Not Ranked
I've never heard of anyone using cement in a block. My block is half full of the Hardblok. The Hardblok stabilizes the crank and bottom end. I drive on the street all the time, on the freeway engine stays at 170 with no fan, when I'm in the city, temp might hit 200 with the fan on....Don't see any need for it, if you're not turning some high RPM's
