I want to buy one that fits, cools real well and doesn't leak. I was going to go Griffin Dominator but there isn't one that will fit and heard of leak issues. I am considering the 3rd gen Summit 2 core all aluminum F body rad. Perfect dimensions but I like the rubber heater hose block off. My current one has a leak and need one to properly cool a 9.6 to 1 iron head 350 and future 425 ci 403 based stroker. I don't want to spend $500 either.

 

I had a Modine 951 single row F-body aluminum, cost less than $100. In Florida, in the summer, unless I idled for a significant length of time, I did not even need to turn the cooling fan on. For the price, a no-brainer, IMO. And it's a tad lighter.

 

I had one of them and it cooled OK. I may price one out one but probably just about as much as the aluminum 2 core from Summit, if bought here. I pushed 220+ in heat towing with the Modine 951 with my 403. I want one that will cool the future stroker too. I had a plastic tank rad crack and leaked too. It was old but still...
