First off I'm not quite sure if this is the right place for this or not so I'm sorry if it isn't.
Secondly, this may seem like an interesting question, but how does the performance compare between a stock HO 4.0L vs. a 4.2L with a high output 4.0L head with fuel injection? Basically my delemia is I need to replace the motor in my 1995 Jeep Cherokee Sport since it overheated and I would like to gain a bit of power while I'm at it. Would it produce more HP if I were to swap the bottom end of a 4.2L into my jeep topped with the top end of a 4.0L with the stock jeep MPI? Or is there something seriously wrong with the 4.2L blocks that would make it not an upgrade over the 4.0L?
Thanks guys,
