I had three on a 261 for a while that ran fine. I guess I just didn't know they were hard to tune. I only took them off because I found a '54 Corvette 3 side draft setup. I've run 2 on other engines. I had a lot more trouble with 3 and 4 97s. After doing that for years I found a 4bbl manifold for the Flathead in my '51 Ford woody. It was the sweetest running flathead I ever owned.
