Hey guys, I'm doing a mild build on my 1987 Chrysler fifth avenue 318(big cam, 4 barrel swap, headers, and a limited slip 8 1/4). I know that they either came with the a904 or a727 and I'm not sure which I have or how to tell for certain, I know the 904 isn't necessarily known for its strength so if I do have it will I be okay to use it with a rebuild or should I swap out for something stronger
