(1) new in the box Ultimate Converter Concepts 10" Powerglide nitrous converter with turbo splines. This converter is set-up for a BBF with nitrous with approx. 1500 horsepower. I would think that if this converter is too tight for your combo it could be loosened up some. I believe this converter sells for approx. $1200.00 new. I will sell for $700.00 Contact Kevin Rowe at 812-969-3119 between 5:00pm - 10:00pm EST. I am located in Southern Indiana Thanks!!!!!!!
