    Looking at aluminum radiators and notice there's 2 and 3 row radiators available . Is there better cooling with a 3 row ???? . I've heard that a 2 row is sufficient enough is this true ?????

    2 row should be fine if it has big tubes

    What I can tell you is you wouldn't catch me buying into that with my Firebird.

    Take a look at the factory stuff, either 1 or 2 rows and newer stuff cools great compared to our old cars.

    You must look at the low drag these new engines have.
    My old school Loose built SBC has to have 45 lb of TQ to break over the engine to get it to turn.
    The LS is closer to 20 lb.
    Short skirts thin rings.. and lots of oil usage :)
    I had to toss that in there.

    2 rows of 1" tubes is what I have and only a 19x22" radiator..that includes tanks!
    400+ Hp no issues with old school long skirt thick ring engine.
    Now there are many issues with some 3 row radiators as they are not all made the same.

    Core spacing could result in less cores and core width some import 3 row aluminum radaitors can have very small cores like .62" wide.. the 2 core would trump it with 1" wide cores.

    Do your research.

    I've been researching that too. It should have more surface area than the brass radiator since those are generally 3/8 inch wide which would total 12/8 or 1 and 1/2 inches(for a cheap 4 core it would be around 2 to 2.5 inchesif it were a more expensive I set up)

    This is a good read. I'm looking to get the griffin 1.5 inch tubes

    Let me know how this works for you @muscl car I am looking to order the same. I am currently running a factory shroud and a clutch fan so I am hopeful I can continue using those, but may look into swapping to an LT1 style fan set up if needed.

    And can you take pictures of the core innards? I am curious as to how they look compared to my 4 core.
    I really would like to continue using my clutch fan/shroud
