The X cam's lift is likely a problem with the stock roller springs. Don't count on it working without a spring change. It's also going to stress the stock pedestal rockers and bolts. At a minimum, you'll need to swap to roller rockers, and then you may break a few of those 5/16" pedestal bolts. The B & E cams will work with pedestal rockers, even with 1.7's.
I think all the hood latches are the same. PM me and we can work out shipping etc. There are headers out there that work with the P heads AND fit in a maverick, if you want to spend the money. I think they were in the $400 range. Those pics are Hooker 6901, and I would guess the Hedmans would fit the same way.
I am currently finishing up a complete 5L motor based on a 2001 Explorer long block. The cam being used is a 95 Cobra. Heads have some carefull port work because the flow can be lost with a wild job. Change the front cover, damper, water pump, use the correct pan, oil pickup and flywheel with the trans being used. The EXP motor is dressed with parts you can't normally use. These motors should be fairly cheap as they don't drop into the early cars without changing the dress. Finding one from a wreck with low mileage and the right price makes a heck of a motor with dress parts from an early motor. You have a choice of using the stock Exp cam which will give you very good low to mid range power, use a stock Mustang, Cobra or some other cam to your liking. The P heads compaired to E7 heads begin to show their airflow worth from about 3500 rpm upward. My headers are FMS p51 but going into a later 90s car so the header issue is not a problem for me. The point is there are some good motors out there to use as long as the outside parts are swapped with the older parts. The gaskets for the later motors are even so improved over the older motors if you considereing ordering the pan, intake and the valve cover gaskets with steel in rubber. The pan has seperate steel outer rails. Look into this as an alternitive to doing an old motor over.
if i do get the e303 or x303, are there certain size springs lifters and rockers or will any from ford racing work?
This may seem dumb, but how do you know which heads you have? The 302 I'm rebuilding is from an 84-85 Econoline. Both heads' spark plugs come out at the same angle, roughly 50-55 degrees (just guessing).
40 P heads are IDed all over both inside and out as well as the plug angle. They have 4 bars in each end. The 40s have 3 bars on each end and have plug angle the same as all the other older heads..
You need springs to match for the X cam, the E cam will work with the stock GT/HO roller springs. Thrust plate is the same for all. Just make sure youy don't use the FMS timing set with the steel cam gear, then you WILL need to change the thrust plate.
thanks, what about the lifters rockers and pushrods, and will all of this fit under the valve covers?
You can use the stock rollers, but Crane's replacements are better. Pushrods--you need new ones if the old pushrods are worn at the rocker ends, they don't spin like flat tappet rods and wear to a knife edge at the rocker. Clearance with roller rockers usually requires tweaking the oil baffles or sometimes taller covers
ok what do you mean by tweaking the oil baffles and where can i get taller covers and how much taller. are there any cover spacers i could use?
Tweaking = LFH, not BFH. In using them with the 82-85 GT Stang finned aluminum covers, the oil baffle under the filler hole was the only contact point with the rockers, and even then all that was needed was to dimple (tweak) the baffle to gain clearance. Downside to that on those covers was it usually loosens the baffle rivets. Some covers work as is, some don't. The 93 Cobra 5.0 covers are short stamped steel covers but they cleared the 1.7 pedestal roller rockers they came with.
oh ok so some covers will work and if they dont you just kinda hit it to dimple it? i thought that the bigger cams would raise the rockers higher and too high for the covers.
