Carb replacement 63 Impala 409 2x4

[FAZ]

Looking for some feedback on carburetor replacement, not an area of expertise for me. My 63 409 has dual Carter Competition Series 625 CFM. I am not sure what if any engine modifications have been made, What I know is that the intake is stock and has Crane Rocker arms (roller).No performance issue’s main goal was to clean things up. Learning the carbs are not original I thought I would replace them with a couple Edlebrock carbs. My concern is oversizing and am looking Edlebrock AVS 500 or 600CFM.

I had two 1403 or 5 Edelbrocks 500 cfm on my 409/425 hp ran great no issues. I have a single 500 cfm on my 400 hp runs great also.

Keep the Carters and rebuild them when needed?

There are several very competent rebuilders on this site, and a few out there who have good reputations also. I'm just saying if it were mine, I'd probably consider one of the rebuilders here, or somebody like SMI. The AVS2s have a pretty good rep, but the Carters are sometimes preferred by people who know a lot more than I do.

No performance issues but you want to clean things up. What needs cleaned up specifically?

I have the original carbs on a couple of engines and edelbrock 1405/600 cfm on my latest one i prefer the original carbs but i am still working on the jetting on the edelbrock ones. Those carters should work just fine are they running ok now

They do and are running good. Just considering if I should rebuild or replace while I have them off.

I have taken the time to freshen up the paint on the chassis, engine and under the hood and finding that the previous owner rebuilder weren't very gracious with things and the carbs could use some work to bring back to looking original.

My Brothers carb before and after. I had it vapor blasted and used quality rebuild kit. I also went online and bought CERAKOTE ceramic paint for ferrous metal parts

Looks great, where did you purchase the rebuild kit and have it vapor blasted?

I've been struggling to find a place near Myrtle Beach area for a place that does glass beading I imagine will have the same success with vapor blasting. Thanks for the info.
