Those with a NA 347 heads/cam/headers, LS6 intake & M6
I need to rebuild the motor again . I'm looking for daily driver cams that will easily give me 350rwtq from 3000RPM to as high in the RPM band as possible. No aftermarket intakes, hydraulic lifters, stock rockers, all stock accessories, stock T56, rear gearing near 3.73 if possible. Preferably a grind which isn't hard on the valvetrain. Graphs are appreciated.
I've got a Whisper lid, LS6 intake, PRC 5.3l 59cc heads, SCR ~11.2, ARH 1.75" headers w/ cats & a cutout. Current heads will be flowed "soon".
Thanks fellas...

Look for a cam with lift numbers in the 580's, they should help you make decent power and a good amount of torque without killing your valvetrain.
How about the g5x1 cam. Pretty stout baby cam from LGM, specs are available on their website.

I love my LPE GT-11... stay tuned, I'll have dyno numbers in a couple weeks. It might be a valvetrain killer... but LPE uses it in a lot of their street packages.

I did that with a TR220 and a set of PRC 5.3 stage 1.5 heads. See the link below. Good luck.

This might be difficult with an LS6 intake, keeping the same heads, and without an aggressive cam. I had 350tq at 3000, 400 at 4900, 380 at 6000, and 350 at 6500 with Patrick G's cam. That's up 20-40tq compared to the TR220 graph, albeit with their stage 2.5 5.3l heads.
I've read good things about the StreetSweeper cams, and Jeff @ Thunder recommended a 224/230 113 cam. But he said the cams could take 3-14 days depending upon load. Jeff also mentioned that Comp is blaming the lobe wear issues on using synthetic oils with insuficient antiwear additives, and they recommend using dyno Rotella 15w(hmm, 40 I think it was). No idea when the machine work will be done
Can y'all give me an idea of what your respective curves looked like with those cams and mods?
