Cobra Intake w/ F-303 Cam?

UglyFast88 · 03-17-2003, 03:27 PM

Anyone running this combo?

I'm not running to or eliminating the rev limiter, just looking for the best low end and mid range torque.

I'm also thinking about en Edelbrock RPM.

What's the vs. between the Cobra with the F cam and the RPM with the F cam?

Thanks!

The rpm is a midrange and top end type intake. good if you intent to run right to the limiter and even past it. the rpm range is 2500-6500.

you might want to talk with 88 workcar he know speeed density very well and can tell you what cam would be good for what you want.

Thanks-

I'm going to be converting to mass-air, because the 306 I bought has an F-303 cam. I already have the Cobra intake, and was actually thinking about maybe the RPM... Looking for some justification for running the F-303 cam and the Cobra intake. I know the RPM blows past the Cobra, because the Cobra runs out at the top end, but I'm not going to be going up there except at the track anyway, which may be 10 times this summer. I'm more concerned with streeting.

Thanx

uglyfast, you realize your e.t. is the same as mine, did you run that on slicks? how did you get 103 mph though, i got 101.40 with an iced intake, well my next combo will be faster, maybe 106 mph.

I'm not sure. It was about 38 degrees, though. Was the last weekend here last fall.

Maybe it was the cold air plus the Mustang gods. Things just worked out!
