Supercharger Cam

[BeauJ]

I've had an E-303 cam for almost a year, and since I installed my supercharger in April, I've wanted to install the cam. Just not enough time on the weekends with work and the gym. I was looking at different camshafts, and read an article saying that the cam for a supercharged engine should have 210-220 degrees of duration on Intake, 220-230 degrees on exhaust, and a recommended 114 lobe separtion. Summit even says under the E cam "Great for use with superchargers."

Anyone have any experience on the 5.0 with an E cam and Centrifrugal S/C, or know anyone? Should I go another route with the cam, or keep it?

Ok an FoMoCo "E" cam is pretty heavy. I built a 300 hp 302 for a Cougar I had and only used a equivalent to a "B" cam. I dont think you'll be happy with the street performance. Plus what have you done to improve the flow of the intake and heads? You can go to SVO online and get the specs for the E cam if you want. If I'm wrong I'm wrong.

put it in it will perform a lot better and sound sick at idle and stuff

Install the cam with some nice 1.6 rr's and a computer tune desgned for it.

Or install the cam with some 1.7 rr's and a 2800-3000 stall T/C and tune the computer fo rit and run a little faster. Another thought would be gears too. another cheaper but less affective alternative to the stall would be a set of 4.10 rear gears. But this is sacrificing some highway gas mileage and driveability. The reason you will need the higher stall T/C is because your powerband it bumped up another 1,000 rpms with the switch from the 1.6 rr's to the 1.7 rr's. Which is fine because you make more power in the upper bands with the centrifugal charger anyways. So as lojng as you make sure to take advantage of it and tune the comp to make the tranny shift at a significantly higher rpm then you will be good to go and really feel the power through the whole band.

If you want to run the E303, then it will be fine. There are much better options out there, but if you have one laying around stick it in the motor and be done with it. If looking for something else, Wolverine, Comp Cams, etc. all make really nice dual pattern blower/nitrous cams which will work better than the Ecam with boost.

Buddy ran an E303 in his stang back in the day when there really wasnt much else for roller windsor motors. It worked fine with a Powerdyne running about 8psi. He ran 1.6 rockers on the intake side and 1.7's on the exhaust to "trick" the cam into thinking it was dual pattern. Sounds redneck, but it worked.

Isnt nothing wrong or redneck about that! It is damn good thinking. I have heard of that same trick used in some comparatively high profile racecars. Definately a good way to accomplish what you want, without forking out the cash for a dual grind cam And I know that most poeple who would want to attempt such a job would probably already have the two different sets of rr's laying around their house anyways.

I'm probably just gonna do the 1.6 and 1.7 mix. I heard the Ecam would add 40 HP at the flywheel, any truth behind it? I've looked at Comp cams, Lunati and Crower cams. The ones they have in dual patterns are pretty big and I'd have to end up gettin a Stall, which I'm not ready for at the moment.

I've got someone in mind to sell the cam to, so anyone have any suggestions?

One thing you got to keep in mind is that the way people mod stangs is not exactly the way you should approach modding your explorer. The reason being is that we have a huge weight disadvantage. And that will need to be thought about when your picking stuff, especially cams. If you dont want to get a stall then go with the 1.6's across the board. If you are willing to sacrifice some power down low then go with the 1.6 INT/ 1.7 EXH RR route. And if your going full 1.7's then have full plans for a higher stall to be going in. If you were going to be running a positive displacement blower then I would reccommend things in a different order. But centrifugal does not make power down low.
