This closed deck block design has been proven to withstand extreme boost levels resulting in high cylinder pressures without the worry of cracking a sleeve. The billet material that reinforces the combustion area has been further optimized with our V3 closed deck block in the known problem areas making it a far superior product to any sleeved block. With a closed deck block the stock sleeves are still in place eliminating all risk of dropping sleeves and pushing coolant that you have with a sleeved block.
This Block is rated to 775 BHP before adding upgrades.
This engine consists of the following parts:
New EJ257 case halves
V3 Closed Deck Process
Forged Pistons (Default is JE but you can choose other options below)
