I'm putting a 87 5.0 motor in my 66 fastback. It has a C4 trans with a 2.8 rear. This what I thought I would do to the motor. Tri-y headers, probably the preformer intake or the air gap intake, 600 carb. What cam would you use? Ford racing preformance has 2 cams that I was looking at. The "B" .480 lift 5100 rpm or the "E" .498 lift 5500 rpm. Thanks for the input.

the question is wut kind of power output do u want if u want more power and a rougher idle id choose the second one but if u want a smoother idle with less power choose the first its all about personal preference

I would to like to get more power out of stock motor and let keep the driveability of a street car. I'm not interested in racing on the drag strip. I just want to make sure as a complete package that this combo will work. Hope that helps. Thanks

Stock cam is a good cam it just needs better heads. But it is kinda an old school type, like the B303, E303 etc. the 303 type cams work with the stock computer but there are better ones out there.

We never found much difference between them with stock heads, except for the X303. We had the smallest Extreme Energy cam in one with stock heads and it worked real well. Even picked up some mpg with the stock gearing, made a bit more torque in the cruise rpm range.

Instead of a cam swap, I would do a head swap on it, yes it costs more but you can pick up more driveability, detonation resistance and some power with a head swap. I have read really ood things about the AFR series, and next year I will try them on my F150 with the 347 thats being built for it. TFS worked real well on the 5.0s we built in the late 90s.. just some different ideas to think about.

Since your are running a carb, a custom grind from Comp might be a better choice. You could get a 110 or 112 lobe centers, more duration on the exhaust and eliminate the need for a steel gear on your distributor.
I had this one made: FW 3341 / 3342 HR110.0
It pulls hard up to around 5200 rpm then starts to drop off.

you should go check out the 5.0 area, they have tons of responses to questions just like this. From what I remember those guys saying, the FRPP A, B, E, X cams are actually outdated and usually they will then recommend that you go with the Trick Flow Stage 1 cam. Im not sure of the grind specs of this particular cam, but most of the guys recommend the TF one over any of the FRPP cams, especially for an application like your describing.

Just FYI, anything above .480 and below .500 or so will give you better top end performance without the loss of driveability (you'll get a good lopey idle and more torque above 2500rpm). I am running a .500 lift crane energizer cam and it has a killer idle tone and pulls hard from about 2500 to 5500.

Also keep in mind that with the higher pulling cams, you also experience a little loss in low end torque (more noticeable if you are still running the 2.73 freeway gears....not as bad if you jump up to a ratio that gets you up through the rpms quicker).
