Please don't confuse it. Yes there was a 400 small block in Impalas but never in trucks.

You and I both know the 402 was advertised as a 400. The emblems say 400. The SPID says 400. It's a 400. Internal displacement often doesn't exactly match marketing designations.

Besides, if you do the math, it's not actually 0.030 over. I'll leave that as an exercise for the reader.
