AMC 360 swap

So I have a 1981 cj5. it has a straight six 4.2 that seems to run well but has some smoke coming from the pcv vent on the valve cover when I rev. the motor. I'm thinking this could be a pretty tired motor. I will be doing a compression test soon. but I just want to look at my options. I was thinking putting the AMC 360 in. I have been told it drops right in. just need to change motor mounts and cooling system. would this be my best option? not to big on the I-6. maybe you guys can change my mind. or maybe seal the deal for the 360 swap...

just looking for some opinions on the subject...

I swapped out a 304 for a 360 in a 78 CJ7 and it was a great torquey motor. I did GM TBI conversion at the same time, which was great for cold starts etc.

My swap was even more direct, didn't have to mess with the tranny, mounts, or rad, but I still think it's a great idea.

If you can find a 304 and put some 360 heads on it, I hear those breathe really well.
