I don't want to burst anyone's bubble, but almost every crankshaft seller uses the cheap Chinese forgings for their budget crank including Crower,Howard, Eagle,Hawk,Scat, Ohio, etc. The list goes on. The difference is how well they are heat treated and machined once they reach the USA, O'H and one bad, your Bowtie block is cast in Mexico,(but atleast is not Chinese) The only real American cranks are the high dollar forgings or the Billet cranks.
Now to cut to the chase i sell ProComp products, i donot advertise them just word of mouth. i will not use them for an engine build,and will not sell them to a drag racer, (except starters, they are dam good), only for the street, i also recomment that anyone buying the heads do a valve job on them because i've had a couple leakers as bubbabbc and Carl Hink said, they also donot flow the advertised #'s. They do work o'k on the street, but i donot use their valves. If i sell a set i buy the good valves@ about $225.00 VS $108.00. With that said, i think they are o'k for the street but if you plan an all out race engine i would suggest you go the extra bucks. I personally use Dart or brodix.
These are my opinions only and i'm certainly not trying to sell anything, hell a few yrs. ago i bought a set of Trick Flow heads for my El Camino, still on it today, they run worse than the stock 1.94 heads. Advertising sells products but most of them are just not true. If you want to go fast, do what the other racers are doing and spend the extra bucks.
