I have a 67 HO and want to replace the stock radiator with an aluminum radiator due to cooling problems. I am looking at the BE COOL and Rodney Red models. Does anyone have any advice on these or any other models for this fix?
Couldn't resist a reply,,haha. Being a pretty hardcore circle tracker, needless to say we are pretty demanding of our cooling systems. We have used aluminum radiators before, solely for the purpose of reducing static weight on the front of the racecar, that, and eye appeal are the only reason to use aluminum. I am sure some have put them in and seen an improvement on the street, but I promise that is only because what they had before was not adequate to begin with. The hands down best heat tranfer comes from a copper brass radiator, with a HD high efficiency core and a perfect, not workable, but perfect, fitting fan shroud. As far as a 3 row core vs. 4 row core, that depends on your usage and if you have ac. I work very closely with a radiator builder in our racing ventures and have really picked up a lot of insight on cooling systems over the years, and always glad to help out. If you need more info feel free to drop me a note, as with work and family, I don't get to check posts too often!! Jeff, speedy_87ss@yahoo.com
Lahrz,I have a 68' with a 4 core copper rad, with a clutch fan,160 t-stat I never have cooling problems.I talked to Jim Wangers at the P.O.C.I. car show in G.Rapids 2 years ago he said that Pontiacs run best with a 50/50 mix of distilled water and green prestone antifreeze.Hope this helps
Just want to add more of the same good advice. I drive a .060 over 455 Pontiac in Southern California. I also went for the Aluminum, and after watching the temp gage soar most of the time, I finally threw it away and went to a 4-row HD radiator w/Copper tubes and brass fins. Makes all the difference in the world. Never goes past the T-stat temp. Also - I run an oil cooler which helps out.
