340 ta block whats it worth
The 340TA blocks were service items as well. I bought a 340TA block from Kenny (Keith's son) Black back in the early '70s when I broke my 340 block through a lifter bore doing something stupid. Kenny and I were in the same National Guard unit back then.
When I went down to Keith's shop in South Gate, CA, to pick it up, Kenny pointed to a stack of 340TA blocks and said, "Pick out the one you want."
The 340TA blocks have a higher nickel content than standard 340 blocks and thicker oil pan rails - don't have the reliefs cast in the inside of the standard 340 block oil pan rails.
