cam and crank gears , and cam change help

[MrPs97]

I am about o change out the timing chains on my 97 mustang (already has PI swap ) . I was wondering if I need to change out the cam and crank gears or just the chains , guides and tensioners ? The PI engine I have is from a Crown Vic so I was going to put some 2003 Mustang cams that I bought also . Any pointers on doing those ? Thanks in advance for your help .

Tensioner and guides are the only thing that fail. Cams are the same as far as I know. Bolts aren't reusable

Thanks for the info . I was told by someone that the cams were different . I guess I can resale the ones I bought , and the other set of PI heads with them .

Yea just change out the guides but keep the stock chains especially when installing aftermarket cams. I say this because the chains are pretty much stretched out unlike new chains to be broken in and stretching allowing cam altered degreeing. Ford made you good components

Even trucks have the same cam.
