Has anyone ever used the old offenhauser tri power setups. I think they look good and alot cheaper than a Mopar six pack.

I have been eyeing the old CB 750s just to beat around town on.. My 4 carb Honda 750 was as bad as it got for me. And I was doing the same thing. After every round trip.
I'll be honest. I don't anything about them.
I never wanted to because all my memories of them were being with guys that had them and trying to tune them leaving their driveway and trying to tune them when they got to the local hangout. Gawdamn they were annoying. Soured me for life. My 4 carb Honda 750 was as bad as it got for me. And I was doing the same thing. After every round trip.
BTW Stan, you're cool for an old guy!
Part of what used to happen with the older 3x2 setups was they had a solid linkage rod between the two end carbs. Good in theory, in practice, what happened though was that rod would expand and contract enough with a warm vs cold engine and ambient temp changes to move the end carb butterflies a few thousands of an inch, just enough to get air flow and mess up the mixture settings that you had just spent hours getting "just right". Changes in humidity as the day went from dawn to dusk also messed it up.

Seems like some of the carbs had genuine idle circuits in them and others didn't?
Some of those mechanical linkages were better than others, from what I've read. Some were "default movement" in orientation and others were "progressive", which allegedly worked better with smoother transitions into the end carbs opening.

The Offy setup was Stromberg 97, Holley 94, or Rochester 2G carbs with a mechanical linkage. Nothing like the six barrel/six pack OEM Mopar setups.

I'd stay away from it myself. This was 50's tech. Old carbs that you aren't going to get parts for etc. Performance will be most likely dismal at best.
IMHO, the appearance would only look "right" in a nostalgic custom or hot rod. Not a C body.
