1975 Plymouth duster rear end swap

hello, I recently just purchased a 1975 Plymouth duster with a 318 and 727 Transmission. I want to modify the engine and get anywhere between 350-375 horsepower. I am leaning on a daily driver but I definitely want to take it to the drag strip once in a month, not all the time.My question is that will a 8 1/4” rear end be okay for this application? It is very hard to find a 8 3/4” rear end. Thanks.
