OK,I need a reliable set of cylinders NOT STOCK like .10 or .20 over(nothing above .40) with either an agressive dune port or a drag port,with pistons don't need a head,i'll trade either my cylinders bores .100 over with wiseco pistons rings in them got a dune port by speed tech and the cylinders are polished,or 2 JL 10" subs not in a box beat SUPER hard for 10's,if you have a set of cylinders i really want i may give you all my stuff for em.
