needing a new rear end and advice

abodyjoe said
is it a stock 318? planning on putting sticky tires on it and heading to the track? if not i'd leave the 7 1/4 in it.

sorry guys lost my password but its a 318 with 360 heads and a mild cam what the guy told me and no its not a track car just my driver but i do like to squeal my tires and take off at red lights
