I have a 69 corvette and it will never be a stock set up. I am customizing it but it has a 350 in it now with a soon to be 383. The radiator support was rusted out and the radiator a mess. I plan on going aluminum with electric fans but here lies the question. I keep seeing BB radiator or SB radiator support on the products description. What is the difference? Can I use a BB radiator set up for the 350 engine? A BB core support for a SB radiator? Any help would be great since I can not nail down the difference's or find info to explain it. Yes I am a noob but willing to learn. Thank you guys.
