Default Forged 347 Cam Advice. Please Help

What cam would you guys suggest in a forged 347 with flat top Mahle pistons and rods, stock crank, ls6 intake, pulleys, longtubes, and just really full bolt ons. I am either going with ls6 stage 2 heads or maybe TEA stage 2 heads. Neither have been milled. What cam would make the most power and good rpm and torque range?

It should be included in the price of the short block.

That cam is ver similar to the X3 cam.. It will make descent power, but I think a little bigger cam would not hurt.

Most machine shops charge around 150.00 to 250.00 for a balance job.

You also need to keep into consideration about clearance issues as well, so bigger might not work though with flat pistons....

I dont think clearance issues will be too big of a problem. They have 4cc valve reliefs. Keep the cams coming

What do you plan on doing with the car??? Is it a DD or a track only car or a weekend car??

What gears in the rear?? Tranny? Are you going to spray it?? All Motor??

All of these are questions that need to be answered before any valid cam can be suggested. Other than that they are just shots in the dark.

Mods are:
M6
3.73s
ls6 intake
42 lb injectors
pulleys
longtubes
ported tb and maf
lid
loudmouth exhaust
forged piston and rods
stock crank
etc

This is a weekend car only. I am wanting to spray it occasionally. Maybe a 150-200 shot. This probably going to be with cnc ported ls6 heads.

It really depends on what you want. What was your old set up, did you have a cam in it, if so what were the specs and how did you like it? So guys like smaller cams, some like bigger cams, it just depends on what you are using it for and what you want out of it. As far as off of the shelf big cams, MS4, Vindicator, G5X4 etc. have made good numbers and good times. I personally went with a Vindicator.

The next step smaller, G5X3, Torquer, F13, F14, etc. have all been proven performers. This might be the range that you want to consider if you are wanting a "good rpm and torque range". The G5X3 is a great cam.
