Need cam ideas for my 318 Duster

You are going to have a 3 digit problem getting a 12.4 quarter time, 'easy mannered', daily driver.
Those 3 digits are 3-1-8. I can suggest cams etc like the others have posted, but I think you should re-think your goals with that small engine.
And don't waste your time with the DCR calculator, like others do. The quoted 'seat' timing varies between manufacturers because they use different tappet lifts, anywhere between 0.004" & 0.008". So that is one variable that affects the final number....that is NOT taken into account. The real problem with the DCR calc is that it uses the IVC number as a guide to how much air is drawn into the cyl. That takes no account of how well the intake port flows & in your case with E heads, you would expect more air to flow into the cyl compared to a stock head.....but both would compute the same number for the DCR!!!
