I need some information on which fan shourd I need to use. I am putting a BB in a 67 camaro & have a 23 inch 4 core radaitor I am running the 67,68 style big block frame mounts & 69 style water pump & pulleys. Which fan shourd do I need to buy 67 or 69? Thanks Johnny
The question is what year radiator you have, if after market I would go with an electric fan. But if it is a '67 radiator then check the diameter of the opening. I know on my '68 the opening for a smallblock is 20 inches and I am using an 18 inch flexfan. the key is to have enough of the fan inside the shroud ( spacers may be needed ) to pull enough air to cool the engine.
