The converter I bought is for external balance small blocks. Its a boss hog 2800 stall for a 904 the amount weight for externally balanced 340 and 360 are different... can not use a externally balanced converter for a 360 on a externally balanced 340....need to knock weights off converter and get B&M weighted flexplate for externally balanced 340.
