1) Rebuilding is replacing every moving part in the engine, and boring/honing/machining down the worn places. This would be valve seats, cylinder walls, combustion chamber, ect.

2)B&B, as said before is expensive. Not only because of the tedious task of measuring and weighing EVERYTHING going into the engine, but because most shops will have to buy multiples of the same part. A shop would rather have too much weight/size and trim down how they want, then too little. But too little always comes in a set of valves and springs and pistons... so the shop needs to order multiples, find the biggest ones, and when they have a complete set of larger items.. start cutting. That is a large chunk of expense.

3)I think bbp took that. If you want an engine to rev as high as possible, you better have it blueprinted and balanced (especially in a v-formation engine). This keeps the same reciprocating mass on both sides of the block. Also.. it allows better sealing on valves and rings, for better compression, and more power (marginally... but if you want every bit possible... you need it.) Balancing is the task of keeping everything the same weight. That isn't a problem. The shop will order 1 set of an item, and weigh them. Find the least heavy, and cut weight off the others to match. A simple balancing is costing me only $100 on my KA-T. The blueprinting part is measuring and so forth, and cost my corvette engine $2,400.

4)A rebuild can be done by you, but you'll need a machine shops help. Honing, boring, hot-tanking the block to remove all crap in it, ect. Also, they will need to press in the wrist pins on the pistons. Aside from that, a FSM and torque wrench is about all you need.

5)Any shop can B&B an engine. It's not complicated. But a specialized shop for that brand car probably has more hook-ups, and can get cheaper prices for that particular engine.

6)Nope.
