Is 40 HP a big difference?
40 hp is about equal to what you can get out of aftermarket parts bolted to a fronty 4.0 short of a supercharger.
It’s an easily noticeable difference..
Will changing spark plugs increase power?
High performance spark plugs for improved engine operation Pulstar spark plugs can give your engine more power, a quicker throttle response, and a more stable, longer-lived engine.
What size carburetor do I need for a 383 stroker?
The Carburetor for a 383 Stroker is a 350 carb., but you would either want a 650 cfm or even more powerful 750 cfm carb for improved performance. Consider that the larger carb will be used mainly for racing applications. No lets mode one to the list of the top-rated carburetor for 383 Stroker small block engines.
Does running rich damage engine?
When running rich, the bottom of your spark plugs can get fouled up with a dry, black soot. This is known as carbon deposit and will affect the performance of your engine. As noted earlier, the catalytic converter’s job is to burn excess fuel before it reaches your tailpipe.
Does carburetor affect speed?
As the centerpiece of old-style fuel systems found on the majority of engines before the mid-1980s, the carburetor plays an integral role in how well—or how poorly—these engines perform. The carburetor affects everything from fuel consumption to idle, acceleration, and high-speed driving.
What causes a carburetor to run rich?
Altitude and barometric pressure also affect air density. Higher altitudes and decreasing barometric pressure thin the air, which causes the carburetor to run rich. Installing smaller jets will compensate for the difference. High humidity can also have the same effect because molecules of water displace air.
What size carburetor do I need for a 350?
A 600-cfm carburetor may perform quite well on a stock 350 Chevy. However, the minute you start weaving in power adders like a hotter cam, a dual-plane performance intake manifold, and aluminum heads you’re going to need 700-750 cfm.
How do you calculate CFM for carburetor?
How to calculate Carburetor CFM. The formula for calculating how much CFM (cubic feet per minute) your engine requires is: CFM = Cubic Inches x RPM x Volumetric Efficiency ÷ 3456. Any ordinary stock engine will have a volumetric efficiency of about 80%.
How do you increase engine power?

What happens if carburetor is too small?
If the carburetor is too small, it restricts airflow into the engine. The cylinder can’t fill up all the way. This starves the engine and results in slow acceleration and a lack of top-end power. A larger displacement engine running at higher rpm will require more air and fuel.
Does a bigger carburetor mean more power?
The smaller carb has increased air/fuel velocity at low and midrange, giving better throttle response. A larger carb will flow more air/fuel at higher rpm and give more top end and higher peak hp.
How do I choose a carburetor size?
How to Choose a CarburetorEngine Size (c.i.d.) X Maximum rpm/3,456 = cfm at 100-percent Volumetric Efficiency (VE)Example: 350 c.i.d. X 6,000 rpm = 2,100,000/3,456 = 608 cfm.

Is it better to run rich or lean?
Running lean can give you more power but to lean will blow your engine. Running too rich can also hurt your motor. Think of it when you are mixing gas for your weed wacker. It is always safe to add a little more oil than not enough to the mixture.
