looking for a new radiator

I currently have a 3 core rad in my Chevelle with a mechanical fan/454 500hp. Should I go Aluminum or OEM?

Re: looking for a new radiator

Timing is perfect. Look up the threads on.Alumatech. Think Don may be back in business. He had some NOS units he was selling at a discount. Might want to see if he has any remaining.

Re: looking for a new radiator

I bought a OG style from Ausley's. 4 row. still happy with it after 2 years. I bought an aluminum one from Griffin and had to cut a lot out of the core support to make it fit and then it leaked anyway. Alumitech has got a good reputation from what I heard, but don't know if it's an exact fit.

I bought one of Don's Rads/Alumitech 2 Row 1.5" Tubes and it was a Direct Fit with no mods required

Great Unit and very/very happy with it

If Don does not have one for you then there is always DeWitts

Aluminum is lighter and disburses heat better

NOTE more than 2 Rows of Tubes in a Rad does not mean it will necessary cool the coolant down better/faster

I did the aluminum one. I just think it looks cool and price for a Chinese aluminum one from eBay was cheaper than a stock style one. It's been fine never gets hot or leaks.

Re: looking for a new radiator

I was looking at that. How well does it cool in the summer and traffic?

Re: looking for a new radiator

Look up Scott Wheaton's cooling info here. It has all you need to know about keeping that BB cool with factory components (small blocks too). And here is but one of them: Temp for a BBC with stock cooling system?? Don't throw out your Harrison radiators. I save tanks and have them re-cored. My lowly 396/375 67 Chevelle with a three row and shrouded fixed stock fan holds at 180 when I bought it. I'll toss on a clutch fan because I prefer them.


By the way, there is no such thing as a 2,3, or 4 core radiator unless you are stacking your radiators. Radiators have rows. The core is the unit between the tanks.

Re: looking for a new radiator

Mine was leaking a little and I had to pull it out as the PO didn't put any rubber holders under it, so it wandered about, and I wasn't sure what I wanted to do for a new one as there are so many options. So, I figured I would experiment a little and try something.

I bought this one after a little research (part number 433322):

Advance Auto Parts - Carquest radiator

It has plastic tanks, one wide row aluminum core. Keeps my 454 nice and cool at 180*-185* with a 180* thermostat.

It's listed for $109.99 with free shipping, and then I used a $40 off $100 coupon and got it delivered to my door for a total of $69.99. I figured for $70 I would give it a shot, direct bolt in, and it's been great so far.

If it gives me a hard time, I'll swap it out. If not, well, then I'm ahead.

Thank you! I hear muffler bearings every time someone says it.
