I used to think so as a younger lad....Hearing about max wedges, and the beach boys 413 song against a belly button...No good pistons for them 15 years ago. They cost more to build than a 440 due to lack of pistons...Had mine in a 69 340 dart...Ran at BIR......stock form--could only get 14.4 qt mile.......cast iron logs however,,..Similar set up with stock 340 and same cam (484's) that ran 13.5 with its logs as well..

I went to 440's---413s have the same steel crank--so take that--and the rods.....Why would you settle for a smaller bore? with no pistons...all things being equal?

440's will out torque them and make more hp--guaranteed....(Not talking max wedges)

413 was great in my 65 chrysler....with 180k miles--could still smoke that rt rear tire...and get about 15mpg....but the heads are the junk 516's and a crappy intake in 65
