Re: 305????

For stock engine in an '84 several clues:
-5.0 H.O. emblems
-dual inlet air cleaner
-electric fan
-electronic spark control box
there were several other differences vs. the LG4..
Earlier ads for this engine option stated it was rated at
190hp,200hp when premium gas used-some tests back
in the day suggested engine actually put out closer to
220 hp
