hi, i just bought some pi cams for my npi stang, other then pulling the pulley, is there any really snag that would come along and slow me down in changing them out?

 

Lot more to it than changing (?) a pulley

 

If you mean pulling the Cam Gears, then yes there is a lot more to it. Use google search and look for a write up install on cams. You have to make sure the timing chains are right for correct timing. Or you'll have problems with your pistons hitting your valves.

 

There is more than one method of changing the cams. Some people change the cams without removing the timing cover. Others will swear that removing the cover is the only way to go. I have good experiences with both methods. With either method, you 're going to fight to remove and reinstall the valve covers. The biggest concern however, is that a mistake with the timing chain or cam gears will screw up the timing.

 

if the timing is off one tooth, what will the symtoms be? ive heard that it can be off 1 tooth and still run but run like crap.

 

Why would you want to find out? Just don't do it.

 

how would you change the cams without removing the timing cover?

 

You can install cams without removing the front cover, but they will not be properly degreed. IMO, all cams MUST be degreed, or else there is no real reason to buy cams based on specs.

 

I know where you 're coming from, but in this case the OP is only referring to a $50 set of PI cams.

 

I know, and that's understandable. I tend to "inform" all people about degreeing cams, no matter how tame/wild the cams may be. By informing them, they'll understand the concept, and then can make a more informed decision on how they plan to attack the installation.
