The 396 is not the smallest chebbie big block. It's the 366 heavy duty truck engine. Also, the way I heard the older guys at the chebbie dealer where I worked say......In late 69, there were several thousand 396 blocks "accidentally" over bored. Thus, the 402 was born and it replaced the 396 for the 70 model year. In small (Camaro,Nova) Intermediate (Chevelle, Malibu) cars, it was still labeled as the 396, but in big cars and trucks, they got 400 badges. Still under the hood on the emissions decals it said "402 cubic inches".

And again, NOPE the smallest chebbie big block was the 348!!!!!! It was the same block used as the 409 AND the 427 "W" motors! Exactly the same block on the outside smaller bore on the inside, the 427 however, got a different crank.

The 366, was in fact wasn't a "big block" at all! It was a long block, tow package motor......I had one of them years ago.....Was the biggest POS I ever seen in a Chevy Cheyanne Super, badged as a 400! Needless to say the small block 400 that was original to the truck blew, and whoever had the truck before me, replaced it with a 366.....
