Grandfather's 68 SS Camaro.

Fan is an aftermarket flex fan. Moves a lot of air, but must howl like the devil above about 3,000 rpm.
In your second pic, 4th and 5th rows down under the upper hose neck, there are letters stamped in the tank. Looks like there are some on the other side too, but a little too dirty to make out in the pic.

I wonder if that's playing into the overheating issues that have plagued this car for 20 years. The shroud looks kinda funky too


I see 1969s had a 7 blade fan but the blades look much bigger and more curved than whatever the heck is on the car. I might snag one of those for it. I see they're reproduced and, well, date coded NOS stuff isn't exactly required for this car.

Good eye! Stamped I L so it very well could be the original radiator for the car. That fan will be replaced with an OE style. I don't know what brand is on it but I've heard enough stories about the old Flex-A-Lite fans breaking apart that I simply don't trust flex fans.

Unfortunately, I might be blind but I see no numbers on the fan shroud.

Somehow, over the past couple years, I've managed to acquire 4-5, 7 blade fans and only need 3. I'll see if I can find them all and figure out one you can have. They do require the thermostat/viscous clutch and most of them have one, but may need replacing.

Need to update- Left side tank is I L. Right side is X I which doesn't show up on the CRG list. So if I understand this right (probably not) it was recored at some point and in order to make it work with the TH400 they swapped the right side tank to something else? If that's a thing that can be done, I really don't know. Unless Harrison/GM used the I L coded tanks on other radiators besides Camaros.

[Too Many Projects]

I find the IL tanks on Chevelles too but the X code tank may have come from a full size car and yes, these tanks are very interchangeable, as long as the core is the correct width for the tank.


The fan, if it is too small a diameter to fill the shroud, it won't be effective and in the couple pics we see, it has been noted that it isn't far enough in the shroud. It is mounted directly to the pulley and it should have a 3/4 to 1" spacer behind it.



What is the diameter of the fan shroud opening ? That will determine the fan blade size.
I'm having eye surgery tomorrow, so I'll look thru my fans later this week.

Thanks for the info! It's a 19 or 19.5 inch opening if I measured it right.

The motor is out! It actually wasn't that hard, either. I'd done a good deal of prep work. Of course the driver's header was a pain to work around getting it back in is gonna suuuuuck, but other wise, not too bad. Still took my buddy and I until after 2 AM to get it done, having started at 6 PM. Nothing got broken, no (more, I did saw off a heater hose a while back because it annoyed me lol) more hoses had to be cut, it was.... bliss, compared to some of the crap cans I'm used to working on.

Couple of things to note: The casting number is 3999289, so as the TRX on the front pad indicates, 2 bolt 454 block

Two- The headers still have a couple of very small traces of white paint on them. My OCD loves white headers, and therefore they will get a coat of VHT before they go back on (I realize having them coated would be better, but since I'm going to have to break in a cam, I think VHT for the first season after the rebuild, then pull the headers for a winter project and send em out)

Three- Can anyone ID the headers? Just for pure curiosity's sake

[Too Many Projects]

Headers look like early Hedman. Hooker always welds the collector flange on, usually with one of the bolt ears facing straight down into the pavement.

The only brand I'm aware of that came white were Appliance and they would need to date back to when the car was new to 6-7 years old and have a square collector flange.
They would stand out in white.

If you left the spark plugs in while removing the engine, I'm surprised you got it out without braking a plug on those headers. Damned tight fit.

When you get a chance, take a picture of the outer side of the passenger side header. That might help identify them.

Both photos are of the passenger side. I have another picture of it here.

@Too Many Projects: We did manage to get it out with the plugs still in. What helped was we had the car on stands and were able to pull the header away and down (but not out) before pulling the engine up.
