Paging Tom Dewitt
Tom,
I have been real happy with the Griffen radiator I bought from you a couple of years ago, it keeps my 620 hp 454 cool even in So Cal heat. I am upgrading to a 598 in 12.5 to 1 motor. I am wondering if this radiator will keep this monster cool. I have the 1.25" tubes and dual spal fans, with the plastic shroud. I plan on adding an oil cooler also.
