CONSIDERATIONS FOR THE 4.3L, 5.7L and 350 Gen+ PARTIALLY DRESSED ENGINES:
To avoid the expense of a fully-dressed complete engine, the following items (if in good condition) need to be transferred from the original engine
over to the replacement engine: exhaust manifolds, risers, starter motor, alternator, pulleys hoses and belts.
Installing a partially dressed engine into a 1981 or earlier application would not be recommended. Due to the shift bracket that contains a reverselock mechanism, it would be extremely difficult and expensive to accomplish this upgrade.
