ms3 vs ms4 w/stock heads
. I know the ms4 makes more power but what about driveability and wear and tear? I'm going to get the package when I get the cam. What about tsp custom mail order tuning? To answer your question though I'd definitely try out the MS4. You gotta remember that the ls1 head definitely works well as cast and seems to like these new lsk lobe cam designs. More torque always makes for more tire smoking fun too
