69 bee with a mostly stock 383.want to give it a little more punch.looking at an edelbrock intake.will it make a difference?which one?thanks for any input.david
 
Put A Performer Rpm On Mine With A Holley Carb
Night And Day From The Offenhauser Dual Quads
Much Better Driveability And Power
Mines Stock Other Than A Cam And Headers
Although It Was Way Over Carburated Before

Good intakes/carbs usually help but thet are usually part of a total package with a mild cam and exhaust. Even with a stock cam, an intake, carb and headers will usually make a very noticable difference.
 
I agree that you won't notice much just by changing the intake. I'm running high 12's @ 108 with a factory iron intake so that tells me it's not as bad as one might think.
 
If you are looking at Edelbrock the performer 383 is designed to work in the idle to 5500 RPM range. This is probably where your mostly stock 383 lives. The performer RPM is 1500 to 6500 RPM so you would need a little more cam to take advantage of that. Victor and torkers are designed for over 2500 to 6 or 8000 RPM so thats probably well above mostly stock.
 
Generally, a high performance intake manifold is a part of a team of parts designed to increase engine performance. Remembering that an engine is basically an air pump, that means the more air it gets in and out, the more efficient it is. Intake manifolds combined with things like bigger carburetors, increased compression, better cylinder heads, better camshafts, improved exhaust manifolding or headers all work together to make an engine more efficient. When I say more efficient, I am not talking about MPG. I am talking about volumnetric efficiency, or horsepower to cubic inch ratio. This is why it's so important to match components that all have a common goal. An 850 double pumper on top of a single plane intake bolted on stock heads on an 8:1 compression stock engine with big tube headers is NOT a pile of parts with a common goal in mind. This is why a lot of people are often disappointed. They think for a few hundred dollars, they can have 500 horsepower and it just doesn't work that way. What you need to do is devise a plan of what you want to accomplish. Research parts that will help you acheive that goal. It will take way more than one part to accomplish it.
 
Thank you Rusty good advice.part of my problem is that I don't know what was done on the rebuild of the 383 before I got hold of it so I am looking some basic upgrades to start.thanks for all the advice and suggestions.david
 
My advice would be to start with a compression test with what you have now. If it has 150 or greater, someone built it with performance in mind. Less than that and not so much. But that still doesn't mean you cannot improve it with bolt ons. What I would do either way would be a good set of headers FIRST and go from there. If I had to choose one single bolt on above all others, headers would be it. Of course then you will need more carburetor because headers will lean the fuel mixture out. Then comes the intake. With those three things right there, you should see a nice improvement in performance.
