    I emailed Champion Radiator and the one they list for Skylark '68-73 (EC-161) has the 3/4" tubes.

    They said the (AE-161) has the 1" tubes, but they are out of stock till October :(

    There is a dimensional difference between them:
    (EC-161)
    Radiator Dimensions:
    Total: 18.63" tall (19” with cap) x 33" wide
    Core: 17" tall x 28.25" wide x 1.75" thick
    Inlet: 1.5" driver side
    Outlet: 1.5" passenger side
    Tanks: 2.5" thick
    Tubes: 0.75" thick

    (AE-161)
    Radiator Dimensions:
    Total:
    18.25" tall (19” with cap) x 33" wide
    Core: 16.75" tall x 28.25" wide x 2.25" thick
    Inlet: 1.5"
    Outlet: 1.5"
    Tanks: 2.5" thick
    Tubes: 1" thick

    Overall the AE-161 is shorter by 3/8" but the same width.
    The core is 1/4" shorter, and is 1/2" thicker.


    Will the AE-161 fit without having to modify anything?

    Are they both aluminum? Aluminum will cool better then brass.

    Both aluminum. But the one they sell for my car is 3/4 tube and from what I've read here, 1" tube is the min I would want for aluminum.

    I just don't know if the slightly shorter, but wider one will fit without mods.

    Get the 3/4 tube if it’s in stock . Don’t think the 3/8 will make much difference,

    I disagree. The whole point of using aluminum is for the bigger tube sizes. Get the right radiator. The AE161 is a nice radiator for the money. If it was my car, I'd get the best I could, 2 rows of 1 1/4" tubes, it's the ultimate.

    Will it fit though?

    I don't think they sell anything close with 1-1/4" tubes. I asked for 1" or 1-1/4" and they came back with the 1" model

    Yes, I believe it will fit. I seem to recall other guys using that radiator. If you search here, you'll probably find some threads.

    The plastic tank HD version 1800Radiator has will do the task exceedingly well,...for $165

    I live in SC,..IE the surface of the sun during the summer I have put them in customer cars,..they are in all our cars,..I never see over 200 sitting in traffic

    Out driving with normal stop and go,..you'll never see over the Tsat rating,..just my experience,..be it aluminum heads or iron heads

    Just ordered this from Jegs to replace the one I put in a while back. In the process of building new motor and inside was starting to build up too much scale. Don’t want to risk running too hot. Universal fit but very close. Just have to modify rubber cushions and use a Chevelle lower hose to fit the larger bottom outlet. 83076129-00BA-458A-BD6D-D0E7595BD0B0.jpeg

    That's looks great and a good price too, but you must have a manual trans? No cooler line in/out.

    I want to thank everyone for helping me out with everything, and I mean everything!

    Thank you :D

    I've had replacement plastic side tank radiators before in my '97 Silverado and I didn't have much luck with them not leaking. I think I'm going to wait until the AE161 comes back in stock. I think that's the best quality option without breaking the bank.

    The only down side is I will probably have the car up and running with the OEM radiator before that, and have to swap it out when I get the new one. Not really a big deal for a month or so. I never had any cooling issues with the OEM, but I want better for this build.

    I used to trailer a 19 foot fiberglass bow rider 100 miles (200 Rd trip), with the GS every weekend during summer, for two years with the original Harrison. You'll be just fine.....

    I have a four speed, but they also make it with an oil cooler at a slightly higher price I’m sure.
