What gives a cam a choppy idle?
The reason race cars have that rough idle is because the engines used are designed for high-rpm operation. The reason you want to stay away from an increase in lobe lift is because of the changes youll need to make to a stock engine if the cam has more than approximately . 460 inch lift.
Does camming a car make more power?
Are Bigger Cams More Powerful? Yes. A bigger cam will open the intake valve wider, allowing more fuel and air into the cylinder. The larger the cam, the more fuel that is let in.
What is a racing camshaft?
A racing camshaft is a precision product that requires tender loving care in its installation. Before removing the stock camshaft, revolve the crankshaft slowly a few turns and notice the position of the timing marks on the cam and crank sprockets, with the No. 1 cylinder piston at T.D.C. (Top Dead Center).
What is the difference between drag racing and street racing?
Drag racing is generally a sanctioned event, conducted in a controlled setting at a purpose built facility. Street racing is what the name implies. Whether it’s done on a lightly traveled road, a side street outside of town or on any piece of two lane highway, it’s flat-out wrong and dangerous.
What is the difference between a Stage 1 and Stage 2 camshaft?
Stage 1: these are generally considered exhaust and intake modifications to an otherwise stock engine along with the appropriate EFI Tuner. Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination.
Are cammed cars illegal?
yes, unless it comes with a CARB certification number. Any modification is illegal (even just changing the mufflers) unless it’s certified by CARB.
What is a Stage 3 cam?
The Stage 3 cam is designed to work with some larger valves, port work, and upgraded carburetor or EFI system. This cam starts moving the power band a little higher in the RPM range (2500-6000). This is the biggest cam we recommend for a street application. It is used commonly in the race and hot street applications.
How much horsepower does a cam give you?
Does a camshaft increase horsepower? Yes, a camshaft adds 10 to 20 horsepower depending on the setup. To get the full potential of the high-performance camshaft, you’ll have to swap out additional components like the air intake, exhaust manifold, injectors, and valve heads.
Whats the fastest drag car in the world?
If you are unfamiliar with his name, he is still the man who holds the record for the fastest quarter-mile run in history with 3.58 seconds, registered in 1984 at the Santa Pod Raceway. But this run is even faster….More videos on YouTube.

What is the best all around Cam for a street performance vehicle?
Most street driven vehicles seldom see the high side of 5,500 rpm, and most cruise at 1,800 to 2,500 rpm on the highway depending on how they are geared. The best all-around cam for a street performance vehicle, therefore, would be one that has its peak power and torque curve in the 1,500 to 3,000 rpm range.
Why are they called 3/4 race camshafts?
“And then some guys wanted a milder cam that could also be used on the street, so they called it a three-quarter race cam because it didn’t have as much duration and lift,” explains John MacKichan of the Speedway Motors Museum of American Speed in Lincoln, Nebraska. Ford Flatheads were the beneficiaries of the first 3/4 race camshaft grinds.
What is the NHRA Super Street drag racing index?
At NHRA Lucas Oil Drag Racing Series races and select NHRA Camping World Drag Racing Series events, Super Street racers compete on a fixed 10.90-second index.
How to choose a camshaft for an engine build?
Choosing a particular type of camshaft for an engine build is an important decision that has to be made before any other parts are ordered or machined. Choosing a cam requires answering some basic questions, the most important of which is the engine application itself. Are you building an engine for everyday driving?
