Im strongly thinking about getting one of the Aluminum block Explorer engines from Karkraft. Im having a shop do all the swap and i have my original motor to swap everything over. Im wondering tho that the explorer motor is not rated at 260HP i believe its around 220? Why is this?
I beleive all the 4.6 motors in the Explorers are PI, but even that being so the power difference would come from different cams, different intake, different exhaust, and tuning differences.
