It should normally be an 3 core with that combination.
Do you have a Buildsheet with callout?
When the LS6 Came with either an M-22,or a TH400 trans.& a 4:10 Rearend it automatically got a 4 core Radiator.
The 4:10 was the distinguishing component for them.
1970 LS6 Radiator Codes:
3 Core
BQ-Man. Trans
BR-Auto Trans.

4 Core
PA-Man Trans
PD-Auto Trans
These suffix codes were stamped onto a tag on the Passengers side tank.It was a seperate tag from the Radiator tank.
