Script written and running.

bitcoind seems to respond to a getblock request pretty slowly, so it will take a while to scan the entire blockchain, but so far after scanning backwards through the 1500 most recent blocks, the one with the most transactions has been https://blockchain.info/block-index/388153/00000000000000a8dcc7b7f534b74c0e7e43686407e687217a1d10b40f0bea32 with 1,323 transactions. I'll post another update later when the script has made more progress.

Note: I am only scanning the current best chain. Orphaned blocks will not be included in this analysis.

Thanks for doing this! You should post your findings somewhere and collect donations! (I'll donate something if you do)

Given the fact that the smallest transactions are typically about 225 bytes in size, and the header is only 80 bytes, I'd think that the most transactions that could potentially fit in a 1,048,576 byte block would be somewhere around 4,600. That would require some extraordinary circumstances though.

Shouldn't be too difficult to write a script that will walk through the blockchain and find the block with the largest number of transactions and/or the largest blocksize.

If you don't receive a satisfying answer tonight perhaps I'll try and write such a script.

Maybe try over at Technical Discussion?

Edit; someone on Reddit claims 2.5k per block limit

Really, nobody knows the answer?

I found this block today that has 1200+ transactions (size ~700 KB), which is kind of what I was looking for. The max size right now is 1 MB right?

I haven't figured out how to find this information. The "number of transactions per block" chart on Blockchain.info shows the daily average, which is not what I want.
