BS. I'll post a picture of exactly how little of the 26" radiator is "covered" by the 22" radiator shroud. It has little to no effect on the cooling abilities of the 26" radiator.
And, that's only if the fan isn't running. If the fan shroud covers the whole radiator, the fan pulls air across the whole radiator. That's why the shroud is there.
No, I am not suggesting the OP overdrive the fan. I'm suggesting he find out if he's underdriving the fan, and whether or not he has the correct water pump for the pulley set up he has. If he has a mismatch of stock pulleys, he may not have the drive ratio he's supposed to.
I have no idea if a 26" radiator was available stock in '68, I don't believe they were. That said, yes, a stock 26" radiator will fit in his '68. 26" radiators were available in all of the later A/C cars, the radiator support is the same except for the opening. And the opening isn't that different.
Hanging a pusher fan out if front just slows airflow the rest of the time. A properly tuned mechanical fan system should work just fine for the OP. If you want an electric fan, the mechanical should be dropped entirely and replaced with an electric to handle all the cooling duties. Running both is just inefficient.
That is a great looking car! :thumbsup: I love notch's!
Yes, I would suggest confirming your temp gauge readings are accurate, the little aftermarket gauges can be misleading. My autometer temp gauge reads like 10°F high at 200°. Pictures of the rest of the radiator and shroud set up will help, it doesn't look like you have a stock shroud on there. Also, a picture showing where the fan sits in the shroud would be helpful, as they have to be in the right spot too.
He doesn't need to overdrive the fan. He just needs to make sure he has the right pulley ratio.
