i ask this because I currently just mounted a 2013 4.8 with 4L60 in my '86 and a friend was concerned that my idea to run a BB 2 core radi. and elec. fans would not be "suffecient" to cool the newer motor???

thoughts??

thank you again for your time....

On this '84, the opening in the core support is wide enough that the entire core is exposed to the air flow. The CU730 has a 28-3/8 in. x 20-1/4 in. x 2-1/4 in. Core. This radiator is the replacement for the OE HD cooling radiator for the BBC.

Are you working on a '72 model? The core support opening could be different. The Spectra Premium CU369 (replacement BBC radiator) would be a bolt in for that model and has a core size of 28-3/8 x 16-7/8 x 1-3/4.
