Just curious about this. A friend of mine is being offered an engine out of a 1970 chevy truck. The owner said he thought it came with a 396 and they just 'rounded up' to put the 400 emblems on. I know chevy swapped over from the 396 to a 402, but they had spent SOOOO much money advertising the 396 that they continued calling the 402 a 396. I just don't have any idea about the 400.

I haven't seen it myself to see if maybe the truck came with a 400 small block, but he is swearing it's a big block and that it IS the factory engine.

Any ideas/information on this??
