Radiator Tag

[Keith Tedford]

I have a big block radiator tag with the following information:

IA BQ
XJ
4

The BQ is twice the size of the other letters. Does anyone have the Harrison Radiator information on this?

I show BQ code for 1970 Chevelle and Monte Carlo with 402/330HP (LS-3) with Manual trans.
Also 1970 Chevelle LS-6 with Manual Trans.
This is a B/B Heavy Duty 3-Core radiator.Meaning it has a 4-core Passenger side tank,but the 3-core drivers side tank.
This is not a complete Big Block 4-core radiator.
