Where to find an MC?

["Chris Chindlund" <imageplus@socket.net>]

Since $ub$cribing to the List, I've determined that the only way to ever get
any real power out of my 85 4ksq, is to swap in a hopped up MC. ( I'd like
to have around 300HP to blow off Mustangs/Camaros, etc.)  So far, all I've
been able to figure out is that this engine is found in some 5k/200 models.
But which ones?  I'm sure it would be beneficial to find a complete car to
rob all the necessary parts from, but what should I be looking for?  Any
particular vintage better than the others?  What should I expect to pay?
(rough estimates, as I know this can vary greatly from area to area)
TIA
