DOES ANY HAVE THE SCOOP ON THE NEW FORD SPORTSMAN IV 351W BLOCK? IT IS DUE TO BE RELEASED NEXT MONTH AND IS PART # M-6010-C58. I HEARD THAT FORD HAS SUB-CONTRACTED DART TO MAKE THESE BLOCKS FOR THEM AND WILL BE RATED UP TO 900 HP. THE SPORTSMAN III BLOCK HAS A RATING OF 700HP. I CALLED FORD RACING A FEW TIMES AND HAVE TALKED TO A FEW DIFFERENT TECHS. I'VE BEEN TOLD 2 CONFLICTING STORIES. ONE PERSON TOLD ME THERE WILL BE NO DIFFERENCE BETWEEN THE III & IV. ANOTHER TECH TOLD ME THE THE MAIN CAPS AND WEBBING HAVE MORE BEEF TO THEM and THEY ARE BUILT WITH BETTER QUALITY STANDARDS. ANY WORD ON THIS NEW PART WOULD BE APPRECIATED!!!!!
