A -0.040" undersize crankshaft for a 500 hp engine is fine. And it might even be debated to be technically better suited than a standard/standard crankshaft, but that's really splitting hairs and in reality one is not necessarily better than the other except for the amount of the crankshaft's remaining service life (future regrinds).
Don't worry that it's -0.040" undersize; regardless of journal size any crankshaft has to come out again if it gets damaged so it isn't important whether it's standard or -0.040". If you can get bearings for it, a freshly turned crankshaft may be considered a "good-as-new" crank in a case such as yours, and will last as long as a standard/standard crankshaft in your bulid.
Many, many, many Ford 460 cast crankshafts have been turned to -0.300" undersize (three hundred thousandths, or ten times a -0.030" under crank) and have been known to hold as much as double the horsepower you are referencing.
I've been looking for an engine for my 1953 F100 for a while, I still have the running original in it, but I may sell it or keep it for nostalgia. I bought 1986 302 EFI that was running when pulled for $365 CAD on a stand with a chain on the advice of my mechanic/friend. I really didn't want a...

I am brand-new to this forum, but I've been running a '69 Lincoln 460 in my '71 Mach I for 38 years.
There are not many other people running 460s in England. It's a great motor, but it does vibrate quite a lot.
I would like to hear from anyone who has fitted a Fluidampr harmonic...
My service manual lists the intake cam lobe lift at .252" (.436" valve lift based on 1.73 rocker arm ratio) and exhaust lobe lift at .278" (.481" valve), but the specs don't list the duration.
Does anyone know what the stock (truck) 460 cam's duration is?
Just wanting to know how much...
I am trying to order a stroker kit and trying to wrap my head around how to figure deck height. The block is a stock D9TE-AB there is no rotating assembly in it. I am pretty sure it stock deck height as I pulled it from a 50,000 mile truck. Would I need to reinstall the rotating assemble to get...
