need balancer/pulley advice..

[oc192]

Hello, I have attached a pic of my current balancer. Is this a stock unit and if so, what are the dimensions? If I deviate from the current dimensions, what sort if issues could I run into? I would also like to get some pulleys from 440 source but they say they are underdrive. Will this cause overheating/charging issues? Also, what would be a good balancer to get? I have a 440HP motor with forged crank.

Thanks,
Don

I went to my Dodge dealer and ordered the Mopar balancer.

If you want to investigate this with your dealer the part number is: P5249694

Also available from YearOne and Summit.

Your balancer does appear to be for an internally balanced forged crank.

I am using this on my forged crank 440

What is wrong with the pulleys you have now?

Be aware of the bolt pattern on your crank pulley before purchasing a new balancer - their not all the same. Also read the fine print if purchasing a new pulley because some are only rated to a certain RPM, after that it's your liability if the stacked pulleys separate. If the max RPM is not stated on the website or in the catalogue call in person to find out. This is not an issue with machined pulleys by popular manufacturers. It would be better to stay with OE sized pulleys as a lot of engineering went into the final conclusion of sizing. If you want to lessen the load caused by accessories "upsize" the alternator and power steering pump pulleys - they're cheap and readily available but I'd definitely leave the ratio between the crank and water pump pulley as is.
