Magnum converter weights

OK im hoping one of you guys can give me an answer here. I had to pull out my LA engine and installing my Magnum. I know the magnum uses 14 in ozs of weight vs the stock LA at 19 in-ozs. There used to be a kit for the Magnum (P5249843), but i can not find any trace of that kit online. I have the paperwork from that Kit, but not the weights so im wondering if anyone can tell me the actual weight of the 2 blocks in the kit?


HELP!
