does anyone know what this is the casting to?
D10E 6015 AA

Hello. That's a 302 block. If you look right above that number there will be a date code which will tell you what day that block left the foundry.Hope that helps.

Veronica's awesome, isn't she.

[astumpf]

thanks, i was told it wa a 289, but i didnt think 289s were made in the 70s

D10E should be a 1971 block

[EagleAutosports]

It's a 1971 302 block with an 8.206 deck height.

The 289 and 302 blocks are twins unless you look at casting numbers.Last 289 i know of was 68.

[astumpf]

yea, i thought that was about the last year for the 289

Hi again. Yup, the 289 was phased out during the 68 model year. And yes, that would be in the neighborhood of a 71 block. That casting number would appear on blocks used between aug of 70 up until around dec of 71. If you are putting together a numbers matching motor, the date codes would matter, if you just want a motor to put in a car to drive around in, you would get parts for a 71 model car, like the water pump, etc.. Hope that helps.
