I am getting ready to rebuild the front end of my car and I have been looking to put an aluminum radiator with electric fans in my 72 luxury lemans. But the prices are expensive for the brand new radiator with dual fans. I was wondering if a radiator and electric fans from the newer LT1 engines would be enough to cool my 400 that is lightly built with headers, flowmaster exhaust, semi high rise intake, mild cam and 670 cfm holly carb.
What rad/fan combo did you go with? I know exact replacements from companies like becool are going for too much IMO. I have this griffin universal that I've used for several years and it has the larger 1 1/4" dual cores and it is the one with the largest core, its still reasonably priced at just $279.69 just double check your measurements. http://www.summitracing.com/parts/GRI-8-00008/
Also the stock lower rad hose won't work, I picked an exact fit from autozone that I believe is for a sliverado pick-up. I'm running a single 15" flex-a-lite extreme black magic fan, like the one used on 5.0 mustangs that's built with a shroud that covers about 80% of the rad core. They make a larger dual fan that covers the entire core but it costs another 100 bucks and draws a lot more power.http://www.summitracing.com/parts/FLX-180/
The upside is that you'll only spend $600 for a cooling setup that you probably won't outgrow unless you build an11:1 600+HP combo. The downside is you'll spend more time making it all fit vs. spending $1100+ on a specific fit becool setup.
