What makes a cam lope more?
Lope is a result of the intake and exhaust valves both being open at the same time. This is called overlap. Mild cams have little or no overlap at any valve opening that makes a difference. Hotter aftermarket type cams have a lot because it aids high RPM breathing.
What does lobe separation do for a cam?
Typically, narrower lobe separation develops peak torque at lower rpm and widening the separation tends to build peak torque higher in the rpm range. Nitrous engines, which make plenty of power and torque, often run wide lobe separation angles to moderate cylinder pressures and temperatures.
How can you tell a cam lope?
What Determines Cam Lope? In the case that the overlap size is strong enough you can make a stock cam lope by tightening the LSA, but the duration of the lobes would also indicate the need for a cam lope with stock LSA.
How much lift does a stock 350 cam have?
The 350hp/350 cam had . 450/. 460 lift. (GM has a newer version of this cam with less intake duration for use in 9.0 -9.5:1 compression engines.)
What happens when you advance a camshaft?
Advancing or retarding a camshaft’s timing from its original “zero” position causes the valve events to happen either earlier or later in the engine’s cycle. A camshaft that is advanced four degrees will cause each opening and closing event to occur four degrees of rotation sooner than before.
Can you put a bigger cam in a stock engine?
Of course it can be done…But, I would consider replacing the valve springs, the stockers are probably not going to like the extra lift.

What is the RPM of a Chevy 350 Cam?

What is the lope on a solid lifter cam?
The cam was the GM 425 HP solid lifter. The lope comes from overlap which allows exhaust gas to contaminate the intake charge. Widening the LSA reduces overlap and narrowing it makes it worse. Choosing a cam based on “lope” is not going to get you better performance. Racing cams sacrifice low speed performance for high rpm power.
