427 LS3 cam?
Sup guys
I searched around for my answer but nothing was very specific to my needs. I appreciate your help ahead of time. I'm installing a 427 LS3 in my 06 M6 GTO in a few months. Im trying to find what cam specs are being used and what kind of power is being made to the wheels. Dyno graphs as well as your 427 setup is appreciated! Build will be as follows: TEA LS3 heads, LS3 intake (untouched), 90mm TB 4.070" flat tops with 11.2:1 compression 6.125 compstar rods 4.125" compstar crank 1.75" headers, 3" catless mids, will be a 3" exhaust Im also up in the air about the FAST 102 or NW 102 setup, seems to give little power for practically $1400. Anybody dyno stock setup first before moving over to a 102/102 setup? Thanks for all your help Camaro brothers. |

Very few of us have 427's. You might want to go to a ZO6 corvette forum.

Why are you going with 1.75" headers instead of 2.0"? I would think that would be a bottle neck.

Comparing a LS7 427 and an LS3 427 is apples and oranges when it comes to cams. Beyond that our cars are similar in weight as well and would be considered more comparable.
As far as the headers, its extra money that I'm just not currently investing at the moment. There are no 2.0" primary headers that are offered for the GTO in an off-the-shelf form. I'll search for darth emma, thanks guys! |

There are probably less then 20- 427's on this site...
The other item is that most all of them are using one form of Forced induction or another... Head and intake selection need to be considered as well.. There are a number of vendors on here that will help you with your selection though... Lingenfelter, Texas Speed, etc...

I was hoping to hear some experiences from owners rather than vendors. Calling is always a sales pitch and I wanted to avoid it, but I'll start tomorrow.
Thanks for the replies guys |

Have Pat G spec you out a cam. The one specced for my ls3 429 is in the 25x/26x range, .65x lift on a 110ls
Course I've got a ridiculous intake and 13.45:1 compression, too :p

Brian, You do have a few restrictions to this engine that should be taken care of... The TB and headers are too small for a big power maker. Swapping to the 102 is a great idea. A set of American Racing headers 1-7/8" tubes as a minimum too. Nick can set you up with the right ones. BTW - picking cam specs over the 'net is akin to Russian Roulette. The chances of getting the right one are slim. Ed

Give us a call I think we can help you spec something that will work really well with your application. We've built 670+ flywheel horsepower LS3 strokers so I think we'll have some data to help with your selection!

Well the 427 isn't a new engine for us, if you need something custom ground I most certainly do not have an issue doing so.
