MS4 Gains?
people claim a lot of power when it comes to cam only applications. i wanted an ms4 for a long time till i read up on the trex, and that immidiately caught my interest...
heres my question...
is there anyone out there who has a ms4 only car with 'no other changes to an ls1 engine' thats making anywhere near these gains?
my friend has a stock catback on his car to make it quiet around town. with pacesetter LTs, 3inch custom ORY, and a cutout. with cutout closed he lost 40rwhp!!! that is a FAT difference! i would not put an ms4 without anyother mods in the car. put all the exhaust parts you need atleast so it can breathe. these big cams dont like back pressure. and you will not make any powere if you leave everything else stock. what they mean by not other changes is probably heads, intake, and stuff like that.

and put the stall in first! u will be happy you did. driveability sux wit a cam and no stall. i did it for almost a year. when i finally put my stall in i was so much happier, and the car go so much faster. i can shread 315 drag radials like nuthing.
i have the ms3. i love my cam. and they say the ms4 will out perform the ms3. but i will prove that statement wrong!
Good luck.
Yes, this cam needs to breath, and yes you will be reving the engine to 7k with the right mods. In an auto, I would think a 4,500stall and 4.10 gear would be ideal....If you think a 4.10 gear in a ten bolt is a smart idea...
