There are various changes that were made on the 4.3L engine throughout the years. Listed below is a link that will assist you in choosing the correct longblock for you application. Technical Tips. This is a 1996 and later new longblock as intended to replace the Mercruiser, Volvo Penta, and OMC versions. These Vortec style engines can be identified by the aluminum oil pan and the (8) bolts used to fasten the intake manifold to the cylinder heads. The engine can however very easily be used for retro-fitting earlier engines down as far as 1986 by simply re-using your existing harmonic balancer.
