Time for a new radiator for my 77K20. Who do you all recommend for a direct replacement?

Went from a standard 2 row to a Champion 3 row aluminum BUT I had to fabricate the top and bottom rubber mounting insulators. I ordered 2 different sets of mounting insulators from LMC and made them work. I cannot remember which insulators I ended up using :(

Get a good rad shop to recore your tanks. Pricey but the best way to go imo.

Some (many..?) rad shops say you can't get copper cores anymore... so go find another rad shop because they are just too lazy and/or don't want to stand behind their work... which they would need to do if they made the rad.
Easy money to change out to new parts I guess...


I realize you're asking about aluminum rads... I just never recommend them. I find they are too vulnerable for trucks... if you happen to drive like me for example.

What's vulnerable about an aluminum radiator? I've never heard anyone recommend against them before.

Im using KKS three row aluminum units from ebay in two of my trucks. Had to do as Sublime said though and get crafty on the rubber mounts. The radiators are good. Run cool and have been trouble free. Also look damn good.

If you want a low buck solution you can use a cu730 radiator from spectra and its only about 130 bucks shipped through Amazon, but I am sure you can find it at any chain store. It's an OEM replacement for 99 - current gm trucks, and it'll probably out flow most of your old school 4 core radiators. It's very popular rad for LS swaps in Squarebodies, but I see no reason why it would not work well with a stock motor.
