Hi, I have following project in my mind. I do have Jeep Cheokee XJ -92 with 4.L HO engine (243 MBI). IT has +160 K miles behind and I have started gathering parts for my spare = Stroker engine. Now I hope that somebody out there do have some experience or other way acquired know-how above mentioned topic. I do also have an 258 6-inline engine from Cherokee -80 where I'm goin to get my stroker cranksaft. Then I have an 4.0L (243 TBI) from Wrangler -87 where I'm goin to take the engine block (+studs).
So I try to fix together 3-engines and get one ~ 4.6L HO one.
I repeat a little:Engine block from Wrangler -87 (243), Cylinder Head + Injection System, electronics + Connecting rods + Pistons + Camsaft from Cherokee XJ -02 (243 HO) and Cranksaft from Cherokee -80 (258)
Now the questions: What prolems will I come across? I there difference with turbine plate/flyweel bolts at Crangsafts between 243/258 engines? What else? I will do total rebuilding with all available new repalcement parts and with local automotive machine shop help. Waiting You kind help.
Kindest regards,
