I'm probably not qualified to offer advice on what radiator you need. I'm running 2 radiators on my blown 292. My primary radiator that's in the grill is polished with 2 / 1 1/4" wide cores and a 3300 CFM chrome fan. It was a little over $800. My secondary radiator is a Ron Davis drag radiator that mounts under the truck with a Spal fan and a Mazire electric pump on it. Pump and radiator about $1000. This radiator is primarily to cool the engine after it is shut off. It will turn on after the engine is shut down for heat sink. Will have manual for traffic jambs in Death Valley. So now that we know I'm not normal I think it's as important Where we buy as what we buy. I try to buy American even if it cost a little more. I also buy from places that cater to classics. I would rather keep these guys in business. One of my favorite things about the entire classics community is the diversity and comradery. It may be the same product but my money is going to an established supplier not some guy transferring my order that may not even know what a classic is. Sorry so long just my $.02 worth. Thank you for your time.
