The russell kit I got from Tony D at newedgeperformance.com, worked just fine. However, I was using a complete used set-up off a wrecked SVT from focussalvage. I wonder if the Ford kit is a bit different. I may still have my receipt from Tony, or maybe he will remember what I bought, It has been two years ago, so I really don't remember. I"ll see if I can figure out what I put on there. I know they are stainless, and I think they were russell.
Speed is only a matter of money; how fast do you want to go?
