Without pulling it apart:
1.) Count the valve cover bolts. Ten on a Magnum, 5 on an LA (each side).
2.) Look at the intake manifold bolts- do they point straight up (Magnum), or are they angled to match the manifold mating surface (LA).
3.) Does it have just the LA "ear" type motor mounts, or does it additionally have the 3 lug mid-block Magnum mounts?
