Does anyone know what radiator would be correct if the Build Sheet shows BR in box 46 on a 1970 Chevelle SS built in Kansas?
what about a PD radiator?
..For 1970,the standard Radiator for those three applications was the 3 row radiator,as well as the L-78 engined Chevelle.Transmission type did not dictate it.
When Air Conditioning was ordered on the L-34,or a 4:10 Rearend was equipped on the LS-5,LS-6,then they would receive the 4 row HD radiator automatically.But when the L-78 came equipped with a 4:10 rearend,it still was built with the Std. 3 row radiator.
