Same block, the larger 4" stroke crank with a .030" larger bore makes it 408ci.

I just bought the house brand rotating assembly. Motors at the machine shop now getting the rods honed and the block line bored so hopefully they're good quality.

I have the ATK Block for my 408 project.

GET the TSP. Even though it costs more.
