A recently aquired a stock cam. I was told that it was from it wasfrom either 1989 or 1988 H.O. It was pitted really bad,and was unable to be polished.But they did have another one that they had let me have,that was in better condition,almost flawless..We matched them up together,and the lobes along with everything else looked pretty much the same. The only thing that i had noticed was that they had some casting numbers. The one that i had said [ZE],and the other one that i was given said [TE].Can anyone tell me what this may mean?? I was told that the stock 5.0 H.O. cams were similiar from 86-91 and they changed from 92 and up. So if i wanted to get one from a 92 or 93 H.O. for a 90 H.O. engine ,it will not work....Any help would be greatly appreciated...

they will all work,

what is your purpose, maybe i can give you some pointers.

If I were building a trophy stock car, i would run an 88 ish HO cam or i would have one made by AFM

if you want stock specs and maxed out, they will grind it out and still be class legal.

Well Ive got alot of internal head and intake work done. The short block is a rebuild that has not been bored..which is what i was looking for. the only thing my car is speed density..i,m not looking to change to mass air anytime soon...thats whay i needed a stock cam...I,m looking to make some pretty good power on a budget build.....i want an over all improvement of what these engines are really capable of, before i decide to put my kids up for sale to make more power.....Just kidding about my kids,but before i go and spend a Sh-t load of money,I want to see what i can do first.....

I understand about not wanting to spend a ton of money on mass air but its not that expensive to switch the car over. All you need is a stock MAF (I am sure someone on here would give you one), the wiring harness conversion kit (MAWH) is pretty cheap as well, and then all you need to do is scrounge up a PCM or EEC (whatever you want to call it). I would say total investment would be less than $200 and you have a much more flexible engine management system and can get a better cam.

The cam should work, the main reason for not installing an aftermarket cam with speed density is most cams will cause you to loose manifold vacuum. Speed density systems use a MAP sensor to determine load. If you loose manifold vacuum the computer will add fuel thinking the engine is under a load. You should get the same manifold vacuum with any stock H.O. cam. I looked at the specs. The main difference is the intake lobe has 4 degrees more duration on the MAF cars. The MAF cams are are also retarded 2 degrees from the speed density cams. You could degree the cam with the speed density intake center line, 2 degrees is not going to make much difference, but retarding the cam will loose some manifold vacuum. Probably not enough to be a problem. I have hooked vacuum gages to both speed density cars and MAF cars I don't remember any vacuum differences.

what intake are you running? I would pop the cam in and retard it depending on what intake you have. stock e7s?

[thunderchicken]

Stock intake,all runners have been enlarged,aswell as the the throttle body area has been enlarged to 68 mm from 58 mm,and the E7's has had all the intake runners enlarged to match the lower intake manifold that has also had the runners enlarged,and the heads have a stage 2 port. the heads have GT-40 stainless steel valves with 600 lift springs,and the exhaust ports have been enlarged with the humps removed. And they have also been milled 30 thousanths to increase compression...

I totally agree with that,its just that the car has been sitting for a long time and i finally have all the parts that i need to finally get this car running. Mass air conversion will come later when i do more mods including changing the cam
...thank you for the link,it looks like it will be very helpful....

sounds good, just pop some 1.7 rockers on there with that stock cam.

I am thinking about sticking with 1.7's,i also would'nt 1.6's,for now...i had also heard that if i go with 1.72's,with speed density,i may have driveability problems because of the higher lift...there may just be a chance....but i'm working on that at this moment....

[thunderchicken]

Well i finally got the answers that i was looking for,when i posted this thread,The 5.0 H.O. cam that has ZE castings is the H.O. cam,and the the one that i have that has the casting TE Is an explorer cam...If anyboy else knew that,cool...But thats new info for me,and anybody else who has ever been wondering.......
