam was changed. It seems like most people go with either the gt2 or ls9 with the mag 112

The cam I have now is 224/238. It says Grind#: Maggie 112. But according to a few shops its really for a NA car. Not sure on a price yet but I do know I wont take nothing under $300.00 for it.

Well I'm running an ls9 cam and not much lope as I had before, almost sounds stock (ish) except of all the other craziness I did to it. On the positive side it doesn't stall in underground parking lots as much.

The LPE cam is your better bet, if you want something more aggressive get the gt11 cam but it's higher lift so you'll need to beef up your top end a bit.

Thank you for the help!

Should I do a new timing chain? Also I dont need to mess with the heads right except change pushrods, springs etc right?

ichpen

You should do timing chain, melling pump, springs, rods, rockers. I don't know what heads you're running but you should be fine with that cam. Check with LPE though, they should give you a definitive.

Do your homework and make sure you get the appropriate springs that match your cam and do not overpower your rockers. There's a bit of research here.

LPE GT2-3 207*/220* .571"/.578" 118.5 LSA

The cam you already have in your LS6 right now...02'+ LS6 cam 204*/218* .551"/.551" 117 LSA.

Not to be a hater, but I'll bet money that you are not going to feel any difference in 2* duration, 0.20" lift, and 1.5* LSA from what you currently have. Go with the LS9 (or even LS7 cam, only difference between the two is the LS7 cam has 2* less LSA at 120*). Or, get a dedicated blower cam if you can stand some lope.

This is the cam that came with the maggie. It seems rather aggressive for a blower.

DMM

113* LSA with 4* advance ground in and 14* split to the exhaust...gonna lope pretty hard but will really help to add torque where the Maggie does its magic. Going on memory, these spec's aren't too far off from the SNL Blower cam (you can search results of that), which works really well. If you have a really good tuner lined up, I say go for it if you are already looking for some lope.

lope pretty hard to almost stall? Stock heads are ok? Sorry I dont know much about cams I'm still learning.

DMM

No, not nearly what you are thinking. There will be no doubt that you are cammed just by listening to it though. You will also have the "sewing machine" noise at idle. I believe there are a few YouTube clips of the SNL Blower cam so you can generally make your own decision. You also have to consider what drivability you need to maintain, emissions requirements, etc. as this will not be an emissions viable choice.

Stock 243 heads are fine, but you will need .650" lift springs (min) and the correct length hardened pushrods. If you are doing your own install (its really not too hard even for a novice) spend the $10 on a pushrod tool and verify your exact length.

Lots of info out there, you have to decide what your requirements are (drivability, emissions, etc) and make your own choice. The idle clips really help when trying to decide though.

I have the gt2/3 cam in my twin turbo C5 vette. Idles like stock. No lope at all.

The cam you have only has 5 degrees of overlap which isnt bad at all. Its not optimum but i dont think your giving up much at all putting that cam in. Id be more worried about that maggie running out of air up top with a cam that size though. I bet itll drop like a rock at 6k rpms.

Have you checked out any of England Green's cams? They seem to specialize in PD blowers. They also have some pretty good sounding (lopey) cams that seem to hit very respectable power numbers as well.

Yeah thats another thing I was wondering about up top how this cam would do. I think I am gonna install the maggie first and think about which cam to do instead of doing both at the same time. Gimme more time to think about it

i believe im correct, but while you are looking to confirm on these camshafts, it may be note worthy that the ls9 camshaft specs are on a 1.7 rocker ratio, and the ls7 is rated at a 1.8 rocker ratio. cost effective and you not wanting a choppy camshaft, LS9 all day. they are 159 i think, it runs the factory ratio. im sure it will still make great power, even though it was designed for the larger bore 4.065 and has rectangle port heads that can really flow.

OP Bear in mind with the LS9 you aren't going to be out the door for a bill. With our LS6's we require a bunch of crap to run the LS9 cam because our cam sensor is at the rear of our engines.

From this link: http://www.lingenfelter.com/LPEforum...LS2-LS6-or-LS1

"The LS9 camshaft is a 3 bolt design and will use the Lingenfelter 3 bolt cam conversion kit if you are installing it in a single bolt application like the 2007 – 2010 LS2 or LS3. If you are installing it in an earlier LS1 or LS6 engine with the cam sensor at the back of the engine you will need a 2005 LS2 front cover, 2005 1x cam sprocket, camshaft extension harness, 2005 LS2 chain dampner."

It isn't that you couldn't make it work but for me all the additional crap made it a no go. I'd rather get a more aggressive cam anyhow if I'm going to toss the fairly boost friendly LS6 cam.
