Tech Question
Jeff Sorrell, Kernersville, NC, 60's, 413
I'm a Mopar car nut and recently my uncle asked me about the 413 engines. He has a chance to buy one that came out of an early sixties model Dodge station wagon and wants to know what it's worth. The vehicle had low mileage. Any info you can give me will be greatly appreciated. thanks, Jeff
Jeff-
With the exception of the 1962 Max Wedge engine, most 413s were small-port torque engines. There's absolutely no reason why a set of better cylinder heads couldn't be bolted on, along with a hotter cam, etc., and then you'd make some HP. But the problem is, value-wise, that it's just as easy to build a 440, which is just as stout, takes the same parts, but has the advantage of a much larger bore size to begin with - not only creating the larger displacement, but allowing larger, and unshrouded, valves. Better breathing = more HP.
All 413s came with forged steel crankshafts, and, once it passes a Magnaflux test, this is a worthwhile piece. It can be swapped into any 440 block, most of which, in the mid-late '70s, came with weaker cast-iron crankshafts.
Pre-'62 413 used a completely different crank flange setup (8-bolt, greater offset) and those have little value except for pre-'62 restorations.
Bottom line: if it's worth $200, that's a lot.
