340 - This thing should run better

put the timing up about 18.it will run better right there....

I wouldn't just say that without also asking about the total timing - which is a much more important number. Total timing should be close to 36 BTC with all advance in. Makes sure it is not detonating or you will kill the engine quickly.

Are you sure about the cam initial setting? I understand that the recommended initial setting for a Mopar Performance purple cam should be 3-4 degrees less than Ma Mopar says (though I'll leave this recommendation to more experienced FABO members). You can't guess on this setting, it must be measured with a degree wheel or tape! Having this number off will certainly kill power development.

Yes, in my opinion, your car specs should be a screamer! If its not, then something is far off. Good luck in tracking down the problem!
