Re: cam swap

ive heard the E303 is good for sound but... if you want power there are better ways.

I also would not just do a cam, you should do heads/intakes/cam all at the same time so they all match up.

I would wait for heads and intakes as well. You could finish up the bolt ons for now.

Re: cam swap

I believe the e cam requires some additional parts....it's too early in the am for me to list them, the brain isn't working yet.

However, the b303 cam will lope quite a bit and can just be put in as is without rocker issues and what not. I am putting that one in my 5.0 swap while the motor is out as well.

Re: cam swap

B303 IMO sounds better

I had one of these and it sounded awesome.... the E303 is much milder sounding..

If your going for sound!

Re: cam swap

I think you would be much happier with the b303, my 351w has one and when it was in the 1ton duelly it rocked the truck good enough to make the dancing hula girl on the dash dance pretty good LOL. Of corse it had solid motor/tranny mounts

I run the e cam in mine but I have port heads, and comp intake. On cold start it real lumpy. I'm not sure the specs of the lobe lifts but idle hunts from 700rpm to1200rpm until car settles. Also sounds better no cats

Re: cam swap

I am not buying a cam only for the sound of it,but the b303 after researching has the best sound to me as well as the specs i am looking for.Should i have to change anything besides the cam,lifters,gaskets,etc.?Thanks for any input

Re: cam swap

a "b" cam really? it's like the most inefficient cam outa all the alphabet cams (according to the rules in my mind). throw in a "e" cam wit sum 1.7rr if u want lopey stuff wit good output. e cams are i think .498 lift...and when you add 1.7rr it brings your lift to 529. i cant remember wut the duration is. but thats wut i run wit a blower and im pretty happy.

i would advise upgrading your valve springs if your plan'n on a cam swap. and your definatley gonna need a top end gasket kit. the lifters will b fine. you also my consider upgrading your rear end ratio. however, it may not b a big deal if you stay with a "b" cam.

im prolly forget'n sum stuff, but im sure someone else here will tell you wut else you need.

Re: cam swap

my plan is to upgrade to 3.73 gears at the same time as the cam swap,in your honest opinion what would be the best cam(with the lope),for a n/a engine?I am not planning on an expensive head/intake setup,most likely just gt40 stuff.Thats the biggest reason for me wanting the b cam,because i have been told it is one of the easiest/cheapest cam swaps out there.I am really wanting more tourque than hp(i know thats not really what the b cam is for),but they do sound awesome.I will never be able to afford a turbo or sc,so i am just trying to build a stoplight to stoplight car,for the fun of it ,as well as driving it daily if need be.Thanks for any input

if he is think'n bout a blower.. the "e" or even the "b" is better than the "F". if he is stay'n all motor than the "f" is good, but the duration on the "f" makes it not that great fo power adders....that's if he is goin in dat direction. less duration is always better for turbo and s/c. but if your stayn all motor.. i guesse "f" is good. i chose the "e" for duration and still a bit of lopiness. keep n mind that the "b", "e", and "f"..and i believe all the alphabet cams are single pattern cams. which means they all very lopey. some just more than others. the higher up the alphabet you go..generaly the more valve overlap you get (cam lope/ lopiness). they are all good cams. but all work in a slightly differnt powerband. most track guys choose "f" or higher cams cause they make the most power up top in the rpm range. the "e" cam is most popular cause you dont have to be @6250rpm for it to turn on. light to light with a 3.73, i think you would be most happy wit an "e" cam... and not my favorite, but yes a "b" cam. be honest with yourself on how your gonna drive the car, then check out the powerband on the cams.

also, if your goin wit g40/p type heads. dont run more than an e-cam or .498 lift. those heads have smaller cumbustion chambers than stock e7. gt40p heads..an "e" cam, 24lbs inj., 70ml throttlebody, and explorer/cobra intake or better, and a good mass air meter should get you sumwut close to 300hp at the crank.

keep n mind, gt40 heads have larger valves than gt40p, but gt40p flow more because the velocity increased with the smaller valves (gt40p better..on most v8 explorers). the explorer intake is a revised cobra intake, and flow better than factory cobra. you can make decent inexpensive power using all ford components if you do your research. you can get 24lb injectors from 2k and up taurus..and 30lbs. from tbird supercoupe (not turbo coupe). just sum tips if your on a sever budget during these tuff economic times.

i was thinkin that the f303 wouldn't work with the stock setup?it will be stayin with the stock rockers unless i see obvious damage

Re: cam swap

as everyone else stated i'd go with the B cam, its more friendly with the computer and its not too hard on the drivetrain. an E-303 really should have some springs and if your going to go to the trouble i'd get a real cam at that point.

I've had the E btw on two different setups, overrated.

Does AFR and Trickflow not have different degrees which allows you to run a larger cam? I know TF does. I had their street heat kit with a .499 .510 lift 221/225 duration at .050 and didnt have to flycut the pistons.

Yeah, that combo doesn't surprise me as much as if you had said stock..

the AFR stock stuff isn't bad.. though I did snap a few of the rocker studs on mine before I swapped to ARP.

i run .560 comps springs. you should go a bit higher than wut u r planning to run (cam max lift). in case you decide to upgrade cam or rocker arms one day. a lil room to grow is a good thing in regards to springs.

The "B" cam has .480 lift on both I/E. Which is pretty close to what the 93 Cobra was running.Go to your local speed shop or call crane or comp cams they can tell you the springs you need to match the cam. That's your best bet.

If you want good cam advice go to cpg nation and join their forum. Aaron Mick is a tech there and will give you the best off the shelf cam for your application. Tell him exactly what you are doing and he will take care of you. Is this going into a 4.6. If so remember we have piston to valve contact issues so choose wisely or you are going to have to rebuild engine

I would not purchase an a alphabet can personally, their design is from the early nineties. If you want an off the shelf grind, grab something split duration like a trick flow cam. If you ate willing to spend a little, talk to comp or go custom. I would not waste my money on an alphabet cam.
