Actually, not on this engine. I have found a stash of brand new, NOS original Zenith carbs specifically for 270 and 302. I'll install that and run it as is while I rebuild and hop up the 302. I'll be doing that to the 302 though. It's too easy of a mod NOT to do it during a rebuild. Looking forward to getting the carb on the 270 and dialed in. Itll certainly run much better.
