400 blocks have siamesed cylinders with only steam holes for cooling. It does not work. Puffing smoke at 30,000 miles. Scrapped every one I got hold of.
yup! lotta folks tried rerouting water on them but never studied the science behind it, see a 400 here and there in street cars and a few strip cars bout it, never seen any body use one in circle track, mudd bogs or any high heat situation....
