L78 Nova fan noise.

The 'howl' as you call it is standard equipment for these fans...they all do it.

Back in the day the noise was the reason a lot guys went with a flex-a-lite unit...the noise got to them.

No need to worry...if folks ask about the noise, just tell them you have a mini-blower installed and don't open the hood

Thanks in advance

As noted, the space is the issue...the first year of the big block Nova [1968] used the short water pump with a clutch and 5 blade fan...that was the only year for that setup.

And despite what the 'repop catalog' guys show on their websites, there was never a spacer between the fan and water pump on the 69-70 cars. As for the lack of noise...?? hard to answer that one...maybe post a photo of the fan blade so we can see what you got.
