Was wondering about power
 

I would like to buy a ford b303 cam for my car. I was wondering about what the power diffrence between the stock cam and this cam would be. This would be on a basicly stock motor.
Thanks for any help.

Without heads and an intake swap, a cam upgrade is virtually worthless.

Cam
 

Very true Jeb, granted it sounds cool as hell, but if I could go back, I would have gotten heads and an Intake first. Basically no noticable power. Later,

Leave it alone

For what it's worth, I can confirm the previous posts.

The stock cam is quite aggressive and matched perfectly with the stock engine configuration; a cam change - alone - will do nothing for power and in some cases, you get could actually get slower.

Not recommended without new heads, intake, exhaust - minimum.

My mustang has equal lenght shorty headers , a off road h pipe 373 gear set and I have had the upper intake extrude honed and the lower i have ported my self. The heads have all so been not ported but made really smooth. Do you guys still think i will not see any improvment with a cam change. Thanks again.

To cam or not to cam...
 

Not enough to justify the labor and expense of changing the cam. Again, unklike some engines, the 5.0 HO (stock) cam is very efficient and serves well until/unless you get to big HP mods.

Any gains you get will be at the topend of your power range and you will lose some bottom end with a cam swap. wait till you are ready to do heads that a great time to do a cam swap to compliment the added airflow.
