I have never heard that about 153 fly wheels. All of the listings I have seen have been the same as small blocks and L6s. I am sure that there is a 168 tooth that will match or exceed the weight of the one on the 153. If I can I'll weigh on from a I53. I have a couple around somewhere.

OK, did some reading and it does look like Jeep used a heavier fly wheel when they used the 153. I doubt that it is heavier than the 168 toor wheel used on GM 350s in trucks. Here is a Jeep thread that you may have already seen but may have some helpful information.
