Radiators in an A-body?
The point in my previous post was to inform the OP that it isn't necessary to hack the core support to get proper cooling . A 22" radiator can flow enough coolant (if configured correctly) to cool any motor . Putting a 26" rad in without opening the core support is not increasing air flow . Sometimes it's the coolant volume that keeps an engine cool . I'm just trying to give the op options .
