Have I been wrong all these years?

I thought that big blocks were 396, 409, 427, 454....??

The 400 came in both versions...small block and big block although not in the trucks of this vintage....only later on in the mid/late 70's.
The '400' notation on these trucks defined a big block 396 bored out to a 402...but they still used the '400' designation as a good/quick default.
I think the 396 (non-bored) trucks ended in 1970...then they starting the bored out (402 ci) version....still called it a 400 tho'.

My two bits.
