So my 72 K20 came with a 350. I pulled a BBC 396 out of a 69 C30 years ago, had it rebuilt to be a 402 and it's now in my K20. I went with the 8 396 repro badges. Will post pics when I get them installed. Could have bought the 8 400 badges but I figured folks would think it had a small block 400 which it doesn't have.
