i picked up a 2-bolt 454, bored .040 over, machine balanced and what not.. but i dont know what brand or type of pistons it has.. i tried contacting the shop that did the work for the original owner, not the one that i purchased it from. he didnt know either haha.. but i cant find any website that matches the number thats printed on the top of the pistons.. so any help on this would be appreciated

the piston number is > H426CP.040
