Hey guy's i'm in the process of rebuilding/ minor stroker motor on my 96' 4.0 Grand Cherokee ZJ and really need to input/ advice on my build. I was originally going to build a 4.7 stroker but i've decided against because I am custom swapping in an AX-15 5spd trans. when I drop the motor in rebuilt and I know for sure that the trans. WILL NOT be able to handle the HP of a 4.7...i'd be lucky to keep it intact til 3rd gear before blowing through it so I decided to do:
-complete engine rebuild w/ hi flow oil pump
-bore it over .30
-Comp cam https://www.summitracing.com/parts/cca- ... /make/jeep
-Comp valvetrain
-Comp timing chain/gears
-Port/match my head (pulled a 93' XJ head), intake manifold and Gibson header's
-Performance Distributor's Firepower ignition (screamin' demon coil pack allows you to gap spark plugs to .065)
-Roller Rocker's..can't decide whether to get Harland Sharp 1.6 adjustable rockers or Yella Terra's ( I can get the Yella Terra's cheap)
-SCT tune
-Custom full 2.5" exhaust back (Magna. Hi flow cat, Flowmaster 44 muffler)

I already have the Comp Cam kit( https://www.summitracing.com/parts/cca- ... /make/jeep ) however, i'm not sure if the cam is too lopey for a non- comp. head or modified head...anyone have any advice or two cents?
Also if anyone has any suggestion's or critique on the build, I am all ears for suggestions!

Thanks guys!
