Ok guys, I have a question. I am either going to do a supercharger or heads/cam swap this summer. I am wondering how bad the head/cam swap will affect gas mileage. I drive 30 miles each way to work, so I am hoping some of you guys out that that have done a head/cam swap can help me out. Did you notice a significant difference in the gas mileage. I know you have a beefed up motor with heads/cam Code, But you have in between a stage 2 and 3 grind. I am lloking at a stage 1 cam because I know that the stage 2 is no good in my RPM band. Anyone with a stage 1 or maybe 2 cam that can help with input would be great. If you have higher than stage 2 (Code) I still am curious how bad it hurt your gas mileage. Thanks ahead of time.

My gas mileage is around 14mpg.

i get about 23 mpg on the highway.

Damn Code, that is bad. I gues 23 MPG isn't tht bad, that's prolly what I get aboutright now.

What stage cams you got BCisme. What heads, did you get your ported and polished, is so from where. I was looking at Fox Lake Mustangs, Livernois, or VT Engines. Livernois and Fox Lake are each about an hour from my house, so I don't have to worry about shipping.

I don't do too much highway driving. The last time I checked it was around 20mpg highway.

If you do mild cams and headwork, it wont hurt mileage that much.

i have comp XE278AH. the hottest 4.6 2V street cam comp makes without a custom grind. steen racing ported heads. VT engines stage II is a good choice.

like 9-12mpg... lol idk whats wrong with my car. i think since i have a crappy clutch its causing me to lose gas mileage. Throwout bearing is busted, and its slipping a tad....

with the blower you will see an increase in mileage when you are cruising. this is for 6 lb setups. but even then, +1mpg as well as more hp. but it'll probably cost at least 1k more.

the heads/cam definately gets the kewl factor.
