FTI TC Anyone run one?

I've got an FTI 4000 hard hit 9.5" (SRC80828) ordered from Summit, built a couple days later and shipped direct from FTI.....paint barely cured!.......It's sitting in the staging lane (along with other engine goodies) Plan over the winter is to pull the 727, install the converter with new pump bushing and seal (and make a few small changes on the engine) I've read on many other sites, they have a good reputation and are heavily into racing. The converter looks like a converter so that's a good start! The welding is top notch.....we shall see. By the way, I have been running a Turbo Action 10" tight, advertised to flash 3500.....and it does. But I want more so......

I run one. 9.5" 3400-3600 stall. Does pretty good in my street dart sport 360. Had a cheap 10" Dacco I recall. No comparison FTI is much better! When I got mine took a high risk and bought it slightly used from a guy who parted out his swinger after it suffered a total loss accident. Been fine now for 5 years.
Awesome reviews, guys! How were the street manners, and with what gears?
