i my self found the 440 block made late with the same thick mains ans the wide supports under the jugs as the 400s (but not the monster thick ones) it has to be better than the stock 440 block. i am not leagle to go faster than 10.s so i just hope this one does not crack. some day i will do one of these combos.
