425 Pulleys onto a 500

[Danillac]

Hello, I have a 1976 500 in a 1986 Chevy dually. I have a full set of 425 pulleys I would like to put on the engine. I know every thing will bolt right on. My question is this. On the crank pulley, do I need to use the hub from the 425. Also, this is just dumb, does the 425 have a balancer? I ask this, because it has been a while since I pulled the pieces. I have also moved, and have not yet found a balancer from this 425. If it does have a balancer, do I use it, or the one from the 500. Any help is greatly appreciated. Oh, beings we are on the subject of 425 to 500 parts. Is there any clearance problems with oil pans? I would like to put a 425 pan and pick up on my 500, but I want to make sure the rotating assembly will clear the pan. Thanks again, Danny in Missouri

i recently pulled a 425 setup for mine and there was no balancer.i reused my original balancer and the crank pulley bolted right up to the 472 hub.it makes a clean setup if your not runing air condition.
