camaronut if you run the 400 block be sure to lay a 400 gasket on the head you decide to run an drill the steam hole 3/16 in replacement head 2 per side this will keep it from overheating i ran these blocks for years on dirt track late model modified with good results i would buy 2 bolt blocks drill for 4 bolt sprayed caps 2 bolt blocks worked good for us factorf 4 bolt 400 castihg 509 and 511 seemed to crack in main webs if tou can find a 4wd blazer block without center freeze plugs that is the best block we have foubd hopes this helps
