MS4s accessories..What do i need?
ms4 on a 111 is a beastly cam for that 98 shortblock. to take advantage of a cam that large you'll need to be willing to spin 6800 rpm. either way, i hope you know what you're getting into, but given your knowledge regarding pushrods, etc, i don't think you do. it sounds to me like you might enjoy their torquer series of cams more, as they don't require such high rpm and will drive much better in the lower rpm. also, you will want some 410 gears with that cam. the 342s will be a dog and take what seems like forever to wind out.
you'll need a cam
dual spring of your choice
retainers (typically included with the springs)
gaskets
hardened pushrods
i would suggest a new oil pump
ls2 timing chain, no sprockets as already mentioned
if it were me i would buy:
a set of patriot gold duals
use texas-speed's custom cam designer for a cam of my choice
tsp hardened pushrods
lingenfelter ported oil pump
gaskets from GM
ls2 timing chain from GM

Good Advice.. I did a MS4 with a 110 LSA (Yes a 110 LSA). Cam rocked solid with 3.23 gears and a 4,000 stall.
My block was a 98 with over 100k miles.. One thing They forget to mention is the 98's are known to have rod bolt stretch.. When I did my cam swap I added ARP rod bolts.
Just know what your getting into.. when you put in this cam.. You need a tune.. Tunes are not cheap.. It will run you about $400 for a dynotune.
With this new power you need to ask yourself if your clutch will handle the power. If the motor is high high miles and will take well to being spun so high.
If I was you I would not go for the Hard lope, Big cam that needs to be spun..
Yes you can get away with it... But you will honestly enjoy a more mid range powerband cam. I had the cam in for 4 months and I spun a rod bearing. Now im $15,000 into a 408 t56 swap build..
lolIts your ride. Do as you want.
How much power do I want?
How is the car going to be used...street/drag?
How high do I plan on spinning the motor?
These things will dictate your cam choice. I would get a cam speced out for your preferences.
We'll I do have another car that i can drive so the trans am will not be my daily. And i love the sound and power of the big lopey cams. It will be taken to the track a lot eventually (waiting till i pay it off). But since it' a 98 the rod bolts do make me nervous. Could i go with an MS3 instead? I mean i don't mind a cam that makes power sooner, but i do want big power considering the fact i dont have money to supercharger or anything. More than likely i will be adding spray too.
consider gears
shift rpm
it's your car, do as you wish. i would suggest consulting predatorz or patrickg about a cam.

get a 224 cam i went from torquer 3 stage 2.5 5.3 liter heads and fast 90/90 to 224 cam ls1 intake. To be honest i am happier with the power it makes down low and midrange a lot more than then tq3. 224 make good power has a nice chop to it
What kind of numbers are you making? Main reason for my wanting a MS4 was I would like to be around 400Hp
i know a guy making 401rwhp w/ a torquer v3. sounds good and makes good mid range power. i would suggest tsp's 233-239. that imo would be an awsome cam for m6's and still what your looking for. its bigger than the torquer's but smaller that the ms3/4. i ordered an ms4, but im an a4 and ordered a 4000 stall to always be in the power band. check out that cam, i think you would really be happy w/ it! i know your on a budget, but remember, dont go cheap on anything, expecially the internals.
dude you need to do some searching. it's proven time and time again that 224 cams put down ~390whp consistently on very simple setups. with the new lobes, there are MANY ways to reach 400whp, the ms4 would be my last option for this goal.
Yeah, fully CNC'd 5.3 heads will flow good numbers and increase the CR due to smaller combustion chambers. Plus they are very affordable.
