A first feedstock is selected having less than about 250 wppm dispersed metals content and greater than about 5.24 API gravity. A second delayed coker feedstock is blended with said first resid feedstock so that the total dispersed metals content of the blend will be greater than about 250 wppm and the API gravity will be less than about 5.24.
