water blocks

Hey I need some opinions on waterblocks. I have found some KB blocks but they are not solid they are waterblocks I want too run 4.5 stroke and 4.310/4.375 bore will these blocks be strong enough and durable.

 

What are you going to compete in?
How big of blower?
How fast of RPMs and will you want to run it on kill?

 

water blocks was all connie kalitta ran for many years,, we still run water blocks it is really not a (water) block the reasoning for it was to shed some weight, we have a 4/5 stroke 4.310 14-71 running in the 5's 9,800 at the stripe..Dave
