Best carb for stock 454

[SmallsTX]

I'm looking around for a new carb. I have a 80 c35 7.4l. At the moment I have a 700cfm quadra junk ( I know it's to small). I'm thinking a holly 800 or 850 cfm. What do y'all think?

I think the correct Quadrajet.

A bigger Holley! Use the Q-Junk for a paperweight!

The best carb(s) for a BBC are two Impco 425s....

propane btw... just had to say.

Definitely keep your engine clean running propane.

I would agree if its unmolested.

Since yours isn’t an 800 CFM Quadrajet, that’s what I would suggest. If there’s a crummy 454 motorhome being parted out on Craigslist or in the junkyard, there you go. Holley’s fine, but I like the old Rochester.
