Also the 97 Cherokee has a 5speed and the 89 is an auto. I know the donor jeep it used to be my daily driver untill the auto tranny died and i believe it can keep up with the HO motors all day my friends used to call that jeep " Tilly" cause it's a roto tiller.

Yep. You'll be fine.

Well prob. Solved i just got a line on a 1996 HO motor to put in instead of the one out of my 1989. I think that will work much better.

I am curious as to why you aren't using your 89 engine. It will work as a longblock or shortblock. Is the thought of pulling both engines a bit much for you?

Well this 96 is an HO motor and im getting it for 100 so i dont wanna pass it up at that price

Good price if it has good compression in all 6 cylinders.
