Engine trade- upsizing

Guys, I am considering making a change from the 4.0 in my 98" wrangler. I have discovered a shop or two that is making 4.6/4.7 Stroker motors out of these stock 4.0's. They are supposed to produce about 75 more hp than the stock set up. Does anyone have one of these? My other option is going with a 350 create motor. I know if I swap my engine for the beefed up Stroker, everything with the exception of the injectors will be good to go. Does anyone know how much of a headache converting to a Chevrolet 350 will be? Any idea of the costs? I know the Stroker 258 is running about $2400. Can anyone help guide me on this decision? Thanks

32 dollars per horsepower seems really expensive to me. You will invest more than 2400 to install a Chevy V8 in your jeep.

i did a stroker on my 4.0 i had the crank and rods from an older 258 but you can pick them up on e-bay pretty cheap the machining for the new heavier springs did a valve job on the heads and redid the valves, bored it .60 for new pistons machine work=1100 master rebuild,mustang injectors,adjustable fuel reg,map sensor,water pump, about another $1000 and according to what ive read im putting out 365 ft/lbs torque and 285 horses and i think it was better than a 350 i get 21 miles to gallon i think it ws well worth it and i didn't have to mess with trans and transfer new radiator for cooling motor mounts hole in tub for shifting and exhaust

Thanks for the input Bowhunter. Do you have an auto or manual? I think I will go with the stroker, it sounds like a much easier swap. I would like to know specifically what you noticed the most from the upgrade. I was told that these engines are built to distribute most of their power in the low end, so I know that would be great for off road. How much difference have you noticed on road?
