It's curse like 383 is that there's still a bunch of 400/440 around making less sense to build just like 318 and 360.
The 413 is like a .065" overbore away from being a 426 which seems to be the right size to make 500-550 hp, I guess why a lot of people build 408-416. Ford and Chev peeps love their 427 we should be more open to the 413/426.
