Here is the engine in the Duster that I'm building for a series in Car Craft. This engine makes 700 hp on the dyno but it should run down the road just fine. The idle might be a little aggressive since I don't have variable cam timing but it won't be bad. It will idle better than 90% of the hot rods out there that have a carb and it will get better fuel economy. Very, very few guys know how to tune an engine better than the feedback loop on an EFI computer.
