500 cfm would be about max. If you can source one a carb from a 4.1 should fit the edelbrock without a problem.
Look for 80 Buick full size cars that was the first year. Not common but they are out there. Some caddys also had the 4.1
I've never seen a Buick 3.8 in a 3rd Gen Monte only the Chevy version, was it a swap in deal or stock? 80 and 81 had a turbo 3.8 as an option.

the monte im building has a factory 90* buick v6 its what came in it so i want to keep that part og. i know its not alot of power but its just a cruiser
ok. First thing's first, the 3.8 NA Buick V6 is a wonderful little A-B engine. Great for cruising and can be built decently well if you're not afraid to spend a little extra dough. For that carb, yeah. 500cfm with stock heads is pushing it but it will work. If can find a Buick 4.1 V6, its the exact same engine, just with a bigger bore if memory serves. They were found in these cars from GM:
Buick
'80 STD-Electra, OPT-LeSabre
'81 STD-Electra, Riviera, OPT-LeSabre, Riviera T Type
'82 STD-Electra, Riviera, OPT-LeSabre, Regal Note: Included in Grand National Package
'83 STD-Electra, Riviera, OPT-LeSabre, Regal
'84 STD-Electra, Riviera, OPT-LeSabre, Regal
Cadillac
'81 OPT-All except Limo
'82 OPT-Seville, Eldorado, DeVille, Fleetwood
(NOTE: badges will say 4.1 for V6, 4100 for Cad V8)
Oldsmobile
'81 STD-98,Toronado
'82 STD-98,Toronado
'83 STD-98,Toronado
'84 STD-Toronado
Pontiac
'82 OPT-Bonneville, Grand Prix
You can get a 4 barrel carb and intake off of these that will drop right in, with NO modification whatsoever.
For this engine, all the normal stuff will work. Head porting/new heads (I believe the GN Turbo heads are the same but flow better), switching from dished to shallow dish/flattop pistons (depending on application), regular ignition upgrades (plugs, wires, coil for the HEI dist.), and exhaust. If you get a decent cam and exhaust, you can get it to idle like a V8. 😀
Or, you can go turbo with a drawthrough system. Won't be able to run much higher than 6 or 7 PSI safely with a stock engine, but it'd be pretty unique. '79 Monte with a drawtrhough Buick V6.
These Buick engines hate hate HATE being run low on oil or with low oil pressure. Don't even chance it, ask me how I know. 🙄
Lastly, I don't know the setup for the instrument panel on late 70s montes, get yourself a good set of gauges too. Oil pressure, temp, and volts for starters.
Hope this helps.

Don't use any brand but the stock rochester / quadrajet w the v6 or it runs rich and at first it seems good but over time it's not good. You don't even need 500 cfm w the v6 that's the highest you can go w/o problems unless it's modded / bored out and all that. Isn't the stock v6 just 380 cfm or so? Find a regal / riviera / olds and take 1 off. If it doesn't match up you just need an adaptor plate which you could get off jegs / summit easily...
Gotta agree here. The Quadrajet is a variable CFM design and will limit itself too what your engine requires.
what about runnin a webber, the only reason im asking for other ideas is cause im having a hell of a time finding a stock carb
