search my name on this forum. You will find all the info you need for a rebuild/stroker.
The stroker can be done for around 400 dollars, WITH NO BORE. If you bore it, you will just have to add in the machine shop charges.
Promar performance is your best bet for picking up the rebuild kit. Modularfords.com forums is your best bet for picking up some 24# injectors. Bought 4 sets from them, most expensive I paid was 80 shipped with only 2400 miles on them and flow tested. Local jeep store for the .043 mopar performance head gasket (28 bucks). Radio shack to build your adjustable MAP sensor ( 10 bucks). Initial tune on the map, good place to start.....5.15 on a 4.6L and go from there till all knock is gone and plugs look good. Also, change your plugs to atleast, ATLEAST one stage colder.
I run a 4.7L, two stage colder plugs, map at 5.12V, 89 octane(personal pref. could run 87 but choose not to) and my jeep flat out hauls. I have stock gears with 31's and I have no problems goin 75 down the highway in 5th, or pulling a ranger with 10" lift thru mud holes cuz his tranny blew. Very worth while mod, and if I get more time, I will finish my write up of my stroker motor.
