I have a 670 lift cam in my garage, what modifications do I have to do to my mustang for it to perform right with this cam, not too familiar with this stuff.. its an 88 5.0, mods are listed; edelbrock performer intake, holley 650 4b carb, exhaust, msd ignition,
Thats way too much cam. You would deff need to get different pistons and god knows what else. Is it even a roller cam? I wouldnt put nothing but a roller in that block. If your wanting a new cam for your car i would go with a roller under a 512 lift. Trickflow or ford e or b cams..... Im sure theres other people that can help chime in on this matter.
I'm guessing with that high of lift it is probably a solid lifter cam. You need a roller cam and nothing that large. With your mods, you do not need a different cam if looking for performance.
For around 10-12hp 1.7 rockers and it is alot easier than swapping a cam. What are all the mods you have now? Do you have a Performer or Performer RPM?
I have a performer, I was told the car had a small-mild cam so I was thinkin roller rockers would be good, current mods are exhaust, intake, holley 650 carb, msd ignition, cold air intake, and 3:73s, I was also thinkin about underdrive pulleys?

So more than likely it is a stock cam, I've heard the "mild cam" story from people selling cars and it usually ends up being a stock one. A better intake would be a Weiand Stealth, some pulleys will pick you up some power, maybe around 15hp.
What Dave was trying to say was if you go with a 1.7 ratio rocker, you won't need to change the cam. 1.7 rockers will give you about all the extra lift you would want with stock heads, valves, springs and pistons. And the rockers are way easier to install than a cam.

Yep, rockers will bring the lift from .444 to .472, for small performance increase. Really with stock untouched heads a camshaft change is NOT a good bang for the buck mod. It would be one of the LAST things I'd change.
The 1.7 rockers may not even bring much of a power difference either depending on the condition/miles of the springs in the stock heads.
Personally, I'd get a Weiand Stealth intake, pulleys, then get the timing/fuel dialed in 100%. If that carb is not tuned correctly and the timing is not optimal you are losing alot of power right there.
