The Daytona Prototypes of recent years use the OE based GM LS9 block.
The block number doesn't have to match anything, just needs to be from the same OE engine family, or on the approved list. GM LS2 blocks have been sleeved down and used in LS1 stockers for years, much like the sleeved 454 blocks used in some 396 stockers. |

We used the lsx block in mine. Saw a significant icrease in power due to the very thick cylinders. It is heavy but in my firebird weight is no issue being rated at 381.
