400 cranks
I just picked up 3 M-blocks from a friend. I tore all of the pans off of them and all of the cranks had 1KA stamped on their counterwieghts. I was told that if they had 1K on them than they were 351 cranks but my friend said that he was 99% sure that one of them was a 400 cause it came from a truck he had that came with a 400 origonally. that same one also has a thicker harmonic balancer on it so I thought for sure that it was. Could somebody check and double check to make sure that 1KA is a 351 crank?-Thanks man
