413 Big Block

There are 413 pistons available in oversizes, but they're heavy, use 3/32" (BIG!!) rings, and they're like .080" in the hole. And I have yet to see any off the shelf new mfr stock bore 426W pistons...I'm sure they exist, but probably for reproduction purposes which means they'd be high compression and not so friendly with pump gas.

Making some SERIOUS assumptions here, and a dose of bench racing, one could have a stroker crank, (4.15") stock length rods, and the Speed Pro 383 flat tops would be like .030" proud of the deck assuming a blueprint 10.725" deck measurement. At least those slugs are readily available and not 1100g a piece. Otherwise, this discussion is academic :)

I'm not saying a 413 would be a bad choice, but when compared to a 440, where parts are more available, cheaper, and you get the advantage of cubes, the only advantage I can think of to running a 413 would be if it's in great shape and a 440 isn't available.
