Selling a Ls1 F-body Yank SS4000 converter. The stall has under 50 street miles, dyno time and 3 passes at the track on it. My car made 500/415 unlocked, ran 10.7@125 with a race weight of 3800 pounds. Converter worked good on motor but isn't going to hold nitrous. After talking to Yank they recomend restalling to PAS3400. I'm past my 1 year free restal because of time building car, Yank wants 275 to restall it. So I'm offering this up to give someone a chance to save some money, if it dont sell its going back for restall.

All run time on converter can be seen here.
