    Description

    Featured in this kit are all the basic items you need to convert your small block 1970 Cougar or Mustang from a 20" wide radiator with a fixed four blade fan to a 24" wide radiator with 3 cores and the MAXIMUM cooling big block, high performance 7 blade clutch fan. 

    This setup was used on the highest horsepower drive-trains of the day including the Legendary 427 Side-Oiler equipped GTE and the 428 SCJ Drag-Pak equipped Cougars and Mustangs. 

    This might sound like overkill for your small block but keep in mind most of the motors out there these days have been rebuilt which means that the cylinder walls have usually been bored out resulting in thinner cylinder walls. Thinner cylinder walls mean more work for your cooling system. If you have AC, then the larger radiator is a MUST. In addition to this kit you may still want to purchase a new radiator cap and hoses. 

    This kit saves you money over buying each item individually and insures you get the right parts to do the conversion correctly. 

    Watch the video below to learn step by step installation tips and other helpful suggestions.

    Asked:
    at about 14:40 In the included video, he mentions getting a different hose to avoid bending the upper radiator hose to fit. Can you confirm exactly which hose he is talking about purchasing and using with this kit? Thank you.

    Tesrey Asked:

    WCCC Admin Answered:
    Repro radiators only come one way, automatic. You just have to cap the unneeded holes. Factory radiators had them without the extra holes for the manual cars.

    Why am I being warned about potential exposure to chemicals in motor vehicle parts?


    • Some chemicals in motor vehicle parts are on the Proposition 65 list because they can cause cancer and/or birth defects or other reproductive harm.
    • When purchasing USED or NOS items, we do not know if listed chemicals are present in these products.
    • This product is known to contain the following listed chemicals:
