going to get a new convertor for my new setup and the one I have is a ptc 9.5 I think round 3800-4200 stall set up for a street strip car with a 904 and a 340 combo, was built for my 340 combo and worked great on street and strip, car ran 11.40 best in a full weight duster, wondering if any one knows what it would be worth or if I would be better off to send it back and rework it for new combo, thanks
