I want to echo all of the good words spoken about Ultimate Converter in this thread. I run one of their converters in a Ford project of mine and spoke to Lenny this morning about a torque converter for my 512 pig of a street car. He was completely honest and informed me that, for my application, he did not have the ideal core for the job. He also supplied me a workable option as a backup. I ended up going with PTC because they did have the core I needed in stock, but I never would have gotten there without Lenny's honesty. I suppose one could call that a bit of a pyrrhic sales victory, but I am very grateful for the candor.
