Use nice shiny cam with some bumpy bits on it, and also some smooth bits in between, and a hole in one end.
If you want any useful advise you'll need to detail your engine and driveline combination.....

If using GT40P heads, choose a cam that provides lots of duration to really fill the cylinders and install some roller rockers to get as much lift as you can out of the 40P heads.

That doesn't really suit a DD wagon with an auto does it? Find the biggest cam you can & bang it in the hole... Crane 2020 or similar.

Look for a lobe separation around 114°, it will help keep the ecu happy. Are you running the standard converter? If yes then duration at 050 about 220°, if you're running a 2500 stall converter try around 224-6° at 050. Roller rockers as Vic says and make sure the valve train is upgraded from the rubbish factory retainers & springs. Check p/v clearance, usually OK if under 500 thou lift. With stock GT40P heads there isn't much point going above 500 thou anyway. Intake, TB & MAF are too small for a 347 really, but I'd go 70mm TB and 80mm MAF on stock-ish GT40P heads and intake. 30lb injectors. And a piggy back chip on your ecu to run the bigger injectors & MAF. Check fuel pump keeps up under load.

You have a 347 not a 302, so I'd go bigger along the lines I suggested. That Lunati is very similar to a stock 220kW AU3 Tickford XR8 cam (so it's quite tiny), but has 50 thou more lift and less lobe separation. Look for 218-220 at 050 INTAKE and 114 lobe separation. Keep lift around 500 thou. Run standard rockers to start with. If you're happy, replace with 1.6 roller rockers. If you want a bit more power, go to 1.7 roller rockers. Select springs etc to cope with advertised cam lift x 1.09 minimum.

But check out some other manufacturers as well. Also, talk with the tech-line and explain your parts combination and the type of results you want and see what they recomend
