From what I can gather, Mopar Performance (what you get at the Mopar dealer), had a 440 replacement block called the "megablock", and it had some issues and in 2007 Mopar Performance started using the "World Products" 440 as its 440 replacement block.

I was reading this thread:
speedtalk.com/forum/viewtopic.php?f=1&t=22174
and it pointed out that for racing, if you're allowed to use a replacement block that you buy from the factory, then you can use the Mopar Performance/Word Products block (which is much stronger than any block that came under the hood of a car that left the factory).
Yeah, how they read the rules is critical. If you go to the Dodge dealer and buy a block or a crate engine you're going to get the World block. The OEM blocks went out of production in 1978 so there isn't anyway you're going to be buying one of them except in a wrecking yard.
The situation is a little different for Chevy because the factory just kept building the big block in one form or another for a long time after Ford and Mopar shut down their big block production. Lots of times the rules are written by people who assume that everyone will be racing with Chevy motors.
If you can use a factory replacement block then you'll be fine. The new World blocks should be able to handle anything that you can throw at them NA. You can go 600 cubes and then run some Predator heads on there and make 1000+ hp if you have the cash.
It looks like the Ford 460 has a similar situation:
I don't have a list of all the rules for the Steam CEVS EVOC Monaco Challenge, but I think it allows any type of Mopar original, factory replacement, or aftermarket block, big block or small block.

Would your rules alow you to run a mopar performance block?? Its still factory..... kinda.
The rule used to mean that the block had to have been available in a production car or truck. There was a recent debacle in the club involving a mopar engine that was purchased to pull in the club that used a World race block. Last I heard they were gonna allow it because if you go to the dodge dealership and order a 440 replacement block that is what you get.

if this is the case we could have used an A460 block for the 557 I built for my friend. If you go to the ford dealership, the only 460 replacement block you can get is the A460 race block, very nice block and reasonably priced.
