My radiator just sprang a leak and I am looking to upgrade to all aluminum. Should I purchase a two or three core radiator? I have a 305 with dual electric fans and a 160 thermostat. Any suggestions are appreciated.

 

Do you plan on doing engine upgrades that would require extra capacity? From what I researched here, the original aluminum core/plastic tank radiator does a fine job of cooling the car. A replacement radiator might do just fine if your car is stock.

 

Nothing much done motor wize. However my little b. Irother works at a engine machine shop and he's bubuilding me a 383 with all the bells and whistles. I also like to upgrade when I can.

 

I got this one a couple of years ago when I upgraded my 305 to 355 and it has been great so.

It bolts right in with no modding needed. There are several stores on eBay selling it, I got my locally from some selling them out of his garage. Highly recommend it, all aluminum no plastic.

 

I plan on getting it on ebay. i just have have the ? of 2 or 3 core. i heard 2 core is all that is needed, i just want some more imput on the differance between the two.

 

That link says the radiator is for a 2.5L4/3.1 v6 Camaro or Firebird
Maybe its a different part # your looking for ?
"Very" nice radiator !

 

Well unless i hear otherwise im leaning twards 3 core.

 

My 414 solid roller LS motor was kept cool just fine with a dual core radiator from Entropy. The motor made 740 at the flywheel and turned 8k RPM. This was in 100+ texas heat.

 

The 2 & 3 core are about the same price. would it hurt useing a 3 core?

 

I have a 3 core and the only problem I have is on a cool night, heat in the car will kind of suck. It happens but I'm also running a 160 stat. I could fix that with a 180 stat but the car doesn't see alot of driving and its pointless to switch it for the once in a blue moon nights that I drive and it happens to be chilly. The good thing about a 3 core is that you can idle in chicago traffic on a 105 degree day and the temp stays at around 190 with the fans coming on once every 15 minutes. Just remember to keep your airdam intact and once you get moving, the temp will drop to 160ish and you'll be golden.

 

Thanks for the reply. that was what i needed to hear. 3 core!!!
