thanks, the original 440 is lone gone when they pulled it back in the 70's. So I figured a Hemi would be the next best thing. I'm trying to keep it period correct and as origional appearing as possible. 4-speed and Dana are original to the car with just some re-freshing as everything has been sitting for 40 yrs. I did switch over the bell housing and starter to a Hemi bell w/ direct drive starter to keep with the period correct idea.
