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
