3801730 Longblock Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured long block for the V8-350 and V8-380 aluminium engine, listed in the reman catalogue as fitting 2012 and newer. A Reman long block is defined as a cylinder block assembly with pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover, so the intake and fuel system, exhaust manifold, oil cooler, circulation pump and flywheel housing are not part of the package. It weighs 314.34 kg, covers 8 applications across the V series and consolidates four earlier numbers, 3801672, 3801671, 3801673 and 3801670. This unit is supplied on an exchange basis: core deposit 3804730 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
