My Claytonized 427 (429 now) has AFR225s and although I barely have my break-in miles done, I can tell you the low end feels very potent. I was a little worried about drivability, even though Cory assured me it would be fine, but it's already more drivable than before. Even with the big heads and solid roller cam, it actually gets better mpg than when it was only 375 rwhp.
