Another vouch for the Tri-Shield Performance converter. Either through Cliff or direct from TSP.
I had a B&M holeshot 2400 and replaced it with the TSP 9”. It drove about 90% as positively as that too tight B&M but once you stick the throttle the thing comes to life.
I don’t have the car back yet, but through another TSP converter in the 4l80 I had built. Billet face, triple Kevlar discs for WOT lock up etc.
