Recommend a Carb

[charger1970]

I have a 383 charger with a 454 lift cam with a 268 deg duration. Can anyone recommend a carb for this engine? Someone suggested a Holley 670 Advenger Carb. Does anyone know if this carb would be any good?

Excellent choice!!!

Currently I am running a 770 Street Avenger and I love it. I am running a built 383 with a Comp Cams XE268H cam with i believe around .470 to .480 lift. The car idles excellently and very little tuning was needed. Throttle reponse is also top notch. It was either this, a 750 Street Demon, or a built TQ. The carb comeswith an easy to adjust vacum secondary, there are 2 large ports for vacum assisted accesories and one small port for tuning plus a vacum advance. The fuel bowl have see though sight plugs and they work right out or the box. The electric choke is a help and it is easy to hook up. I thought about the 670, but I'll be going to an RPM intake eventually which will help. Currently running the performer which is probably limiting my potential.

Agreed. The 670 would be excellent for a stock app. The choice made by 71383bee for his warmed up engine is good. The future changes he has in mind will bennifit from the extra cfm. With the larger Extreme cam and future intake in mind, it will only help.
670 is plenty of cfm. Should feed the 383 fine.
600 cfm can feed 300 hp.

Thanks Rumblefish! I also plan on 1.6 roller rockers and maybe edelbrock heads eventually. Not too sure though the 906's I'm using now are pretty ported and polished.

By the way if it was not for the steering column I bought from you my bee would probably still not beroad ready!

is fuel mileage a consideration? If not the Berri would be the best and EZiest choice but if performance with reasonable mpg is a consideration - consider the TQ.

[rumblefish360]

1.6 & edel. heads. Sounds great!
I have to give back the credit on the steering column. Not I.

Mister Fiberglass, the champion of T-Q's!
And with good reason!

[71383bee]

I could have sworn that was you. I ordered a floor shifted 71-74 B Body steering column out of a GTX I believe late last year form Rumblefish Performance. Is that you or am I thinking of someone else? I got it from a post on Mopar Collectors Guide.

[rumblefish360]

That would be some one else. Rumblefish Is in upstate NY I believe.
I'm with a 360 at the end. I would have signed on as just rumblefish, but when I first started getting set up on the computer, there were a ton of rumblefish's. So I just took the current engine cid and added it on. So it stuck on everything I signed on to.
"Rumblefish" is here from time to time.
Rumblefish360 is here all the time. Ok, ok, to much.

[71383bee]

Ahh ok then...well you're all right too! I'll buy you a beer too if I ever run into you.

charger1970 I would go with the 670 Holley if your sticking close to stock or staying with the setup you have. If you plan on doing more getting a 770 now wont kill your car. You may have to tune it more by downsizing jets maybe and adjusting the floats, but it's no more than what everyone does with holleys/demons.
