Its the high volume GM pump, they have wider gearing and much more pressure/volume. I've heard that they can drain the oil pan if run at higher RPM's too long. If we use this shortblock in one of our cars, I'll change the pressure regulator spring to lower the pressure at least.
DoD and VVT engines are what these pumps come stock on.

No MS3 this time, I might be able to dig up a past sheet though. It would be really close to the Tsunami as far as HP, and maybe a tad less torque. I was most impressed by the Tsunami being that its a medium/large sized cam and making the same power as the bigger cam numbers while still having some decent torque.

I made pretty good power with my MS3, waiting on replacement heads(just ordered today), I'll post up my power difference once installed. 05 version stage1 ls6 heads made 460 rwhp with I think 409 rwtq. Hoping the newer stage 2.5, 5.3's improve on those numbers.
233/239 Vs Magic stick 3. Would love to know that one.
And also as a question, for the MS4, Whats the standard piston to valve clearence with 241 heads? One thing that kept me from looking at it was its huge intake lift and the worry that running a .030 cometic gasket wouldnt be possible.

i highly doubt the Comp 224/224 .581/.581 112lsa im running that i installed 2 years ago has either lobe design. how would i even begin to know? showed nothing in the cam package in regards to that...
benefits and contraints to each lobe design? thanks.

i did a search but cannot come up with the difference between the XFI/XER lobes...

the "Cam Guide" doesnt break out the different lobe design or characteristics...
so are we talking about faster ramping rates, quicker revving cam(s) so to speak? do the assist in benefitting lower RPM power (not power under the curve), meaning where the cam flows around .200-.300 lift, etc.?
thanks for the info.

Apparently XFI are easier on springs than XER.
(I wonder if that means you could use a PAC 1218 spring with them
)
Though TSP are saying they didn't see the gains expected from this new XFI fad.

TSP,
Awesome info! But between the TQ3 and the tsunami, the TQ3 has better power up to 5900 RPMs against the Tsunami. And im just curious, but did the tsunami spike @ 6600rpm's?
The MS4, Tsunami, & the TQ3 produced very good power, but they are all reverse lift cams. What would be the difference if you put the MS3 cam in there, which doesnt have a reverse lift? Would it be possible to put the MS3 cam in on that same dyno and post some numbers so that we can compare them?
....what about the dyno results on the Texas-Giant!?
Thanks again!

I wanna see what the MS4 did with heads and the big headers

Whatever lobes used and mixing of lobes ae not "fad". TSP knows that (LSK/XE-R) cams, so I doubt that any of their cam tech would make a remark like that.
Mixing lobes creates characteristics that a single lobe pattern might not be able to achieve.
Such as a 224/224 that is a no split cam if XE-R/XE-R,
While if XFI/XE-R it is a reverse at .200 and increases trq output in early midrange.
Vengeance knows that as well and is producing good results with XE-R/XE (high lift) mix.
So anyone just looking at .050 cam specs and making a judgement on a cam, is actualy looking at 1/10th of the whole spectrum, basicaly that person is legaly blind
Yes you can (properly installed)

There's something to using the right lobes....otherwise our TorquerV3 and MS4 wouldn't be doing that 
Is it as easy as picking the most aggressive lobe around at any given duration and crossing your fingers that it makes good power? No.
