not to burst anyones bubble but the 5.7L hemi will outpull a 6.1L if anyone knows anything, if anything mopar was done to this engine they would have done a free breathing intake and exhaust, reflash the fuel map, eliminate the red lines, changed the shift pattern, and probably a lot more computer related stuff that i havent figured out yet for obvious reasons, im not a mopar worker. but since a stock srt-8 cherokee only runs a 13.8 at 102 quarter its not hard to believe that a 5.7 having the ability to rev higher and quicker with less mass could accelerate the lighter jeep to the same area or faster.
just my 2 cents, im not against ford or for chrysler, i just love building things and engines are the top thing to contemplate in my book
im actually givin the go ahead on my friends ram when he gets a different car, im going to find someone to sleeve it without boring it, drop the rotating mass, higher compression ratio (im thinking around 12.5/13:1 on E85) advance the fuel timing, custom build ITB's and free flow the intake and exhaust on it. with any luck were looking just shy of 500hp NA on what would be roughly a 4.5-5.0L v8
). When I test drove my Explorer Sport, I loved it. It pulls off the line and has great power too.
