Radiator questions?
I'm bumping up the horsepower in my '79 Vette with the addition of a big block. It should be pumping out 450 horse on pump gas. What should I expect with regards to my cooling system? Is there anything else I'll have to change besides the radiator? I'm thinking about electric fans as well, with this car being street driven, is this a good idea?
Thanks if you can help guide me!

I changed over to a big block back in the summer. I kept the same DeWitt small-block aluminum radiator with dual Spals and I have no problems. Seals are critical.
