Just put 50 miles on the MS4 cam/Rod bolts/K-member/motor mounts/Torque Arm :) I didn't expect the cam to be THAT much meaner sounding than the MS3 . . . but DAYUM!!! 
Because I'm running 2 mufflers in series the interior noise didn't increase by much at all . . . but the outside note is just WICKED 
Right after my mechanic started it up for the first time he called me right away to tell me it sounded like an old-school Big Block idling
I noticed a big difference in the part-throttle driving. A lot more low-end torque
By the butt-o-meter I'd say it pulls a good 15-25 more ponies from 1300-3000 rpm's at part-throttle over the MS3. That's REEEEALLY NICE
I was pleasantly surprised to see that the MS3 tune I had running perfect actually worked almost spot-on for the MS4.
I might have to tweak one table in the idle and that would be it.
I haven't gone WOT yet but I'll report back once I get the alignment done and my lugs from Jegs (ARP wheel studs needed some special long tapered lugs that NOONE in South Florida carries
).
After I do a full tweak on the part-throttle and WOT, I'll dyno my set-up and post the motor numbers
The poly-eurethane motor mounts are rock solid. They increased interior vibration substantially but I happen to like it.
UMI'S K-member, Torque-Arm, and Driveshaft Loop are TOP quality pieces . . . the red undercarriage looks pretty sweet too

You wanna talk about poor . . . my Woman wants Heads, Cam, and full bolt-ons on the Red WS6 and we'll probably put Turbos on the Silver WS6

so what do you suggest for the valvetrain upgrade for this ms4 cam?
i have a tr224/224, but i want to sell it and get a bigger cam.. and this ms4 has really got my attention...

I'm running Manley Valves with PP .650 lift dual springs.
I've been running the same Thunder Racing hardened pushrods for over 60K miles.
My Thunder pushrods have been through 4 cams and 2 motors.
Cold-start, hot-start, ANY-start is BETTER than the MS3 cam . . . which was a pleasant surprise

Fly-cutting is not necessary if one has stock heads, TSP Stage I LS6 heads, or un-milled ported heads.
I wish my Harlan shift-light went higher than 7K rpm's 
My light goes off almost 200 rpm's early, so for me to hit 7100 rpm's I need to wait a bit with the light on and, literally, play-it-by-ear with my motor.
My impressions UPDATE:
The MS4 shifts more violently than the MS3 did . . . I like dat
I know I said it before but that whistle of the intake is sweeeeeeeeeeet

Ask John, Jason, Zack etc. from TSP to verify.

As I've stated numerous times in this thread and others like it, the MS4 acts better, is easier to idle, and makes more torque through the entire rpm than the MS3 did; remember, I've had both cams now (including the 231/237
)
