I want to get a new radiator for my 67. I called Griffin and they asked me to measure my radiator to determine which one I needed. I don't have the radiator that came in the car. The car has no radiator to measure. So they told me to measure the distance between the radiator mounting holes. There are several holes in the core support. Can someone tell me how to determine which holes in the core support are for the radiator? I looked in the Classis Camaro catalog and they say their core support will work with either the big or small block radiator.

Will the stock core work for either radiator? Which one should I get?

Thanks for any help.

The stock core will work for either radiator. Your car could have come with either a 21'' or 23'' radiator.Those dimensions refer to the core size.The 21'' was standard on small blocks and 6 bangers.The 23'' was available with the heavy duty cooling system which was usually included when you got A/C.The 23'' radiator was also standard for the bigblock. Just make sure you have the right shroud for your application.There are three different shroud available for your year.Small block (no A/C) - 21''. Small block with A/C - 23''. Big Block - 23''. I have a Griffin 23'' radiator in front of my small block.I chose the model with the 1 1/4'' cores.I have no cooling issue's with my car!They are pricey,but I assure you they are worth every penny.The quality and fit is out standing and it is 100% MADE IN TH USA.Good luck.

HI MATT . I don,t know where you are in ma . but if my brain still is ok i think it should be 21or 23 inch core . i believe the 23 was for the 8 cyl H/D cooling. IF your any where near MEDFORD LEXINGTON give RODGER,S RADIATOR A CALL . That,s where i got my radiator and gas tank nice people good price. i have a 70 ss with a 3 tube ac job no problems with cooling at all but its not alum it,s a brass copper oem type MODINE and i bought them both abot 6 yrs ago. hope this helps.:) AL:EX

Both sizes the guys gave you will work. You did not state what your app is, BB or SB? Or hp you will be running? Are you going to run stock fan/shroud set up? Or are you looking to go elec set up? My 69 had factory a/c but only had a 21" radiator. I am now currently running a BB radiator and dual elec fans (Entropy).

I am using a 400 small block that should make around 500 Hp. I want to use an electric setup. I plan to put A/C in the car at a later date. I haven't yet chosen a radiator or electric fan setup.

Thanks for the help.

Instead of Griffith Radiators,I would recomment the Aluminum Flex a lite with electric fan and shroud attached. That is what I replaced the Factory Harrison 3 Row Radiator with in my 68 Camaro Coupe, I live in Las Vegas, NV where it get's very very HOT in the summer months. Also the Flex a lite has a thermostatic control, that you can set the electric fan to come on, and also will shut down by itself when it reachs the temp you have set. Solved my Heating problems here in Vegas, and especially when cruisin in bumper to bumper traffic on the World Famous Las Vegas Strip.........Contact Flex a lite. com customer service and they can tell you the Radiator(s) they recommend for your Camaro, they know which one it is, and do not ask for you to measure anything..........
Bye the way, I have the Harrison 3 Row Radiator in excellent condition along with the Factory Shroud For Sale............... Good Luck..........................

Custom aluminum shroud on it's way
You deleted the picture of your shroudless setup. Out of curiosity, did you run the car on the street under various conditions etablishing your evaluation of great operation without it being fully set up?

A properly set up stock GM cooling system operates efficiently. Many start throwing aftermarket components at an issue without diagnosing their problem. Unless they want aftermarket parts for a particular look other than stock.

Figured I would re post with shroud because it dose look unfinished . Funny when I posted it I thought I should get a shroud. Although in hot humid weather I was cruising the strip at about 5mph for a period of 15 min it did not creep over 190. During steady driving it never runs over 175. my builder told me the heads are good breathers and get rid of allot of heat.
