I picked this up used and had it running on a 72 C10 Sbc for a bit but it had a stumble, after trying to troubleshoot it and calls to Fitech it quit running and Fitech wanted me to send it in for inspection. So, I yanked it off and stuck a carb on it. The kit is complete but you’ll need some more hoses and another 02 bung. This was a little over a year and a half ago and I don't remember the exact issue. $400 shipped
