Outfront Motorsports 775 Closed Deck Short Block EJ255 W/ D25 Heads LGT/OBXT 2005-2009 264°-260°/260° | 10This 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
