Wonder how they sound compared to stock. ????
And valvetrain required or not?

As far as the valvetrain, the cams are designed to be used with the factory valve train and springs, although we strongly recommend to upgrade the springs since you are already there.

A basic spring upgrade would run you about $250, FYI

BUT there is not doubt there is a really solid midrange boost and they work really well with my Greddy kit.
(FYI: in case someone mistakes my joking... I think the GTM cams are very good. I actually sold my JWT C2 cams for these... The fact that your average person can't tell what my car is capable of until I romp on the gas.... VERY VERY impressive...)

Gee, thanks Sam.... I have not even had a chance to start pushing the stroker kit I have and you are already releasing bigger/better versions .... 
SLOW DOWN bro.... Take a vacation or something... Let some of use catch up with all the new stuff you have put out before overwhelming us with new product...
I mean, do we REALLY want to go through another build for me this year.....
Just so I can stay on the bleeding edge... HAHAHA
Good luck with the new cams... maybe that is something I can upgrade in the winter if I feel I don't have a large enough power band . LOL

PS. I could use a new 3.3 final drive, that would work with an ATS diff before mid July though..... :HINT:HINT:

I assume this was with the Stage 1 Turbo Cams. How about the other 2 that GTM sell as seen below.
Quick question though why does the Stage 2/3 cams duration swap around compared to Stage 1 ie: Stage 1 has a higher duration on EX and Stage 2/3 have a higher duration on IN? Also can anyone explain "generally" which of the cams you would use for what purpose or goals.
Stage1:
Intake: 256 deg (stock 238)
Exhaust: 264 deg (stock 240)
Lift: 0.423” (intake and exhaust)
Overlap: 18 deg (at 0.045” lift) – less than stock
Stage 2:
272 degrees @ .012”
232 degrees @.050”
11.00mm Valve lift intake and exhaust
Stage 3:
288 degrees @ .012”
245 degrees @ .050”
11.50mm Valve lift intake and exhaust

I currently run the stage 1 cams. My cams, showed good midrange power and still allowed power to be held through redline. As you move to the stage 2 and then to the stage 3, you are most likely pushing that power higher up in the revs; and making more of it

It isnt a stock Vortech....then stock Vortech with his cams . The first dyno...the car had problems [ somewhere ] it only made 300whp on a dynojet . The second [ with cams ] the problem no longer is there . Easily seen by every one . But only you and I asked why .

have any others dyno'd this setup on a stock vortech setup vs. stock vortech setup + cams?
the one here has a built block and so it adds a few other elements to the analysis.
any extra info would be great. thank you.
