    Yes

    Kalitta ran water blocks right up to the point that NHRA mandated forged blocks - So that should not be a problem.

    Most KB blocks were called water blocks even though you could not flow water thru them. Do you need water flow ? Call Keith Black they seem to be able to help with most questions regarding their product.

    Water Block

    I have a "KB water block" as a spare motor. It used to be my only motor. Never had a block related problem with it. Of course, we never tried to rotate the earth or anything with it, either. Having new cam bearing put in it this week for a rebuild. Roots blown fuel headed on alcohol in a dragster. Just saying.
