I bought a foxbody about a year ago. the guy said that the motor was rebuilt and a better cam was installed and he said it has to much power for him, In fact he said "when i had my new bug before this i thought it was fast till i got in this" Lol anyways. the guy i bought this was a gay dude so i would like to find out what it has in it without having to take the cam out of the motor

I think you'll have to pull it, if I remember right the part# is on the backside.
possibly you could measure max lift on intake/exhaust (somehow factoring in the hydrolics of the lifters) then compare to different cams specs. IDK.
 
Rarely is there ever a part number on a cam anywhere that's useable.

You'll need your grandfather to help you put the degree wheel on and get it setup. Then pull the valve covers and put a set of checking springs on the valves for the number 1 cylinder. Setup the dial indicator to measure the lift on the pushrod side of the rocker arm of the intake valve. Turn the engine clockwise until you see the smallest amount of lift on the dial indicator. Write down the degrees indicated on the degree wheel. Be precise. Also you never, ever want to turn the engine backwards ie: counter clockwise. There is probably some slack in the timing chain and that will give incorrect readings. If you have to redo a part of this procedure turn the engine completely over.

Okay, now turn the engine until the dial indicator indicates .006" of lift. Now write down the number of degrees the engine has turned from initial lift. Next turn the engine to .050" lift and again note the number of degrees the engine has turned from initial lift. Now turn the engine until it reaches maximum lift. Make a note of the max lift. Now continue to turn the engine until the lifts drops back down to .050" of the base circle (no lift). Make note of the reading on the degree wheel. Now turn it to .006" and do the same thing. Then turn it to 0 lift and make note of the degree wheel.

Now that you have all of the readings from the intake valve swap the dial indicator over to the exhaust valve and do the same thing.

When you have all of your readings come back here to Stangnet and we'll see if we can figure out which cam you have.
