Once the air/fuel mixture has been ignited, the piston is forced down on the power stroke. Factory aluminum intake non EGR.
Any I have seen pinged under load and power seemed to be down.
This can result in several symptoms that vary in severity and can affect everything from drivability to fuel economy. You'll need a timing light. I never seen anyone have any luck advancing a small or smallish cam beyond what is ground into them. Your ignition timing, on the other hand, can be throw off by any number of little things.
We wanted to actually put cam advance theory to the test, so we enlisted Alex Dunlap and his Dart to help us out.
Advancing the cam 4-6 degrees gave back some bottom end,(not a lot) but then I had to retard ignition timing to avoid pinging, retarding the cam 4-6 degrees gave a better top end (4000 to 7000), with no ignition retard required .
If the cam in the motor is the same cam timing as is this you could, advance it by a full 8 deg to improve the low end power.

Newer engines adjust the timing themselves, so as long as your sensors are all functioning as they should, you won't have to do any tinkering with timing. Sounds to me like your base timing is a bit too advanced.
In these engines, called "interference" type engines, even a slight slip in cam timing can be catastrophic and result in a complete engine overhaul -- thousand of dollars. So for longevity because of the pinging I would see better advantage running straight up? This causes the fuel and air mixture to ignite and push back against a piston as it is still trying to compress the fuel and air mixture. I'm not for sure which carb I'll be running.

This pulley has a notch or mark on it. by MPac » Wed Apr 25, 2012 8:38 pm, Post To advance or retard a camshaft is to change the alignment between the camshaft and the crankshaft.
This creates heat and volatility in the mixture. Also should the timing be adjusted at all with a cam that's been advanced? This changes the Timing of the valve opening and closing events, in relation to the position of the piston in the cylinder. google_ad_slot = "1939599277"; Incorrect timing will cause the fuel-and-air mixture to ignite at the wrong time within the cylinders. by PackardV8 » Thu Apr 26, 2012 12:38 pm, Post /* RT66-Link120x90 */ On most crank pulleys, there is another mark.
