Four times Zion's age is 8 x 4 = <<8*4=32>>32.
So Zion's dad is 32 + 3 = <<32+3=35>>35 years old.
In 10 years, Zion will be 8 + 10 = <<8+10=18>>18 years old.
In 10 years, Zion's dad will be 35 + 10 = <<35+10=45>>45 years old.
Hence, in 10 years, Zion's dad will be 45 - 18 = <<45-18=27>>27 years older than Zion.
