Cams in GT40Ps
Im about to toss a 97 Explorer engine in my truck. I found that the explorer camshaft is a peice of crap(exhaust lift the same as an HO cam, but intake lift is like .040 less).
Im thinkin of putting in a FMS cam, either an E or an X. I dont want to change valves, and stuff, but if I need to change springs thats fine.
What springs/retainers/locks would be recommended for these cams?

thanks for the responses, but did yall leave the original valves in there or change them?
I dont want to get into changing out valves. If I can get a drop in retainer/spring combo, that would be great.
I plan on using 1 5/8 shorties, 2.5" exhuast, the explorer engine(inlcuding intake, injectors etc), explorer ECU, SCT XCalibrator, Pro M 77 MAF, and its going to be hooked to the 4R70W thats already in the truck.

you can use stock valves with no problems,and you could use the stock springs if you don't go over 500 lift cam.but for the cost of the spring kit i would do it so you don't have to worry about valves floating.i have the comp cam kit on both sets of my heads,never had any problems.they 110 pounds of seat pressure,and capable off 542 lift.hope this helps.

i highly doubt that x will clear, never heard of someone usin it on a stock shortblock before, I used a tfs1 cam in mine, made 270/320 with bone stock heads, crane springs.

x cam will work on a stock bottom end with the stock heads that have been shaved.460tzille ran a x cam on ported e7 with trickflow valve springs on his old car.they say in the ford books that the stock pistons can handle a 544 lift with a 184 intake valve.but is allways good to double check your piston to valve clearence.i would stick with the e cam my self for that combo you are going to run.i am running a e cam with 1.7 rockers on my stock bottom end ho motor, with my ported e7 heads,that equals to a 532 lift.
