304-->392

["CDesPlanques" <adesp@domain.elided>]

My '77 has a 304 in it (I thought/was told, it was a 345).  A few pushrods jumped ship and were mangled.  I don't know why it
happened.  Just happened when I started it.  All on one side( pass.) of the engine. Any Ideas?? What damage could I have done to the
engine (more specifically the short block I may get new heads).  I intended to rebuild it, but then I saw a 392 for sale in the
paper.....hmmm....It is from a '73 pickup, does this engine have a EGR valve and the other '77 emissions equip. , or do I have to
get a manifold from say a 345 that has an EGR valve?  Everything else it the same thought right? I know the water pump, etc. are the
same, but will it have the double hump oil pan, or will mine from the 304 fit?
