A 440 is superior in every way to a 413 and no one should ever waste their money building a 413 unless they're looking for factory correctness..... /thread
Apparently most folks can't swing a dead cat without hitting a steel-crank 440. Around here the trees are all dead and people are wanting $600+ for cast-crank smoggers that they say 'ran rill guud when we yanked it 10 years ago'.
I'd take a cheap, good-running 413 that I stumbled across over searching for a 440 any day of the week.
A 413 is a 440 with 27 fewer cubic inches. So, all other things being equal, it will have 27 cubic inches less horsepower and 27 cubic inches less torque. Plus there is no good off-the-shelf piston for a 413.
On the other hand, a 413 has 30 cubic inches more than a 383. With a .062 overbore, it would have the same size bore as a 426 Hemi (which no one accuses of having a "tiny" bore), and would have only 14 less cubes than a 440. And a 413's stock bore is larger than a stroker small block with about the same cubes. Finally, ALL 413's have forged cranks.
There are enough 413's still out there that I don't understand why KB or someone doesn't make a decent, cheap zero-deck piston for it, or at least for 426's and 4.25-bore 413's. That one part would make a 413 a much more desirable alternative to a 440. . . .
