Where are all the running hot posts?

So.....

It's a 3 row 26", and there is a shroud.

Drove it almost all day without AC, and never got above 170.
In fact, it never moved unless I was in someplace long enough for it to cool down.

Next day I tried the AC and within the time it took to cool down, it was 185-190.

I'm researching fast idle solenoids and the info is kinda scarce.
WAY more info on idle stop.
Interestingly it looks like there's an older design unit that can be used for both.
Edelbrock sells it for...wait for it...$200!
If you shop, you can find it new for as low as $35!

I've got a factory one and BBx carb mount from a 5th Ave, but it's shot.
At least I have a mount. Looks like there's an added lever on the throttle to accommodate it.
Might need to be fabbed.
Getting the old solenoid out of the mount looks "interesting".

Maybe I'll cough up the $35 and experiment.

I also noticed a 5th Ave at my local U-pull.
Maybe I'll go have a look at that.
