I have a 30' Chris Cat and am needing a carb for my port engine. The carb that is on there now is to small of cfm. I am needing a weber casting number 9776s. I may also consider buying 2 other matching carbs and just replacing them both. Who can help me out or what's out there? Thanks in advance

I will look at the numbers on the one I have. I just bought a new one yesterday and the old one would be fine with a kit. It is on a 1997 7.4
It will be later today after work. Oh, and I am in Ark City and work in Wichita.

The 454 and 502 carbs are different. The air passage drilling in the housings are different. That's the problem I've ran into. I have a 454 carb now

I have a whole slew of weber and carter carbs and the weber for a 7.4 is prob peanut port tune also
i would be curious what jet and rod sizes the 502 unit has.

I have a pair that I've had re-built, and been on the shelf for the last 8(?) years.I know one was from a 1995 454 Mag. Not sure what year the other one is.
I'll get numbers & pics asap.

One is - 9779s
The other looks like the same number, but not positive.
