Hi guys,

I have a question with regards to the depth of the clutch fan into the radiator shroud. Does anyone have a photo or could someone please measure how much the factory clutch fan blades protrude out of the back of the shroud?

Best regards,
Matt

No pics, but IIRC from my former '69 L71 the blades were not quite half way within the rear edge of the shroud. HTH

I'll snap a few pictures for you. I have a 69 with 427 although I'm not 100% my shroud is original.

That's really helpful, thank you!

If you could snap one from directly above, that would be amazing. This forum has some really excellent members.

The reason that I ask is because 1) My car is currently running dual Spal fans and I want to go back to the clutch fan. 2) I want to space the fan about 1" further forward so that I can run a spreader bar.

As long as you've room to move it further in without the fan interfering with the shroud when the motor mounts flex, that's definitely something worth doing if it better facilitates installing a spreader bar.

1 1/4 inches from the top rear edge of the shroud to the rear of the fan blade. All stock 69 427 L36 with original shroud.

I agree. Not that this car isn't tight, but I think that any C3 could stand to be stiffer in the front end.

Thank you very much CanadaGrant. That is very much appreciated and it also means that my plan should work!
