Can some of you give some suggestion on a 3-core radiator. I went to the review but I don't think those are 3-core. Also a good place to buy the radiator.
Go to summitracing.com and check out their Griffin direct fit aluminum radiators for 87-93s. I think they are like $200 (maybe less). I have their NASCAR version and am extremely happy. The number of cores doesn't necessarily make it cool better.
I got mine from the local radiator shop. I paid 125 bucks for it. And yes there pretty heavy but my car cools really good. Get a Mr.Gasket 180* thermostat also.
