I'm lookin to put a new engine in my explorer, but I want something with more power. Would a hemi fit? (even if some fabrication has to be done) Any suggestions as to an engine that gets more than 9MPG and has oodles of power and acceleration? I'm wondering if a v8 would fit in place of my v6 currently installed. If not then any v6's with decent gas milage (>18+ mpg) and power will do. My engines got 381k on it and its probably getting ready to go, it's got a new transmission (which happened to die 10km after the warranty [375010km]). The body and chassis are in near perfect condition, so I dont want to get rid of this if I dont have to.
Thx for all future input!
