Magnum 5.2 into early A?
I just did the 5.2 magnum swap into my 65 cuda back in Jan...
(best thing I ever did btw)
The block is almost identical. Enough so that the swap was very easy.
The oil pan needed is from a LA 360 car. You'll have to massage it a bit for the centerlink. The rear main is smaller on the magnums, just like the old 360s.
I used the entire front end assembly off my 273 including the timing cover, water pump, all brackets etc.
The other things from the 273 I used were:
fuel pump
exhaust manifolds
motor mounts
distibutor
right angle oil filter adaptor
valve covers
Things I bought NEW were:
intake manifold
HV oil pump, pickup tube
cam extender / snout
gaskets - you'll need some for the 273 and some from the magnum
Hope this helps!
