Outfront Motorsports V4 Racer+ Shortblock

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 V4 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. The V4 is a thicker insert only in the known weaker areas of the cylinder. This adds strength to the bore while not compromising cooling. This block comes machined for ½” head studs.
