Re: 1969 chevy cst big block
The 402 was introduced in 1970.
GM was developing the SBC 400, but didn't want a SBC with a larger CU, so they punched out the 396 to 402, and slapped on a 400 emblem to test our limits.
Course that wasn't enough, so on some they slapped on the 400 emblem, SPID read 396, and featured a 402 under the hood, and/or any variation of the three. Make sense?

With assys, the guide accts for 1000s details such as OEM identifications& part numbers, written in short order. 700+ images include assm, illust., charts, and points of interest. Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
