MS3 Driveability?

[WS6ICK2K]

I was looking in to a cam swap. Only mods are LTs, TDs, CAI and free mods. I have heard alot of good things about the MS3 cams, and was wondering how it will effect gas mileage and driveability. Car will mostly be a street/ strip car that I mostly only drive one or two days a week and maybe to the beach.

I would like to also do a head (maybe 5.3s) swap later on down the road but I'm a little short on $ for that rite now. I know that LSA determines alot of street manners and gas mileage. What would you guys recomend? smaller cam, higher LSA?

depends on what you consider "drivable". I am looking at an 00 SS with MS3 and PRC 5.3 heads. Hes making 454 rwhp. Sounds mean as hell but the cam is pretty big. The guy told me his tuner bumped up the idle a lot because he was afraid the car would stall if you rev it up or quickley come to a stop.

Yea I have heard of people having to drill the TB just to let enough air in to get it to idle.

Not a fan of drilling the TB blade.


Too much cam for a DD in my opinion.
The MS series cams are for drag cars, with steep gears, and great heads.

Those cams can be fairly streetable with a great tune. Mileage will suffer.

A local guy has one. Took him a good 5 minutes on a 50 degree night where it would run...
