Need everyone's oppinion

the 8-3/4 will be fine...im surprised that the 7-1/4 actually stood up to burnouts from the 318...didnt know it could take that much of a beating....an 8-3/4 will be good for you for a long time (mind you the amount of money it costs to build and 8-3/4 its rather tempting to build the dana and be done with it)
