Can a cam swap be done on an LS engine?

Can a cam swap be done on an LS engine?

This allows you to remove and replace the camshaft without having to remove the cylinder heads. So let’s quickly run through a cam swap on an LS engine. The first step is to drain the coolant from the block and remove the water pump and harmonic balancer.

What kind of CAMs do I need for a LS3?

Again, drivability can also be greatly affected by the tune of your engine regardless of how mild or crazy your cam is. For the most part, it’s easier to design a cam for a specific combination of heads, intake manifold, and valvetrain that will always be used on a particular LS3.

How many horsepower does a LS3 engine have?

If you “change the specs on the piston compression ratio and the camshaft, the engine can be pretty flexible that way.” Thus, the LS3 block is used for its light, aluminum construction that is good for 800 HP or so. After 800 HP, you’d rather have a iron-based LSX block, which is stronger, but a lot heavier.

How to remove spark plugs from LS cams?

The first step is to drain the coolant from the block and remove the water pump and harmonic balancer. Next remove the valve covers and all 16 rockers and pushrods and to make spinning the engine easier, remove the spark plugs. Now spin the engine over at least three times.

Do you need to change valve springs with LS cams?

If you’re not worried about changing valve springs or needing other mods, then you might want to check out the Black Magic line of LS camshafts. Like the LL-series cams, these are derived from the lobe design utilized in the Voodoo series of cams.
