hi when i went to bolt up the repo hemi pulley on the new crate motor the pattern would not line up i grabed a 440 one same thing does anyone know if the bolt pattern on the new crates balancers are different or is this one messed

The original balancer and pulley had one offset hole, most of the new balancers have equally spaced holes.

I bought a new set of pulleys that were suppose to be for the new crate motor but wouldn't line up. They were used, someone had started elongating new holes.

Anyhow we were able to end up using the 440 one. I know the Hemi pulleys weren't cheap.

If the rest line up just elongate the one hole.

well i bought another one from mopar performance an the holes arent drilled the same as the one i got 2 years ago but there definately made by the same company bad news it doesent line up either i wish mopar would pull up there socks this crate is the 2008 version and im not sure if the old damper was drilled different my 440 pulley would not bolt up what a mess thanks for your input

Is the new Hemi balancer on the crate motors set up for the old (68-71) thick balancer pulleys or it it set up for the BB pulleys?

Did you rotate the pulley untill the holes line up??

oh about 100 times, the closest is one hole out buy apoxx 1/2 a diameter of the hole I just hate to bubble gum a new part theres definatly some problems with the damper I will get a new one and see, at least the dealer here cares

The reason I asked about the pulleys was because of the alternator pulley alignment. If you use the original style crank and water pump pulleys, you will also need to use the correct original Hemi alternator pulley, assuming the the new pulley is the same as the original, with the exception of the mounting holes. If the new balancer is made for the BB crank pulley depth, you will be able to use the standard alternator pulley and the BB water pump pulley.

My crate motor has the thin balancer. I order alum pulleys from mancini. The crank pulley needed a .37" spacer to achieve alignment. I painted the pulleys black, and I think I had to elongate one hole. I think the pulleys were around $150.

THis was about 4 years ago, but everything is still fine.
hope this helps.

It's simple. The crate motor uses a balancer with the depth dimension like a 440. As for the bolt pattern, older balancers had one bolt hole positioned different than the newer balancers. Some of the stock pulleys had one hole elongated from the factory so they would fit on either balancer. Other pulleys didn't have the elongation, and only fit one balancer. So as has been done for years, rotate the pulley till it lines up with all the holes, and if it doesn't line up with one, elongate it a little, and it will be just like the factory pulleys that came that way.
