HELP ME!!!

i need help..i just bought a 63 rambler wagon and it drives good but looks like a diesel..will a 232 or 258 swap in without to much problem?  

What do you mean?  The engine smokes, or it really looks like somebody put a diesel engine in it?  What engine does it have?  I would think a 232 would have been one of the original options engines for this car, therefore it would be a very straight forward swap.  The 258 should be the same block in most instances and would be easy as well, I think.

You didn't mention which Rambler 63 wagon you have...American or Classic/Ambassador?  They have different dirvelines!  The Classic/Ambassadors have torque tube drivelines and can't be changed out without serious issues.  I believe the American body in 63 had an open driveshaft driveline..the later ones sure did.  
Regardless, I'm assuming that you have a 199cube motor.  An EARLY 232(pre 1972) should be a bolt in upgrade.  All 972 and later 232 and 258 amc/jeep engines had a different bellhousing bolt pattern to match the Generation2 AMC/Jeep V8s.  You have several options depending on what you have.  I have lots of parts that MIGHT help you.  Let me know if I can help.

Is your Rambler a Classic or an American?  
ITS A GAS!!!!!!!!!

The 63 Classic had either the cast iron or the aluminum block 196 in-line six.  The 63 American had either the OHV or the flathead (L-head) 196.  Pretty much the same engine block in all of the above cars, except of course the aluminum block engine.    A 199 or pre-1972 232 engine will drop in to either body style (classic or American) but you will have to use the short water pump in the American.  The bell housing bolt pattern is the same as the 196 so your existing driveline can remain in the car.   You will need to modify or fabricate the engine mounts because the 199/232 engine is shorter (vertically) and the engine mounts will need to be taller.  In 1964 the 232 was first offered and it was introduced in the Classic series, so factory engine mounts for that body style (63/64 Classic) were produced if you can find them.  

All of the 196 engines used the same bottom end (crank and rods), but different blocks. The general layout of all are the same though, I think that's really what you meant Pacerman!

The 196 has mounts that bolt directly to the crossmember (no "perches") and to the oil pan rail of the block. I used 3"x4"x1/8" thick and about 5" long rectangular tubing to make perches for my car (stroked 4.0L in 63 Classic wagon). Use the 3" side to raise the engine up, 4" side is drilled for the mounts. I drilled them for the motor mounts and bolted to the engine (5" length should be parallel with the crossmember, with the end near the edge of the engine side of the mount). With the tubing in place I lowered the engine in the bay. Make sure the engine is positioned correctly, then go underneath and mark the original mounting holes from the 196 mounts. Pull the assembly back out then drill and tap for a 3/8" fine thread bolt. I use lock washers AND lock-tite. Never had a bolt work loose! If you have room the drill and tap operation can be done with the engine left in place, but make SURE you wear safety glasses! Don't want metal chips in the eyeballs!! I used the engine mount side plates from a 74 donor 258 -- the one that donated its' crank and rods to the stroker. Engine mounts are for the same.
