Has anyone used the SI7 cam??
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??
