For those that aren't on some of the other sites I'm on, I pulled the motor out of the Chevelle last Sunday and during the week slowly pulled it apart except the crank, rods and cam.
I found out that the motor has .060 over 12.5:1 pistons with 840 closed chamber heads. Now I understand why it ran better with a 104/93 fuel mix. The crank is cast iron with standard rods. I have a couple 6223 cranks but probably will be looking for a different set of rods. I'm still on the fence of building this motor or taking the 512 2-bolt main block I have and building a 427. ![]() Here are some pictures. ![]() ![]() ![]() ![]() ![]()
