I know I'm late on this, but, Page 10, "The Buzz" in GM High Tech for the month of Aug. mentions a shop, no name, and an NHRA racer, again, no name, who is doing some stuff with an LS block thats 4.300" bore, and 4.400" stroke. Anyone got any info on this...is it real, when it will be available, etc?
