440's are great.. but if ur car runs too rich at idle or any or area regularly the motor isnt going to last for shit. why? because of over fueling... fuel is a shitty lubricant. matter of fact ew use kerosene to clean engine parts {well not anymore really, but u get the idea} all that extra fuel washes oil off the cylinder walls, and seaps past the rings. oil will take on a gassy smell and kinda of translucent color. bearing life will be greatly diminished, as will every other part of the engine.

but uhh yeah...you can tune most of that out with a clever fuel pressure curve using an adj regulator and a fmu that has like a 1to1 or similar ratio, and an afc.... not the best route. but it works for the wallet.
