I am thinking of rebuilding my 292.  I am planning on using high ratio rockers, G heads ported and polished, Sanderson headers, new pistons (cast or forged don't know which yet).  The question I have is should I get my crankshaft balanced?  Is there a considerable increase in cost in having this done? I am planning on using this for my 60 3/4 ton 4x4.  I will be using it for some light towing, hauling and general driving.  Appreciate the advice.
