My opinion.
Side  vents help at speeds above app. 70 miles/h for race cars.
Louvers are just a gimmick. help nothing, only cause trouble in rain=20
(mainly when car is parked somewhere).

    An old car should be fit for any normal drive, be it regularly or

    electric fan, either manually or thermostatically controlled.
    An aluminium radiator is indeed a gimmick and does not add anything at
    all. It will probably wear out faster due to corrosion. It is just
    cheap to manufacture and does not improve the cooling efficiency.
    What improves cooling efficiency is increasing the running temperature
    of the engine by fitting a hotter thermostat thus creating a larger
    delta T, fitting a more efficient water pump to increase the coolant
    flow, enlarging the total surface area of the radiator, i.e. more rows
    (up to a point), larger matrix or increase the air flow through the
    radiator, i.e. improved cowling, more blades to the fixed fan, higher
    engine idling speed but most of all a thermostatically controlled fan
    in combination with a carefully chosen thermostat and thermoswitch.

        When you use genuine parts to replace faulty ones and when you keep
        the car propperly maintained  and when you use the old car only
        occasionally for fun drives just to enjoy driving it, there is no
        problem with an old car.
        PS: Aluminium radiator is something nobody needs in a classic car
        as it improves nothing. Just a useless gimmick.

        Aluminum radiator swap update:
        Got my old oem unit out. Removed my nice newish metal flex fan.
        spliced wires onto the electric fan for easy connect/disconnect and
        then went to double-check the new radiator will work after and
        initial trial fit. What I found: OEM radiator is 1/2" wider and the
        aluminum radiator does not have tapped holes, so nuts will be
        needed to attach to my car. I am outside of the return window.
        So it looks like I will be getting my OEM Radiator flow tested and
        tanked.
        Will reinstall my flex fan
        refill with coolant/water
        have installed a new sleeved thermostat to replace the non-sleeved
        unit.
        I can make some shims for the new radiator, but cutting threads in
        the holes will most likely result in the holes being to big for the
        bolts.
