If you think your motor is ready for a rebuild, you should plan on new pistons, rings, and bearings regardless of weather or not you have to bore it out.

I do believe that a stock bore that is properly milled to get quench into spec will have low enough compression to run mid grade at least. Jeepstrokers.com has a compression ratio calculator you can use to figure this out.

I was under the impression that you thought you could build a stroker for $300 on top of the cost of just rebuilding the 4.0

I am going to use a 258 crank and rods and get 6 over pistons and bore my current motor. I have heard with a mild stroker build you can compensate the computer programming aspect of it with mustange injectors and a adjustable fuel pressure regulator.

Its all french to me.

what machine shop are you using
I use a machine shop out in Holly that is called SGB Enterprises. The guy that owns it and does all the machine work there is a great guy. He does all the machine work for all of our shops. He has built several jeep stroker motors. One of them was in a Cherokee of I guy that I work with. It seemed to run well and held together through some abuse!! If you want his number shoot me a PM.

Regardless if the $300 is the whole budget, or on top of the rebuild budget, I'd be tearing the thing apart first to see what I had to work with.
Spending $300 on parts to stroke it won't do a bit of good if you tear it down, realize you need to bore it (requiring pistons/etc.), then can't afford to finish it.
I still don't see the sense in worrying about 87 octane so much. You realize if you put 500 gallons of gas a year in it, if gas is $3.30 for 87 / $3.50 for 93, you'd only spend an extra $100 over the course of 500 gallons.

And that's likely 5000-7500 miles a year, that's more than occasional use.

Titan engines offers a complete stoker engine kit (including a machined block and rebuilt head) with all new parts for $2000. All you have to do is assemble it.

What would you suggest I do to the head?

Spend that $300 on a cam and headwork. I run a comp cams extreme 4x4 in my I6 along with a good valve job and love it.

Better yet, cam, get head rebuilt and then gasket match all the intake/ exhaust ports yourself with a $35 grinder set.
Suggest a cam over 258 crank and rods?

I have plans to stroke my 4.0L in the future as well, refresh it and get a little more out of it. I hope thread gets back on track....
Thank you!

I know I need new bearings, oil pump, water pump, rings, gaskets etc. I didn't think id need pistons for sure

For $300 more id be ok with 20hp



I may go to a 5.3 eventually but while rebuilding it why not spend $300 or so more to get a little more pep. It will be cheap and simple I'm not as cheap as you

Good to know. Thanks



Will my quench and CR be fine with just putting in a 258 crank and rods I don't want to do pistons unless I have to. If I do this will I need special head gaskets?

At first I thought I would individually respond to some of the things you said. But instead I think this will cover it.


You need help, like skooterbuilt levels of help. Stop posting.

Why would you spend 3-400 on a 258 crank and rods when I see whole motors go for 200 or less all the time

Used that need to be pulled, then scrap rest, hope they are in good shape, send out to grind..... vs. In a box new? Is this the price difference?
