I have the exact same Motor someone gave me from a 88. Considering the exact same thing. What was interesting is that the heads on this one are 083 castings with a 73 stamped in them. Makes me wonder wonder if they are 73 cc chambers as they looking a bit smaller in that area.

Some say these blocks are capable of 500 ponies.
