Another Radiator Question

[Tom Cimino]

I'm coming down the home stretch with my 302 to 431FE stroker upgrade in my E-M Cobra. I'm looking for opinions on if I'd be able to use the radiator from the 302, or if I should get a larger radiator.

The rad that is in the car now is a brass 4 row Griffen. The core measures
21"w x 17 1/4"h. Looking back to the the spec. books from E-M, they only offered this radiator or an aluminum "racing" radiator. There was no distinction between big block or small block. Inlet and outlets were spec'd for Ford or Chevy.

With the shroud and 16", 2700 cfm puller fan, the 302 never got hot with this radiator. I'm tempted to try this radiator, but I'm concerned that 1 1/2" inlet and outlet will be too small for the big block. Personally, I think it'll be barely adequate for the job.

The original plan was to replace the radiator with either a 2 row aluminum rad with 1 1/4 tubes, or a fluidyne Cobra radiator, but with the 30% rise in health care costs and Mr Bush's tax cuts expiring in January, along with working for a Fortune 500 company that is notoriously stingy with pay increases, I'm looking for options. Any thoughts?
