Hi, I installed a 454 in my 1986 c10. It had a 305 in it. My question is what radiator sizes will fit and also does anyone have part numbers for the brackets for the power steering pump. I need those as well.
Thanks

Just in general, you can call an auto parts store and ask them to cross reference the parts to the vehicles / engines to see if its the same part number.

Use a mid 80’s 1 ton truck with a 454 and HD cooling option as an application.

With a bigger radiator you’ll also need the brackets and fan shroud. A 7 blade fan with a severe duty fan clutch is always a great upgrade.

I guess I was hoping somebody could tell me a radiator they used from another year of square body that worked for them possibly?

I thought I did that except for specifying a year (‘81+ interchange).

I have a huge 4 row radiator in my Blazer but it’s from a CUCV so parts places can’t look it up military trucks. I could tell you it’s the same as the same year civilian truck but thats as “vague” as my first post.

Note: diesel radiators have different size hose necks that have to be dealt with to fit a gas engine.

Welcome from Austria.
You can go to an auto part store, look it up online on Rockauto or Summit or Jegs or use the search function in this forum.
Brackets and other stuff junk yard or ebay or any market place.
