A 402 is really a 396, bored .030 over, already. .120, is about all there is before you hit water, so, another .090. You can sleeve the block, and go further, however, at that point you would be better to with an aftermarket block.
No, they made a small block 400 and a big block 402. However, Chevrolet DID call the 402 a "400" in certain applications. They also called the 402 a 396 in 1970 (the 402 is a slightly over bored 396) because of they reputation the 396 had built in the SS396 Chevelle Super Sports.
The 400 Chevy is a small block engine. The 400 BIG BLOCK Chevy does not exist! 402 big block Chevy does. it seems in the early 70s Chevy put 402s in their pick ups and they had 400 badges. this opened the can of worms known as the non-existant big block 400.
Yes, however you will need to use a 427 crankshaft, rods, and pistons.

There are contributing factors, however, about 6 degrees advanced or BTDC., should work best.
First off, the 402, is just a 396, bored .030 over. The HP rating will be aroun d 300, to 325. It is a torque motor, more than a horsepower motor.
It depends on what year it was made, and what it was installed in. Chevrolet never made a high performance 400 small block. They used the 396/402 for high performance applications. The small block 400 was typically installed in heavy cars like station wagons.
