I have wanted these cams for a while , i recently talked to Comp Cams and they said that Ford out sourced 3 different piston company's. So 3 different pistons are in the 96-04, So its a crap shoot knowing if these cams will work! ! .I have heard of people having P.T.V problems, and some not .Yet every time i call or contact A.M they say they will work on a stock motor, with retainers and upgraded springs. I have also researched some say install both cams on 109* intake center line and it will work and some said you degree the cam and it will work. Others say that this cam wont work without noticed pistons, A.M wont take them back if they don't work i'm out of the money for cams and install. ..Anyone have any ideas? i'm running a 01 gt with romeo block.

It seems to me that IF a well known reparable vendor says they will work why don't you believe them?

Regarding installing using a degree wheel it always better to install using a degree wheel.

I'm sure that many of the people that did have problems either:
  • made an error during install
  • installed a PI head onto a non-PI bottom end.

Yeah its a tough call ..when i told A.M that Comp said they are 50/50 on weather it will work they said dont install them..lol ..Ive read where a lot of people are having PTV problems ..and others say no problems with no degree and some say degree. And some say they dont work at all on so confused ..Plus the reparable company says if they dont work they wont take them back..uhhgg..Comp says that ford subcontracted 3 pitons and all have different tolerances ..they said its a crap shoot to weather they will have PTV isssues

In the old days you couldn't leave anything to chance so we used the clay method to make sure, too much money and time to risk. If the heads had been shaved there was thicker head gaskets available as an option to piston switch(yes it would lower CR but it is all about choices). There are other methods nowadays too you can check them out online.

?Have you tried those cams? why do you say you wouldn't even chance it?
I've never heard of anyone installing the 270s on a stock engine without degree'ing it. Plus your 01 model should have the higher compression pistons(less dish).
