Re: Best brand Radiator for a 383 stroker
Thanks for your help, Were the Champion radiators a direct replacement or did you have to do any mods, also how many rows to you go with, My stock one has two rows but I'm thinking that won't do with this engine, I was thinking a four row rad would be better.

I have a 383 in my 70 stepside and I used a Frostbite aluminum 3 row radiator. It fit perfect and no cooling issues.

Last one was last year in Otis my 70-1 ton, I opted for the twin electric fan 1000hp cooling capacity version, I have no where near that kind of HP but with factory A/C and hot Kalifornia summers I got plenty of cooling. |

Re: Best brand Radiator for a 383 stroker
My 3 row champion is great but the upper radiator mounts from my old 4-row are a bit floppy.

Re: Best brand Radiator for a 383 stroker
I would just like to add this since you have a warm 383.
A radiator is only one portion of a ideal system. Before you install it I would seriously consider adding 4 corner cooling to the manifold. This is where you drill into the rear of the manifold, and tap or weld in atleast 6an line to the thermostat area. To which you buy the thermostat adapter so it screws right in. Just one of the many brands you can choose. https://www.jegs.com/i/JEGS+Performa...RoCw4EQAvD_BwE It helps prevent cooling issues in the form of hot spots. Which is air or steam being trapped in the rear cylinders. Which can cause pinging because the rear cylinders have tendency to run hotter since water, but more importantly air or steam can't get out fast enough sometimes. I am a big fan of it myself on anything I plan to run hard for extended time, and have even done it to a stock intake manifolds for trucks. So if I worked them I felt a bit more confident when hauling. It kept my 60 over 350 workable, and helped my 525hp 400 sbc keep from over heating when ran hard. Both engines are on the extreme end of DD, and it made quite a difference for me when they likely would of had a issue. When I have done it either for me or friends. I used a high volume water pump, but that may not be necessary. A stock one is very capable, and it was likely way overkill. |

Re: Best brand Radiator for a 383 stroker
This thread has good pics about 1/2 way down.
https://gbodyforum.com/threads/best-...p-gauge.59913/ This one uses a T in the middle, and I have never tried it this way. https://www.speed-talk.com/forum/viewtopic.php?t=23070 I couldn't find the Car Craft article that convinced me to try it, but I dont have any pics of when I did. All in all it does not add power, but will allow more even cylinder temps. If your engine is Hot enough. It can make a bigger difference. |

Re: Best brand Radiator for a 383 stroker
Yup. DeWitts if the question is the BEST. Best value radiator, the Champion appears to be a good product. Used one in my 240Z. Have a big block conversion DeWitts for my 64 Vette with dual fans. Most expensive car part I ever bought that wasn't an engine or transmission. I am inherently frugal and for my application thought the DeWitts the best buy.

Re: Best brand Radiator for a 383 stroker
Some things to look for:
Aluminum, large 2 row all tig welded no epoxy or glued tanks. Wall thickness is most likely the thing to look for. 4 row, copper and brass. Spendy yet on an older Gen 1 block you will find this is the way to go. There are tricks with cleaning an older system, copper and brass radiator, all iron block and heads. Try to get one of the newer aluminum ones clean is a chore, techs always recommend a replacement when maintenance was neglected. |
