  A:

  At this point in the engine rebuilding process, the home mechanic has several options available to him in completing the overhaul, and the main deciding factor is the state of the cylinder block, but has to consider factors such the cost, availability of competent machine shop, availability of parts, time, and self experience. Other possible reconstructions are to utilize individual parts if the engine block and components are re-serviceable; this may be the cheapest way depending on the nature of the damage, but it has to be checked extremely cautiously, particularly for the cylinder journals which demand new camshaft bearings and a finish hone. The master kit involves a reground crankshaft and matched pistons and connecting rods, the latter complete with new piston pins where applicable; the short block has a cylinder block with the crankshaft installed together with the pistons/rod assemblies, including new bearings and appropriate tolerance, to which existing components can be easily added. A long block, or Target or Target Master engine, is a short block plus such parts as the oil pump and oil pan, cylinder heads and valve mechanism, each of which has its bearings, seals, and gaskets replaced; it requires only the addition of manifolds and other small parts. To set a procedure to follow it is worthy to consult local machine shop owners, part dealers or the GM dealership parts people.
