Camshaft?
Guys I know there alot better cams out there for my mass aired 92 F-150 302 motor, but I was given a E303 camshaft for free and it's brand new and still in the ford racing box... Would this cam be any better than the 5.0HO camshaft I am currently running now?
Thanks,
Jason

that is a good question. it realy depends on your truck and what you intend to do with it. that is a roller cam, so you will need roller lifters. plus you will need different valve springs to match the E303 cam. what gearing do you have? that cam is going to change your power band (2200-5500rpm) so to retain low end torque you will need 4.10 gearing or more. what tranny do you have? you might even need a stall converter with alittle more stall. the E303 is a good emissions legal cam..... in a mustang. oh and another thing. the stock truck intake and exhaust systems are way different than that of a stock mustang. you might be beter off selling that cam and getting one that is a step up from your HO cam, and there are tons of them out there.

not trying to cause trouble but how could the torque curve be the same with both cams? the E cam has a 110lsa and 220 int, exh duration. is that simulare to the specs of the HO cam? i could see the E cam making the same torque higher in the rpm range but that would come at a loss in the low end wouldnt it??

right yes 282 advertised duration. i was speaking of duration at .050. isnt this the more accurate way of finding out torque and hp from a desktop dyno? once again not trying to be a pain just to learn!

Okay, my truck is mass aired, with 4.10 gears all the way around in my 4x4 92 F-150... I got the gears just wondering if the cam would be worth putting in over my HO camshaft that is already advanced 4*....? I am running 1.7 crane roller rockers that came stock on the cobra GT40's and with those rockers I would be pushing the .529 on the intake and exhaust valve lift.... I would definitely have to upgrade the valve springs, so in order for me to go through all the labor of putting this cam in, would it be beneficial at all from a performance standpoint. Truck is basically just a toy anyways to me....

Well, if that desktop dyno is right, the question is "Is it worth it to YOU"? Is a cam swap worth no torque gains and 20 horsepower? Any gains are worth it, but the labor comes into play. So, it just depends on how much you mind swapping cams. BUT, if you are looking for more performance from a cam, maybe you should look around a little more first.
Like mentioned earlier, you could always sell that cam and get one more suitable for a truck. But, you do have 4.10's, so that widens the options. Is this truck planned to be a speed demon or a stump puller/off roader?

Well if you look at that spec it's the same story, the HO cam is 211 degrees while the E cam has 220 degrees. It really doesn't matter what spec we look at, the software uses all of them so the outcome won't change.

That really depends what you want from a cam change, if it's a bit more HP then it may be worth it, if it's more TQ then you're wasting your time. I think there are better cams out there, cam that will give a broader powerband overall, maybe talk to a cam manufacturer to see what they suggest to get the most from your motor.

im using the trickflow stage1 ( simulare to the E cam ) cam in my 302 bronco with heads intake gears and a 5speed and just from my experiance it is a blast to drive but your main seat of the pants power doesnt start till 3000-3500rpm and it pulls to 6000rpm. if i would have done it all over id get a cam that offers alittle more low end power. remember that cam was made for a light veh.
thank you conanski for the banter back and fourth. im using the desktopdyno2000, yes its outdated by todays standards. in the cam math it allows a person to enter cam specs in at .050 or as advertised duration specs. and with my desktopdyno it gives different power numbers depending on what specs you use. i use .050 specs cause thats what comp cams said would be more accurate.
