H is August right?
I would have to guess that the foundry would have started casting blocks and heads in May or June in order for the pipeline to be full of engines to support building cars mid-July.

Correct, H = Aug so that block was cast on Aug 19 1969. The papers I have show D0AE-A, C,E,G,J,L all with two rear drain holes ( see pic of a J block I had) All these were designated as 1970 blocks, but cast earlier. Those same casting designations also show up for 1971, with the exception of J, so the date code is the deciding factor. 71 blocks had the drain hole crudely cast in the front of the valley and the rear holes removed.
So there may have been blocks cast way before your Aug block.

Great info, but this is still an early casting, right. Have several blocks 2 and 4 boltet, but this is the "oldest" Cleveland I have seen. Thanks for information.

I don't know for sure, just a guess, but A through G could have been early development (prototype) blocks. J is the earliest I've seen too. Some other members will have far more knowledge on this.
I’m currently looking for an early cast block and have 2 other blocks that are D2AE available for sale or trade.
Anyone have a block cast in Dec 70, Jan or Feb of ‘71?
Thanks,

Probably a question Kevin Marti could answer if he can find the first 70 Mustang serial# with a 351C. Figure the block build date would be around 20-30 days before that...
Is there a readable vin stamping on yours?

A mid-August block would likely have ended up in an early September build car. It's an early block, but there were likely many, many thousands cast and built before it. Vehicle production started in late July, and there were three plants building Mustangs. The 351C also went into Torinos, Montegos and Cougars in 1970.
