PRW SFI BAlancer P/N 2431841 which balance weight.

[mopar65]

Help. I just got my new PRW balancer in and ready to install it on my magnum 360 engine. The snag I have ran into is the balancer comes with 3 diffrent weights. Of course the way my luck goes, the instructions don't say crap about which weight is used on which engine. There is a large weight,a middle sized weight and a small weight. THE middle weight was already installed when I opened the box. The only weight I can see any numbers on is the large weight. Which is GW012-1. So I am unsure which weight goes with what engine. Any body else run into this problem?

Hey thank you very much for the help. Looks like I need to learn how to read better. Lol I didn't know that info was in there catalog. But it looks like it has the magnum weight on it now. So i should be ready to install it in the morning.

I just got the same converter for my magnum build, thanks for the info! What key did you use for the crank? I bought a short block and don't think it will come with the crank key... is there a specific PN or would any that I can make fit do the job? Worst case scenario I can get one from the junkyard I guess...

As far as I know mine just has the factory magnum key
