got bitten by the XJ bug. Came across one 2 door example that was bastardized in the past with lame 2.1 Renault tractor engine. 87HP

I have one 1994 WJ block on stock (that I bought for mj 2001 TJ stroker bouild) and I wonder if it will fit into 1991 XJ.
For sure I will have to source a whole set of attachments (brackets, alternator, starter, pump ...) But for a start - will the block fit?
