I researched and gathered the parts to do the same swap but decided to stick with the 4 cylinder as well. If you do this I have one of the rare 4 barrel intake manifolds and the Mopar performance distributor to allow you to avoid all the ECU and wiring hassles. I will sell these for what I paid for them. I also have a pair headers (ceramic coated) for this motor and a pair of brand new rebuilt magnum heads.
