I think this oil pan will clear, i've sold about 20 of them in the last 2 yrs. and not one didn't clear. I had them put on later chevelles but not a 64. They are also notched for a stroker up to 4". I'm not saying it will clear for sure but i think it will.
Zip.
PS, i'm not attached to this seller but have bought a lot from him in the past, including 6 oil pans at one time recently.
