I just blew up my 99 cherokee and I figured while I was rebuilding the engine it would be a good time to stroke it. I have been asking around and have heard that the 99 is not the best year for a stroker project.

If the 99 is a bad year for a stroker WHY
IF it is a good year what would be needed other than a crank and rods from a 4.2

I have about a $1500 budget and would love to get around 270hp
all machinest work will be done for around $400 so that leaves me with $1100 for components can 270 be obtained on this budget.

I think some of the 99's had the head that was prone to cracking.

If I switched the head to a different year would this solve the problem if so what year of head

I'm interested in this thread, i recently picked up a 4.0 out of a 97 that i plan to stroke as well and don't wanna dump any money into it until i know exactly what the quirks of certain year 4.0's tend to be, good thread.

99 is a good year. the 0331 head casting is the bad casting. it came in the 00/01 cherokees.

This is what I thought but a couple of weeks ago I swear I read something about some of the late 99's having the 0331 head. But I'm probally wrong. lol
