So if i get the fiat 850 i have been looking at i need a engine for it. I just checked out the old engine from my MGB GT and it has glose to no compression so i don't want to rebuild it. Would a 4.0L V6 engine from a "98 jeep cherokee work? Im not sure if it will fit but if it does will i have to do any modifications to the tranny, axle setup, or anything else like that.
