I know this question is asked frequently but can any one give me a complete list of supporting mods i need to buy so my ls1 with stock heads support the ms4 cam...

 

You will need a good set of springs and pushrods. I will not weigh in on the ms4 itself as most have had it fit and some have had issues. The issues could have been improper install or the normal use of a 5.3 head to gain compression without flycutting or getting the heads set up right.
If you are looking at purchasing new we can get you a cam that makes very similar power and sound for less $$$ invested.
Otherwise for just the springs and pushrods check out sale thread out!

First and foremost, you'll want to address the exhausts side of it. Long tube headers are going to be a must. If you're looking for budget headers, Speed Engineering has some 1 7/8" headers for right at $300.00 shipped. Along with that, you'll want to either upgrade the y-pipe, or run true duals. Texas Speed, along with a few other companies, offer true dual setups for f-bodies. Assuming you have a Trans Am (based on the username), a SLP lid and aftermarket filter would be good, as well as new plugs and wires (you would replace those when you install the headers/exhaust). Like coSPeed2 stated, to run that cam, you're going to need an aftermarket spring kit, upgraded pushrods, LS7 or other aftermarket lifters, and the trunion upgrade for the stock rockers would be a good thing to do as well. You'll need an upgraded timing chain as well (LS2 would suffice). Texas Speed also offers a "cam install" gasket kit that you'll need as well.

 

You dont have to do all that at once though. You can do it in stages. The tuning is going to be the most crucial part honestly

 

True that on the tune. Don't be like some of these guys and run around with a cam like that untuned. That's just asking for trouble.

 

I agree with cospeed here. There are much better cams out now that will do what the ms4 did and be a lot more streetable. what are you looking for? if you are dead set on the ms4 phoenix's list is a good start

 

The main point I'm trying to make is don't do a cam install unless you've already done headers/exhaust at the least. Do they make cams that will work with the stock exhaust manifolds, sure they do, but unless you live in California or somewhere else that has super strict emissions, I wouldn't ever consider one. Since you are brand new here, I'd suggest reading through all the "stickies" in the Internal and External section, going through the Dynometer section to see what other combinations have put down, and just generally searching and reading as much as you can before making a decision. It would also be good to get with a site sponsor to talk things over. Make them privy of your goals for the car, is it a daily driver or more or a weekend warrior, what RPM range are you looking at, will the car see the track any, are you chasing a dyno number or specific ET, what are your future plans for the car, etc. Answers to those questions will help you and the rest of us lead you down the right path.

 

you can run any cam on stock manifolds and exhaust. it may not perform but why buy everything cheap just to get the cam in? you can get by so to speak with a minimal amount involved and go from there. buying cheap chinese headers over some better ones just to get them on with the intention of upgrading later wastes time and money.

 

Are you kidding me. You mean to tell me you would not 100% say that you have to have headers at a minimum to run a cam the size of a MS4? And tell me one bad thing about the Speed Engineering headers, other than they are made in China? Go check out the numerous SE threads about how much everyone who has them loves them, how they fit like a dream, and how they are high quality. Not everyone can afford ARH or Kooks headers. The TSP and SE headers do just as good at a fraction of the cost. You can't put the cart before the horse when it comes to a cam like the MS4. I can say without a shadow of a doubt that anyone who knows anything about modding these LS engines is going to tell you that headers are a must with that cam. OP, please don't put a MS4 cam in without the appropriate bolt on mods first.

 

Dont do the ms4 at all lmao.

Even if you went with cheap headers first you wouldnt save any money vs manifolds. Headers are headers, some campanies may make a couple ponies more but mostly it will all be the same. The SE 1-7/8 ones are fine, and I thats coming from someone with ARH's. if you do a big cam and then decide to do headers later on theres going to be a LOT of work required to the tune which will eat up quite a bit of money. A touch up tune for a header swap shouldnt cost really anything. Now getting a tune for a big cam and manifolds is a waste of time and money lol

 

You can run an ms4 on stock manifolds. I wouldnt recommend it but i sure wouldnt say you literally cant. as for the rest i cannot say and was not naming tsp headers or the speed engineering headers. you sure took what i said to heart just because i didnt agree with you. Calm down. Not everyone is going to have the same ideas. Alot of larger cams like that require bigger injectors and a walbro 255 and hot wire kit to replace the tired 12 year old fuel system but you hardly see people doing that. You didnt sugest that either. Most people overlook that part even "tuners". Im not screaming buy from us please but i stand behind what i said even if you read too much int it.
now ive likely rubbed you the wrong way and you can hold that against me til baby jesus comes back, but it wont change what I just said. what i suggest and what can be done and maybe even what should be done could be all different. i didnt suggest he use a stock exhaust. he should use some sort of at least 1 3/4 header prob yes but not everyone can drop all that at once. I just said it could be done

a header swap is def no small undertaking esp if you have to pay someone to do it. and doing it twice? ha.

 

If the OP can't do it all at once, then he'd be better off doing it in stages; bolt ons being stage one and cam being stage two. Yes, injectors and fuel pump will also likely be needed. Lots of guys run stock injectors and pump, but the injectors are maxed out and at a duty cycle I personnaly wouldn't feel comfortable running at. I know a MS4 cam with stock manifolds can be done, but why the hell would you.

As far as your comment on the "cheap" China parts, please enlighten me on what you were referring to? Yes, my assumption lead me to the SE headers, but was my assumption wrong?

 

Pacesetter is one. OBX is the other. There are many many more...
I did recommend doing it in stages.

Everyone will have their own way of working out their modding addiction.

I have never seen nor sold the speedeng headers so I have nothing to say about them.
