Using big block pullies on a 426 Hemi

[Daytona Jim]

I'm rebuilding my 426 Hemi using Molnar crank, Molnar rods and Icon pistons. Since I'm using lighter weight internal components why can't I use a 440 balancer and pullies instead of the heavier and thicker Hemi balancer and pullies?
Thanks for any ideas

Let your engine balancer decide.

If you want it to look stock you can use the Fluiddampr. I think your pulleys might line up with it. I would go with an ATI balancer. (I know it's a hassle because they are often too tight and need to be honed.) One member on here said this one lines up with the wedge pulleys, but it is a 2 ring and ATI told me the 917122E would be better because it's a 3 ring. (There is a different part number if you have a thick aluminum front cover.)

You don't want to use a real Street Hemi balancer anyway because of how the factory balance was done.

Done it a few times. Just watch the alternator stud clearance to head.

My car has an aftermkt dampner on it ( Fluid Dampner I think ) And I have regular B/RB pullies on it
