The cam is the heart of the engine. If the cylinder heads can flow up to the valve lift, the duration controls where the power is made/and too a smaller part the lift control how much power is made in that powerband. AN old school rule of thumb is 10 degrees is equal to 500 rpm bump in powerband.

What is the difference between high-lift cam and low-lift cam?
A high lift cam lifts an engine valve by a higher amount than a low lift cam.
What does it mean when someone says a car is camming?
Camming means cruising in your Chevy Camaro. To say a car is a "Cammer" means it has a high lift cam. So I would assume when someone says it is camming they mean the engine is loping due to the high lift cam installed. An engine with a high lift cam will not idle very well, but does run well at high rpms.
How do the cam profile influence the performance of internal combustion engine?
Cam lift and duration is how wide the cam opens the valve, and how long the valve stays open. The longer the valve is open, the more air\fuel mixture can get into the cylinder. More fuel means more power.
What is cam duration?
The cam duration is the degrees of crankshaft rotation that the valve is lifted of it's seat. Most accurate way to compare cams is with duration at .050 inch lift. How many degrees from when the valve is .050 off opening to when the valve is off the seat .050 during closing.
What should the engine compression for a 440 engine?
Depends on the year, cam, compression ratio. engine warm, 130-165psi, long duration lowers psi, overlap increases psi., solid cam with same duration would be higher than hyd. due to increased valve rate. All reading should be +/- 10%
Where can you find a good website to figure out the horsepower for a Chevy 350 with a 488 510 lift 300 310 duration cam in a 1972 Chevy scotsdale long bed pick up?
List the model year and vehicle the engine is in and I can tell you the H.P.
Will any small block camshaft work on a 305 motor?
Any cam will fit in the hole, but that's not to say that it will produce the right amount of lift and duration to suit the motor. It's also possible to put in a cam with so much lift it will cause the valves to hit the pistons.
Camshaft with the numbers on top of cam is 115850 and the bottom is 250695 can someone please tell you the size of it and the ratio please?
if it is a small block chevy cam it should be .422 intake lift .442 ex lift .050 duration 204 on intake 214 on exh on a 110 lobe center hope that helps
What does it mean a engine is cam out?
I would assume it means the cam has been removed. I have never heard the term used in this manner.
1996 Chevy 350 vortec K1500 will a crane powermax cam work in it without computer adjustment specs are adv dur int exh duration 260 270 050 dur int exh 204 214 valve lift int exh 112?
If you put that cam in your engine it will never run as good as it does now. You will have nothing but problems.
What does a cam do in a engine?
Cams are devices that transfer rotating motion to linear motion. As a oval shaped cam is rotated against a roller, the roller can move a lever with each revolution. In an engine, the cams are used to lift the valves that open the inlet and exhaust ports.
What valve spring can be used with a roller cam?
vale springs dependon what lift your cam is . need to know what lift cam it is where can get the correct pounds spring if not can have one BIG HEAD ACHE.
