What is the cam lift on a stock 350?

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 (GM has a newer version of this cam with less intake duration for use in 9.0 -9.5:1 compression engines.)

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 a Comp engine?

Engine Comp allows you to distribute the workload of a project across multiple CPU threads using the new TouchEngine. This means that if something heavy happens in one of your Engine COMPs, it won’t slow your whole project’s FPS down to a halt.

What makes a cam lopey?

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.

Can you put a Stage 3 cam in a stock engine?

Sure you can. Brahmus has stage 3’s in his stock block.

How can you tell if a cam is a comp cam?

COMP Cams uses two-number designations for all its engine families. The LS engine is designated 54 and this number is generally the first two numbers that define the actual cam part number. Other examples include small block Chevys -12, big block Chevys -11, and 5.0L small block Fords -35.

Are all SBC cams interchangeable?

There are several varieties of small block engines currently in use in the aftermarket. Although they mostly use the same block, the cylinder heads are very different and require totally different camshafts.

Why do cammed engines lope?

Again, keeping all else constant, more duration will make the engine less efficient at low rpm, with more overlap dilution of the induction charge, and the later intake valve closing reducing the trapping efficiency. Therefore, a long-duration cam will cause rough running at idle (lope) and a loss of low-rpm torque.

What are the specs of a Big Mutha thumpr Cam?

Big Mutha Thumpr Cam (#PN 12-602-4) 295/313 Duration. 2500-6500 RPM Range. Lift: 0.500 Intake/0.486 Exhaust. The basic science behind the Thumpr Cams is not a new one. The Thumpr line delivers true high performance engine sound by “tightening” the lobe separation angle of the camshaft.

What is a thumpr Cam?

The basic science behind the Thumpr Cams is not a new one. The Thumpr line delivers true high performance engine sound by “tightening” the lobe separation angle of the camshaft. This creates more overlap between exhaust and intake events and more “cool” performance sound.

What kind of camshaft does Comp make for a 4 way Cam?

COMP Tech: 4-Way Camshaft Dyno Shootout! The Thumpr Camshaft line of hydraulic roller camshafts from COMP Cams, introduced in 2006, has been a huge success, well beyond the company’s original sales estimations.
