8 3/4 Question

I run a e body width on a duster which is much more forgiving and nobody has ever noticed anything LOL
My advice is to run from this rear end fast! Someone didn't put ladder bars on it and take it out for Sunday drives to church. Unless they went to the Church of drag racing and beat the crap out of it with ladder bars?
My question to get out of the gate here is what motor is this going behind now and is there a potential for a bigger motor? Like if you have a slant 6 in there this is all a joke, but if you have plans for a stroker motor or something ??
