Jeep Strokers

ok so in the future want to stroke a 4.0 what do i really have to do. my thought was 4.2 crank 4.2 rods 30 over pistons if it need to be bored. 4.0 factory cam would like to use factory pistoms as well even if .030 over i just have all the parts just dont want to put a ton of $$$$$$ into it. daly driver weekend camper to pull. lots of kids$$$$

Sounds like either my traditional "poor man's" stroker recipe or the modified poor man's is the one for you. Which parts do you already have?

i have a compleat 4.2 1981 j10 running and a doner 4.0 1998 4.0 109000 ?? on a pallet my 1996 4.0 daily driver 200000 miles what i want to accomplish is to tow a small camper 21ft on the weekends and daily driver not a rock crowler of mudder

i was looking at all the work that people do 0 decking piston dishing . crank grinding cam work can i just have all the parts checked out and put it together can i use factory pistons no dishing . the thing i might do is port and polish by trade im a tig welder aviation have done some grinding. cheap but want to know if its a good build for what i want to do? thanks for chating with me on this. the shops around me have not even heard of stroking a 4.0

Im doing somethin pretty similar as your describing
.030 bored
new pistons
4.2 crank and rods
stock cam

Its actually a pretty simple stroker set up when you keep the factory cam.

Then you can do a traditional poor man's stroker like mine using the 258 crank, 258 rods, and Z677AP pistons.
