Need help Decoding 302 engine block.

[74broncoranger]

Just want to make sure this is the original engine for my bronco that was built October of 1972. Attached is a picture of the numbers I found passenger side near the starter. Would like both numbers decoded please

D20E-6015-AB

Checked a couple sites. I came up with 1972, September, 23rd day?

That's just the engineering number of the block. It's like a date and revision number. It has no bearing on the original application and could conceivably be from any vehicle that had a 302 from that time. It does say what year it was released and which vehicle line and division was responsible for that last revision to it.

D2 stands for '72 (C2 would be '62)

O means originally cast for Fairlane/Torino line, but like Viper says could have been used in anything.

Especially when you see this -

T = Truck (1958-65), Light/Medium Truck (1966-82), Bronco (1966-82, Except 1970-73), Light Truck & Bronco I (1983-later)

Except Bronco in '70-'73 There you go!

E stands for "engine"

6015 is just an engine designation

AB stands for revisions over the years

The engine date stamp will be on a pedestal below the distributor just outside the valve cover on the right side as you look at it from the front. will be 4 place alpha numeric code.
