Running an LS or Gen-V LT swap in front of a Powerglide, TH350, or TH400 transmission?  This is the right converter for you!  Our 258mm option will provide you with a variety of stall speeds to choose from.  Our CNC-machined billet steel front cover features a variety of bolt pattern options to suit virtually any LS or LT flexplate out there.  An LS-length pilot eliminates the necessity for any pilot extension sleeve.  Heavy duty TIG welded fins & full furnace brazing ensure the strongest possible converter possible!
