get a universal fuel pump from any auto parts store you want to run between 4-7 pounds of pressure
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.
That would be the electric switch that is screewed into the intake to the left of the thermostat housing.
