Some help sorting it out

I didn't see one listed for 66-68 , only 68-71 ???

This is the one I bought from Megaparts:

That is the 69-71 , stared being used sometime in 68 I believe , you need the deeper of the 2 hemi crank pullies.

If you have the right lower pulley the grooves between the 2 pulleys should not be more than a groove width apart with your dampner on as far as it was in that picture.

After doing more reading it seems that any single groove big block pulley is the same for the 66-68 Hemi also. I have plenty of those laying around and will give it a shot.

Link please because that can't be right , the hub is also thicker on an ORIGINAL Hemi balancer. , if one runs a thin balancer on the Hemi then stock B/RB wedge pullys can be used , this not the case with the Hemi.

Not so None of the stock 383/440 water pump pulley, NONE of them are the same as the 1966 to 1971 street Hemi water pump pulleys Many people, me included, have tried to use a stock 383 single groove water pump pulley with a 440 dampener and a 383/440 bottom single groove pulleys, they are absoulutely not comapatable on a 426 street Hemi motor

Web Site Techs, Why is this post making my computer show 4 different links to this web site, on this post only
Please fix it!

OK, I read the Bouchillon site above and that is what is said, unless I am reading it wrong!?! It is pretty hard to read, so it just might be me again...

Cab , unless the snout of the hemi crank is different in length how is that not possible considering the hemi uses the same timing cover and waterpump housing ?

Interesting learning going on here. I will stay tuned for my future project and learn as well.

So I put the puller on the dampner and moved it back to where the alternator lines up with the crank pulley and the aftermarket Hemi water pump pulley is not even close. It looks like the pulley I need would just about hit the water pump bolts like on a 383/440. I do have another supposed Hemi crank pulley that is smaller in diameter and shorter than the one I have on the car which I was told was the right pulley. So, what is the diameter and height of the correct Super Stock Hemi crank pulley and water pump pulley? I will ask over at Class Racer and see what they say.

On my Hemi the water pump pulley is so far back it covers the water pump bolts...i.e. they fit inside it.

What I remember on the 426 street Hemi pulleys is that the 1966 to 1968, maybe even some early 1969 cars had the first version which Mopar changed in 1969 to 1971 cars to the later pulleys I can't remember what the exact differences where now The 1964/1965 Race Hemi used a thin balancer like the 361/426W motors used with the straight timing tab timing covers. I think the later(1969/1971 Street Hemi) ones had a smaller diameter crank pulley As far as my statement on the water pump pulley I'm probally wrong on that now that I think about some of the standard steering (1962 to 1971) B/RB motors I have that there water pump pulleys might have work one or the other street Hemi motors

That is what I have been seeing, but I have not found a real good picture of the area, I need to do some more searching. I did find this pic of Max Hurley's Hemi Dart.

I have March alum pulleys and the water pump uses these pan head bolts for clearance. Since my pulleys are thicker than steel ones, they may need more space. But the point is the pulley is as far back as it can get.

Thanks, that is what I have seeing also.

Agreed on using pan head bolts (there are many varieties). they've saved my a$$ in a few situations

If your going to use a non stock bolt without the built in thread sealer inserts on the water pumps make sure and use a thread sealer on the bolts to prevent coolant loss around the threads

Good reminder, AF leaks are the cats ass

That looks like a B/RB non A/C waterpump pulley , the matching crank pulley for that on a stock hemi balancer would be very shallow.
