The 62 409 was actually 409 hp rated.
The 63 was 425, with not much difference in specs, if any.
There's a perfect example for Dwight's previous post .
The 62 has been reduced through the current system, but nowhere near enough.
The single 4 , 380 /365 hp needs about 65 more off it ,with that small carburetor.
