There are no hammered fenderwells with a 383. 426 Hemi conversion by Hurst-Campbell on pass fenderwell but not the wedge. Even the 440 in M code 68's and 69 fit. You have to have the correct exhaust manifolds but they fit.
Not 100% but I thought I read that the hemis were not hammered either. That the owner did it to make it easier for them to take the vale covers on and off, but was not done on the original assembly of the hemi cars.
