newbie and first question....

[98CLLGFND]

So I have a 98 with 4.10's and MAC pro dumps. I have slowly but surely been getting all the parts together to do a PI swap and have begun tearing it down. Im down to TC and crank pully. One question I have is do I need to remove the A/C compressor to get the cover off? According to Chilton and Haynes manual, you dont need to. Also, when I do the cams, does it matter what year I get the cams from? I know that certain years have pressed cam gears and others have their cam gears pressed on. The NPI cams right now have bolted on gears and their is a cam spacer in between the gear and the first cam journal. Im concerned that will the cam sprockets line up with the chains if I use cams with pressed cam gears? Also, when I install the new cams in, if they were bolted on gears, will the timing marks on the new gears be used to install it. I was concerned that the gears timing marks and key way are not in the same position on the new cams as they were on the older cams. Therefore, the timing would be off. I have a feeling this shouldnt be a concern but was just curious. Thanks for the help.

It isn't supposed to matter but I'd play it safe and keep my Windsor (pressed gear) cams with my Windsor ( individual caps ) heads and my Romeo ( bolt on gear ) with my Romeo (ladder caps) heads.

Thats what I was thinking of doing. What year did PI cams come with bolt on cam gears?

 

[tonytaylor85]

99 to Jan 01 was the run of the Windsor engines in the mustang so Feb 01 to the last 04 should be bolt on Romeo cams.

So 01 to 04... I ask because I have some 99 cams and it would be nice to use those and save so money. Has anyone done Windsor heads on a Romeo NPI head?

Comp Cams only list one cam for the 4.6 which is another vote for interchangable.

Yea, I was thinking about going that route or maybe with Trick Flow, but Im like most people and dont have inordinate amount of money coming out my pockets. If I did, Id just take it somewhere, but hey, half the fun is busting your knuckles while working on it yourself.

 

[tonytaylor85]

i was saying that you could use either cam in either head. If Comp had listed one cam for Windsor and another for Romeo then i would say not to mix. But they don't so I say use whatever you find a deal on.

OIC. Im debating about maybe spending the extra money, suck it up, and go with some FRPP PI heads from 50resto.com. If I go with these complete heads set up, Im gonna want the Romeo ones so my valve cover and TC will all bolt right back on and not have to change any bolts to studs or find new valve covers.
