Technical 289 pulley

Hey guys. Looking to see if anyone can tell me if there is a difference in the depth of the lower crank pulley on a 289? I currently have a 3 groove and looking to go to a single groove pulley. Want to make sure I get the right pulley. thanks in advance

 

What year 289, and what car did it come from?

Ford managed to have quite a few front drive setups on the SBF. My last best count was 23.

 

I was told it’s for a 1965 fairlane. The engine was already in the car when I got it. So I’m just going off what the previous owner told me.

 

The primary sheave in the system is the closest one to the block.

If that is indeed the year of the engine, you should be able to swap out the triple for a single.

Worst case, find someone with a lathe, and have them part the unneeded metal from the triple.

That could be done in about 2-minutes.

 

I was thinking about putting it on the lathe at work and get rid of what I don’t need. Just like you mentioned. I may just do that.

 

Is it a three-bolt or four -bolt holding it on pulley? The three-bolt crank damper was 62 to 69/70, the four-bolt was all later versions in car/truck applications. The three-bolt damper survived in marine applications at least into the late-80s, but used weird pulleys. Some slight machining was needed to use automotive-type pulleys.

In my experience, the '65-70 Mustang/Falcon/Fairlane mostly all used the same front dress, the big cars and all the later models generated most of the variations.

 

I'm putting a 302 from an '83 van in my '54 Ranch Wagon. The lower 3 groove pulley was just touching the radiator. I didn't need the outer groove but I couldn't find a 2 groove pulley. So a buddy chucked the 3 groove pulley in his lathe and solved the problem for me.

 

It’s a 3 bolt pulley. Looks like there is a few options for how deep the pulleys is. I may Just machine down what I have.

 

Yeah, I would do that.

As I have mentioned, Ford had a bunch of variants.

 

Thanks for the help guys. Went ahead and machine down the pulley at work.

 

Looks good!

 

Good move. I like the look of a cleaned up "de sheaved" original. I've done it a couple of times.
I usually have had to make a spacer to get it to align with the alt, but I like doing things the hard way.
