04 450r Engine Build

[HMF_2004_450r]

I recently locked up my 2004 trx450r crankbearing went out had a hot rod crank in it the guy who i bought it from had that and a 13:1 wiseco piston also.
the bearing went out wiped the walls of the case out and scored the piston and cylinder got both case halfs. im rebuilding it myself and i was wonder what would be the best setup to go i defiantly know im going 480 im trying to figure out whether athens or cylinder works and whats the number 1 crank out there so this doesnt happen again
I drag Race And i want to know whats best for that

Hot Rod crank, works well, with OEM crank bearings. If you have the coin, use Falicon crank. No matter which way you go, use OEM bearings. Do you know what brand of bearing, was in the motor?
