Edelbrock 750cfm 1411 or 600cfm 1406? And will be using a RPM or stealth manifold.Car specs in sig.

 

A Holley.

 

600 is not enough for a 383

 

there will never be a run out of the box carb. tuning is gonna always be required.

 

I know tuning is required for best performance.To make a long story short Im having a problem with the wiring in my car and it wont start.I need my car for work and cant waste any more time messing with the wiring.So Im switching to a carb for now.Will either carb be close enough to letting me just bolting it on and driving?

 

I don't have this straight..
you were running a computer controlled carb on a 383 ???

 

No Im running a holley stealth ram and someting in the wiring is messed up.I dont have the time and its to cold out to be checking all the wires of the ecm.So I want to switch to a carb so I can have a running car(I need it for work).

 

Either Edlebrock carb will work on the engine,
but you'll need another distributor, fuel pump, throttle cable/bracket, etc.... not such a quick swap.
It may be easier to just fix the problem.
what are the symptoms?

 

Yah I know its not that easy but Im running out of time here.The problem is weak spark.I can't get spark at the plugs if I take a spark tester and put at the end of a wire it wont jump the gap.If I take the wire off the cap and hook up the tester to the cap it will jump the gap but not with the wires hooked up.I changed the cap,rotor,plugs,ignition module,coil,wires,pick up coil,battery,ecm even got another distributor from the scrap yard and still the same thing.I checked all the wires going to the distributor for grounds and their getting the right voltages.There is nothing left to check that I can think of or find in any books.Also I all ready have most of the parts for the swap just need the carb and manifold.

 

The best carb out of the box is gonna be a Demon. Some tunning may be possible with all carbs but I've had guys say they had to do no tuning to the Demon carbs after bolting on.

 

I run a Jet Performance modified Quadrajet on my 355 and it ran great out of the box, but it wasn't specifically an "out of the box" carb either - I gave them all my engine specs (Cam, compression ratio, ignition, type of intake, headers etc.) and they set it up for me. Never had a Q-jet that responsive.

Edelbrock. They took all the fun out of tuning! My 800 cfm was dead on. After trying all sorts of tuning, my brother went back to the stock caliberation on his 750 cfm Performer. Nice carbs. I can't say I've had experience with any others though.

Thanks for the reply's I really want to go with the edelbrock because I dont want to drop alot of coin and most people say the engine will run with the edelbrock out of the box.Im doing the swap next weekend and If the car dosent run on that monday Im screwed big time.I guess Ill go with the 750cm since Im running a 383.

 

Here's some information about Edlebrock carbs.

I am running a #1411 750cfm on my 355 but I had to change rods and springs out of the box,but you are running a 383 and it should be just right

 

Thanks guys the 1411 is what Ill get then.

 

good man, that would be my choice too

 

I have Changed my setup since this post,Now I have the Holley 770cfm Street Advenger Carb,And Bolted it stright up and have not touched it Now its been on for 2~Months and still have'nt touched it....Not bad for a Holley

See my new set up that I have done in my Sig.
