I know that the 5.7 in my 2007 Ram 1500 won't last forever. Because of that, I'm thinking of getting a spare engine and going through it so when the time comes, I can just swap engines and have minimal down time.
I've read that the heads on the 5.7s flow well enough to support the cubic inches.....Unlike the old style LA, B and RB engines where the heads limit power, the 3G Hemi is not like that.
I want to maintain stock reliability but increase the power within the limits of the emission systems. I'm guessing that a slight cam increase coupled with better flowing exhaust may provide some additional punch while not adversely affecting the emissions and reliability.
Is there a published formula for this goal? Camshaft specs, header brand and part numbers, etc?
