Has anyone used the SI7 cam?? Just seeing if anyone has used the SI7 cam by Speed Inc. If so how do you guys like it as far as sound, driveability, power?

It has more overlap than an MS3-4, but less than the TRex at 25 degrees. Looks like about 21 degrees from eye-balling the specs: 238/244 .605/.612 110 It is gonna be a top end performer, so get ready to man up and pull your rev limiter a few hundred higher to get full potential out of this cam.
I DD a 244/248 cam with 16 degrees. If you want to know what it sounds like....It is a heavy hitter. I have a link to a vid in my sig for mine. It has a bit more inconsistency in it. I would recommend gearing regardless or a converter...depending on your unannounced setup.
If you are going for the big factor just to do it....You may be miserable. That cam is not a faint hearted one. If you have never driven a major cammed car I suggest doing it before taking a plunge. You might be looking at the SI2,3 or 4 instead depending on your tolerance levels.
If you are asking about driveability...this cam is probably not gonna be your friend, but boy will it have a sweet idle!

Thanks for the replies I am posting this on this forum cause the LS2 LS7 forum is not as busy as this one. I have a LS2, stock LS6 heads, 1 7/8 Kooks Long Tubes, True duals, custom cold air, LS6 intake, ported throttle body, underdrive pulley. I amd debating between the ms4 on a 111 lsa or the SI7 cam. Sounds like to me I would be better off with the MS4? For a little better driveability??
