    Anyone recommend a direct exact fit replacement aluminum radiator for a 1971 Z28. I want to keep the stock fan and two piece shroud and have the top cover fit right and the radiator sit in the core support properly with the rubber bumpers. Exact fit replacement.
    I have a big block 70 SS that is on it's 3rd al radiator (Champion CC162, Griffin 33-145985-1, Afco AR80255N). None fit with the shroud.
    Thanks for recommendations.

    I don’t have a big block but here is what I just installed. I wanted a factory looking radiator and upgraded from the 20 inch factory radiator to the 26 inch , I found it on eBay it’s a KKS radiator under $200.

    This is what mine looks like. I installed electric fans but still use the factory top plate and original rubber bumpers.

    Z28’s in 70-71 had 2 row core 26 inch wide radiators. Big blocks had 3 rowcore or 4 row core (heavy duty radiator option) 26 inch version.

    My car is not a factory Z28. I opened the core support and installed a 26 inch radiator for future A/C install.

    The aluminum radiator I show above is a three row core.

    I put a Frost Bite 3 core aluminum in my 1971 Z28. Perfect fit...stock fan, two piece shroud, core support, etc. Dropped right in. It never over heats and has automatic trans cooler. Bought it from Summit for around 270. Part # FBR-FB163 - Frostbite Performance Cooling Aluminum Radiators
