Want to upgrade to a BBC 4 core radiator, what is needed?

Looking to upgrade a 76 C10 to a BBC four core radiator. The truck currently has the stock 350 engine and stock radiator.

Will I need anything else besides the following parts?

New rubber pads

New radiator mounts

Thanks in advance,

Wes

And possibly nut serts for the top of the core support.
My 77 wasn't threaded on the topposite of the core support.

You will get better cooling with a modern 2-core aluminum replacement. Instead of 4 small rows, they have 2 big rows. Air flows through them better and they have a better BTU rating. Even the cheap alum/plastic replacements from your local chain auto parts will work. I have one in my dually cooling my 454 and I have no issues keeping things cool while towing with the A/C on in Phoenix in August.

Spectra Cu730 radiator is a direct replacement for the 454. Works great
