Regrinding stock camshafts

[Concept P5]

ok just a question what specs should i regrind the stock camshafts to for a good gain?
i still don't think the MS and FS-ZE camshafts give enough power.
any ideas?
and also what is the going rate for regrinding camshafts?

*sigh* Regrinding the stock cams would be pointless. You would need to add more metal, to increase duration and lift, not grind more metal away.

thats how alot of performance cams are made

How do you increase lift by taking metal away?

if you decrease the base circle of the cams, you need to increase the spacers between the cam and the lifters.

to get a good cam grind, you need to flow test your head, determine what your goals are, and tell your cam grinder what you want. they will then fit your needs and provide you with what you want. oh, and no two heads are the same. so what works on one persons car, might not work on yours.

very nice post !!

remember that furure plans for forced induction will change the parameters set for the cam.
you would want to decide what kind of setup you want now and in the future so you dont spend big time bucks two times.. higher lift for F/I...longer duration for N/A

well its because my friend has donated his stock camshafts to me.....
any idea on how much it might cost?
and any idea on how aggressive i should go for F/I and NA... meaning specs for each.

get in touch with webcams and see what they might reccomend. i would also sugest getting a service manual, if you don't have one already. it will outline what is involved in changing out the cams, as well as setting the lifter clearances.

webcams has a good rep and will help also in determining the right cam for your application. i would also get your head flow tested so you have some info to give them to lead you in the right direction. in order to get max efficiency out of your head or engine in generall there is alot more to it than just stating specs that someone else might be using. like mentioned earlier every engine and head are different. this is a very tough issue without having alot of specs and stats in front of you.
good luck. but if your serious about the work you want to do YOU MUST get more info on the head first
later

I got a spare set and had them hardface welded and reground by Crower. Cost just under $600. Haven't used them yet though, because as everyone else stated there's a lot to do before they'll work. They've been sitting around awhile.

You can spec cams first and build a head to match easy enough. Looks like the TB and intake manifold will need the most attension.

Right after I sent the stock cams out, I found that MMS sells blanks that don't need the weld up. Much, much cheaper that way.
