Need some help picking cam and supporting mods
Seems like the valve spring failure is more common than I thought so will be swapping them out before they go. Hopefully they can hang on another week!
Since I am half way there, might as well do a cam to get some nicer sound and a little more power. The car has a drop in K&N zip tied on and the borla straights over the axle. Got it tuned and it made 386. Car is my daily so still want it to crawl around parking lots. No headers and want to keep it that way.
I need some help picking a cam to make some more power and take care of the valve spring issue. What other parts should I order since it is being opened up?
The vengeance racing and BTR cams seem popular and look like they are making great power.
Help please

personally I would do headers first, I would want to increase the amount of air the engine could effectively move out before I increased the amount of air it could take in... or even better do the headers and cam at the same time... along with the springs you should get a good set of hardened pushrods, beefy timing chain, and might as well replace the oil pump for insurance since you are already there... valve seals isn't a bad idea if your engine has high mileage... the stock balancer sucks so might as well replace that with an aftermarket unit that won't come apart and wobble

They seem hard to install and way too expensive. Also dont want car to be obnoxious loud. Local z owner by my neighborhood has mild cam with intake and tune making 420 wheel. If I can get close to that and have the peace of mind of newer valve springs, I would be more than happy.

You sure he doesn't have more than that? 420 at the wheels with just a cam and intake sounds pretty strong.

Not sure what the specs of the MS4 are or if I am limited to size of cam because of the headers.
Any ideas on cam size I should consider?

an ms4 is a donkey d*ck cam for a car with stock heads and manifolds, that car should make it to the upper end of the 400's if it was set up right... it probably sounds mean but it's choking the engine, personally I would get something smaller unless you are going to do the other necessary mods to let that cam work as it should

Is he running a C5 Z or a newer? I asked because a C5Z making 405 horse stock isn't the easiest to get 420 to the wheels with just a couple of mods.
Now a newer one with an LS3 on up might be different.

My XS Power headers fit great, cost under $750 shipped, and took me 2 hours to install. The OP needs to choose what will make him happy of course, but there really are only benefits to long tubes. I think they are worth the price for how much easier they make spark plug changes alone

Headers are expensive and I about cringed when I bought mine but installing headers is actually alot easier/quicker than a cam swap. Swapping valve springs is the quick and easy part of the cam swap. It gets time consuming and labor intensive when you begin taking everything out the way to get the stock cam out especially the steering rack. Headers with your Borla may be too obnoxious for you but you could always sell the Borla and switch to something milder if that becomes a problem. Just my .02 but either way atleast those valve springs will be fresh and you will have peace of mind.

The numbers did seem really high for his set up. I was just speaking to him and he mentioned the cam he went with is similar to the MS4 but larger split to be able to work with stock exhaust.
I did consider the XS headers but have read some posts where installation is a nightmare. Dont want to chance having to cut car up to fit these headers.
If I end up doing a cam, it is going to be something mild. Somewhere in the late 210s early 220s with low lift. Timing chain sounds like great preventive maintenance as well!
