Chastise me if you will, but I absolutely hate a carburetor. Especially a 70 ish year old one. Rebuilding on one of these is still "polishing a turd" to me. That's my opinion. On another note, I tried FiTech on my old 235 and had the worst experience with it. It Ran right for less than 500 miles and then myself and FiTech never could make it run right again. I eventually canned it and put on a 350 cfm Holley 2 barrel straight from the box. Ran good, but still a finiky carbureted vehicle. I now enjoy my injected 4.8 LS motor. My truck is a my daily driver and I want trouble free starting and driving year round. I have heard positive feed back about the Holley sniper systems though. If my 235 was still in my truck I would certainly try again with a Holley unit.
