MS4 cam and stock block?
MS4 cam and stock block? I have decided to use the MS4 cam but I was wondering if I go ahead and install it along with the stock heads and intake will this be ok until I get the TFS 215 heads(I really have to save up for those)but I will be installing pacesetters long tube headers,3" true dual exhaust with bullet mufflers,Yank PT 4000 stall,trans go shift kit,tranny cooler,dry nitrous kit, and I have a 02'WS6 T/A that all this going into!

Most cams like that are going to be robbed of low end. IT will still pull, but not like a 224 does down low. I know that I chose a cam that gives me good power down low....if you consider low 3600rpms.

Otherwise, there is very very few ways to optimize DCR at 10.1:1 SCR, unless you want a tow cam
FYI, even the stock cam is not optimized for DCR, heck it doesn't even reach 8
Speaking of optimizing, who is gonna put 2.08 valves on a 3.905 bore???

Most of the posts I've seen from people who actually have the MS4 are saying it's not got the low end that it was marketed and claimed to have. But I'm still highly intrigued by the cam. I can't wait to see LS144's car with that cam in it. Looking at valve events, I think there's a nice LSK lobed custom grind that would be all around slightly better within a usable powerband (<7000 rpm) by looking at the valve events.
