Who has this setup ws6 6m, lt ory with gmmg cat back exhaust with slp lid and smooth bellow, 243 milled heads and lpe gt2-3 cam? I want to see about how much rwhp can i get with this setup

SoFla01SSLookinstok

I had the GT2-3 for a tad. The heads I have maybe a little better & a FAST 92 manifold. It put down right about 420/420.

i forgot to mention i have the ls6 intake, do you think i could hit 400rwhp?

SoFla01SSLookinstok

I would think you should be in the area of 400. Can't really say if you will, with all the variables, but I think it could.

How did you like the lpe gt2-3 cam? Also what kind of exhaust do on yours

SoFla01SSLookinstok

I liked it because it's a true sleeper cam. The exhaust was 1 3/4 long tubes, ORY, to magnaflow cat back.

SarGntoperez

Thats a nice setup but magnaflow muffler is lil quiet huh, im going with a 1 7/8 speed engineering lt with ory, i already have the gmmg catback on it, cant wait to hear

SoFla01SSLookinstok

Yea the magnaflow is a bit quiet. I liked the tone/sound at WOT. Yours should sound good.

With stock 243's, LS6 and a GT2-3 cam I think you will around 390whp. Port the heads and 410 should be within reach.

wat kind of springs and pushrods u used for thst set up with the gt2-3 cam

SarGntoperez

Who has used this lpe gt2-3 cam on ls1 and what kind of setup and results did you guys get?

That cam is designed to work with factory push-rods and either the yellow LS6 or the Blue LS3 valve springs. It would most likely be a SMIDGE better to put the PSI MAXLIFE 1511 springs in and a quality .080" 5/16" push rod in as well

I just bought some texas speed 7.400 chromoly pushrods, will those work? I was planning to get the PAC 1218 behive springs what you think about those? They good for .600 lift

The PAC 1218 springs have an excellent reputation, but the beauty of the LPE GT2-3 is that its lift profile will accommodate the softer (and thus theoretically longer lasting) GM yellow LS6 and blue LS3 springs as mentioned above.

The general idea is not to run any more seat pressure than you really need.

hey buddy what was your mods when you were using the gt2-3 cam?

That sounds like 380 to 385 wheel hp in an M6 f-body to me on a typical but correctly calibrated DynoJet.

I would make a few changes to the list if shooting for 400+ with the GT2-3 cam.

• 25% under drive pulley with overdrive for the alternator
• 90mm FTP lid & 85mm MAF
• LPE /TPiS 90mm snout mod for the LS6 intake
• 92mm throttle body
• Cut out for I-pipe / midpipe pile before catback - ideally electric
• Get the 243 heads ported with a quality valve job. TEA, AI, Frankenstein, Land Speed, LPE all all excellent choices. Explain your goal and it's a GT2-3 cam build. I would favor the springs A. R. mentioned.
