I have a ms3 cam, but was wanting to know what lsa is and what it does in sound. Im guessing its the lope. I am wanting a something that lopes. So what lsa sounds the best? Thanks Justin

 

LSA stands for lobe separation angle. Our most popular LSA choice for the MS3 camshaft is 112. Feel free to give me a call Id be happy to help you out with your setup.

 

Get on Youtube... there are hundreds of idle/WOT clips of LS1s with various camshafts so you can get a feel for what you want before you buy

 

Overlap is determined by LSA and the durations of the intake and exhaust lobes, so by itself an LSA might not really have a unique sound.

 

So a 114 lopes more than a 112?

 

112 more than 114

 

If the cam in question has no overlap on either LSA then neither may lope. But lower LSA has more overlap, or less negative overlap.

If you are asking specifically in regards to an MS3, then on a 112 LSA it has 15.5* of overlap at 0.050" and on a 114 LSA it has 11.5* at 0.050".

It also depends on if you were to set the idle speeds the same as lope will disappear as you move the idle up.

 

Thanks im going to stick with the ms3
