Stumbled upon an old mopar with a big block and my mind blanked while trying to ID the engine...

Car in question is a '65 sport fury convert, factory big block car. My impression is the big block engine options available were the 426W, and 383 2bbl & 4bbl....and all would have been turquoise, correct?

The only numbers I could get at were on the ID pad located on the driver side of the engine, leading me to believe it's not a 383 (only the RB engines had their ID pad on the front driver side of the block, in front of the intake manifold, right??).

I've attached a couple pics...including the ID pad, the carb ID tag, and the whole engine.

I'm thinking it might be a swapped in 413..??
