(I just built a 4.0 based inline six stroker motor, (now it’s a 4.7) for my CJ-7. I spent about 20 hours working the head on that motor, it has LS1 valves, beehive springs, and more cam, I’m hoping to make about 250-275 HP with about 325-350 LB/FT of torque, right off idle. Power comparable to a stock SBC. Either way it should be better than the 110 HP the 258 (4.2) inline six was rated at when my Jeep was new.)
I built a 4.7 for a Wrangler I had, 258 crank, 4.0 block. Ended up using the Edelbrock head, Comp Cams has some good profiles for that set up. Your HP goals should be easy to get. With the ported e head mine made 300HP. With 4.33 gears it was fun.
