Don't rely on the casting #'s, they are not specific to any one engine.

The id pad on the top drivers front is the best way to spot either.

1964 Street Wedge engine will be stamped V 42 HP and a date below it somewhere. These engines were ALWAYS painted Turquoise.This engine had chrome valve covers and air cleaners with no snorkels and a tach drive distributor with no cable, just a cap over it. All were single 4 barrel intakes with a small 625 Carter carb and log style exhaust manifolds.



1965 426 Street Wedge would be stamped A 426 HP and then a date code below, same color engine. Both years carried regular 516 small valve wedge heads with heat cross over passages, nothing special.

Max Wedges were all painted Race Hemi Orange and had different font size stampings and characters. They varied based on which compression they came with. Here's a pic of an original Max Wedge pad for a comparison.
