do you have to notch the pistons with AFR heads and B303 cam?

[475HP '03 cobra]

any particular reason why?

i mainly like the B cam becuase its real rough and i wouldnt mind sacrificing a little power before giving up that roughness

also i want to have low end torque and the B has more than the F (i know that the E has the most but i dont like that cam at all)


i plan to have steel motor mounts too (i really like the roughness; makes the car fell bad-ass)

well doing more resarch i ca see that the F will make more low end torque....in that case i may consider it but, a few question first so you guys can roccomend me a ford racing cam 3:55 gears, looking for low end power, 5-speed manual, 1992 GT, and it has to fit this combination i have listed in the post: 1.7 roller rockers, AFR 165cc heads


so what would each of you suggest?

I would suggest an aftermarket intake if you don't already have one.

Where do you get your "torque figures" for the B, E, and F-cams? I run a TFS Trick Flow Stage 1 cam and it absolutely friggin' rocks on the bottom. And it pulls at least as high as an F-cam. I mean heck, my car went 12.7 @ 109 with nothing more than heads, Cobra Intake, and that cam.

.

yeah but that is based off cam. My point was that heads are not rated by 'x' duration. Like in his example, he was told that AFR's were rated for a 220 duration cam. The heads do not care about duration. Now ramp speed and lift will make a difference in what valve spring you run but not the duration

naa..naa.. naa..

My car with the b cam went 12.8@108 with a 1.88 60 and it weighs, like 500 lbs more than your car

The Cobra weighs 3600#?

I am just gonna have to weigh mine and dyno it someday.

My coupe ran 12.20s at 111 with the f cam ,out of the box iron gt40s and a typhoon intake. the same cam ran 7.35 at 92 mph in the 1/8th with just a swap to brodix heads and a systemax intake. Its all about the combo. I personally like the f cam. i have made 330rwhp with it n/a and over 600 blown. Its not as good as some but will work good on your car. What intake, headers,inj,mass air etc do you have?
