I thought all big block trucks had the 402 starting in 1970 and were badged as 400. I also just picked up an all original 1970 big block truck a week ago and it is badged and labeled on the SPID as a 400. Were trucks labeled as 396 and 400 in 1970. I know GM still marketed it as a 396 in 70 but didn't label it as such (as far as I know) in 1970 on the actual vehicle.

The only reason I ask is because my 1970 SPID says 400 cid v-8 engine and your 1970 SPID says 396 v8.
