I would get an Edelbrock performer 4bbl. intake manifold with a Edelbrock 600 CFM. carb, summit racing has everything you need. --------------------------------------------------------------------------------------------------- Holley 650 double pumper for the win!
I have never seen a cast iron edelbrock intake so I would think not.
A four barrel carb usually adds about 20 hp.
That would be a Rochester 2-barrel are a 4-barrel Quadrajet. You did not say what size. This would not be what they call a FEEDBACK carburetor
go to google or yahoo and do a search for "vacuum line routing edelbrock"..... it should give you alot of pages. choose the one from edelbrock.
around 220hp i would say
with adapters you could but it would probably lack performance and efficiency.
I can't see any reason that it would.
Answer I HAVE A 381 STROKER IN MY TRUCK AND I TRYED A 670 HOLLY AND IT WAS NOT ENOUGH I HAD TO AJUST ON IT ALL THE TIME ,I WENT TO A 750 EDELBROCK AND IT RUNS GREAT.750cfm, vacuum secondaries. also add an additional vacuum canister. you will not have brakes under hard accelleration if you have power brakes. the 383 is notorious for not creating normal vacuum. Answerdefinetely Edelbrock 750 cfm carb If it were me i would get rid of the junk edelbrock carb and get a good 670 cfm holley street avenger carb that's more than enough carb for a sb 383 up to 550 hp
The Edelbrock Performer and Performer RPM would be good choices. Also there are a couple Weiand dual plane intakes that would work well.
With stock manifolds I expect this motor would be around 300HP.
It could be a weak battery or a bad ignition coil.
That would be the electric switch that is screewed into the intake to the left of the thermostat housing.
Yes. Generally you would also want to replace the intake manifold as well, but there are adapters made for this purpose that work fairly well with some loss of efficiency.
Nope. You would still have only one firing pin- but now it would not be in line with EITHER barrel.
a barrel full
(305 displacement x 5250 rpm) divided by 3456 = 463 cfm carburetor 500 cfm x 3456 divided by 305 = 5666 rpm I would say if you are just using the engine for the street, a 500 cfm carburetor is more than enough. Perhaps an edelbrock with an electric choke would work nicely. The carburetor is only supplying the fuel. A longer duration cam, say around 200 degrees at .050 might perk up the engine a little and still let you run vacuum for brakes and automatic transmission. You would just have to read what others have done and look at performance parts companys online and see what people say.
This is really just a prefrence, most run aluminum. From Dart, Edelbrock etc. Depends on what racing you are doing, what cam you have. Intake, Header sizing. Probably the only general information would be some with a 2.02 intake valve diameter and a 1.6 exhaust.
The oem is a Rochester Quadrajet, but you could also use a Holley, Carter or Edelbrock, among others. It would be best to pick a carb that you or someone you know and trust knows how to tune. In the alternative, buy a book on tuning the carb of your choice.
You would often find the barrel organ being played in churches.
In 1990: $23.19 per barrel. (this would equal about $38.35 in 2010).In 1991: $20.20 per barrel. (this would equal about $32.14 in 2010).
With the mods you describe I would suggest you start at about 10 to 12 degrees btdc. you may have to play with it to get it just the way you like it. Hope this helps. Mike
check ur fuel filter and if that's good its time for a tune up.
Look on the carb for a small vacuum source above the throttle body. You would want one that has no vacuum at idle.
