New motor, Stroker vs. ???

Hi all,

My 2000 xj had a cracked head and low oil pressure, long story boring I've replaced 3/4 of the motor (head, main and rod bearings, oil pump, lifters, arms, rockers) still couldn't fix the low oil pressure problem. The last possible cause could be the cam bearings so now that I'm stuck pulling the motor why not upgrade the stock 4.0?

Since I'm a garage do-it-yourselfer I decided a swap to an LS1 or 5.2mag would be out of my range of abilities with the transmission and electronic adaptations needed. Decided the easiest improvement would be keeping the current 4.0 and get a stroker kit, machining the current block etc.

Any other options I should consider? I don't want to spend more than $2,000-$3,000

Thanks!

To stroke or not

I stroked mine for around $1300, didnt need a head though.
Bought a 60k motor and rebuilt it so i could drive my junk untill i had it ready to go in.
You could get a head and replace your cracked on and build a motor on the side. than swap over the new head.
Keep it running that way.
Blocks are cheap.

watch the 6 part video series with Tony Hewes at 4wd mechanix mag. Very interesting stroker info. I am currently Building mine based on the Hewes short rod motor described in the vids

I built mine 3 years ago, went the long rod, custom piston route. I spent about 2500 on mine, I already had the head. Ended up with a 4.7 that does real well! Jeep strokers web site has tons of good info!
