OK, just checking my memory here. What all did the "512" block come in? I'm going from memory, as I don't have my books here, so be easy on me!
1969
<UL TYPE=SQUARE>
<LI>L-71 Corvette
<LI>L-72 Camaro
<LI>L-72 Chevelle
<LI>L-72 Passenger cars[/list]
1970
<UL TYPE=SQUARE>
<LI>LS-? Corvette (what 454 was in the Corvette?)
<LI>LS-5 Chevelle/El Camino/Monte Carlo(was there a 454 Monte?)
<LI>LS-6 Chevelle/El Camino
<LI>454 passenger cars?[/list]
It looks like the "512" came in many flavors (2 and 4 bolt) and in many different cars. So, what did I miss
? Oh, and if you're worried about it being .060" over, just correctly sleeve it back and it's better than new.
