O.K., I am trying to find out which is the best all around cam on performance between these two. The MS3 from Texas Speed or the SI6 from LS1 Speed cam? I am trying to stay in the mid to high 23X range and will be using the cam for street/strip use. It will be on a somewhat daily driver. Here are the specs for the debate:


MS3 ------------- SI6
237/242DUR ------ 235/240DUR
.603/.609LIFT --- .621/.609LIFT
112LSA ---------- 111LSA


Chime in guys!

i would say the MS3 just cuz its more popular. never really seen much people run the SI6.

Had the MS3 on a 111 LSA before the T rex and I liked it. So between the two I vote MS3.

I'll be purchasing the MS3 myself so u know which one I voted for! I was between that one n the F13 but decided on the MS3!

So do you all think these cams match up since the SI6 is a 111LSA and the MS3 has a 2degree duration diferrence? LS1SPEED, you guys need to chime in....

That looks pretty good. Where did you pull those numbers from?

I just split the difference between the 2 cams specs that you posted

My bad. IMO though both these cams have 15.5* overlap on comp lobes, they are going to drive and perform damn near identical. I say go with the speed cam. theres too many MS3's running around this board as there is. I have a speed cam and its working. Either way you're going to get a good cam.

Cam only 2002 Z28 M6, headers, lid and SI6


I checked pistons to valve clearance with SI6 cam .070" Intake .100" Exhaust, with stock 241 heads and MLS gakset.

Add AFR or Trick Flow heads, and the results follow.
