I'm lookin to by a 1996 4 wheel drive pickup with a bad oil pump (I believe engine is fried). I have a 318 out of a 87 or 88 truck. Can I make this work, or do I need to find a Magnum engine? Thanks for any advice.

you could make it work,with effort IMO a mag engine is much better for a swap,it will have all the plug ins and be a bolt and play weekend swap the pcm will have the correct engine to control,torque converter/flywheel will match up/ all the serp/belt accesories will be stock and bolt up correct... the pre-mag heads are a little diff on bolt holes for accesoies IIRC just ez-er IMHO good luck

So it's not as easy as swapping the top end? Well if thats the case and I have to go shopping for a magnum, what has to be changed besides a TC to put a 5.9 in its place?

good point on the mounts
if going from 5.2 to 5.9 you need the pcm for a 5.9 IIRC
Thats not entirely necessary. My 96 Dakota has a 5.9 in it with a 5.2 PCM running it.

Never been an LA with multiport injection. So, that means you'd need to swap the heads/intake/etc from the Magnum to the LA shortblock. Not to mention the motor mount issue. Be better off finding a Magnum in good used shape.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

No where to bolt a crank sensor on the older motor either.
A 5.9 will bolt right in there if you get the flex plate and damper with the 5.9. It will run fine with the 5.2 computer. I did it on a 2000 and it was fine, I eventually went with a mopar performance 5.9 computer and it really woke it up.

good point about the crank sensor! "Why won't this damn thing start??" LOL Also, if a 360 or Mopar PCM isn't readily available, you can have the 5.2 PCM reflashed through B&G Chrysler: http://www.bgperformancepcm.com/
