i was just wondering if the forum has any engineers on bord. i had an idea the other night of machining the z blocks down about 1 inch or so then making a plate simerler to a adaptor plate for a carby going from the z block water ports to a rb20det head water ports, then welding it too the block, welding in the cylender walls and boring it back to normal specs (making it smooth in the bore again) would it be possible
