what would the gas mielage be like with stage 2 heads and cam??

 

I still get 22-24 mpg on the highway. Around town depends on the right foot. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Hmmm 22-24mpg, pretty good for 4.10's. When you made the switch did you notice a big change in gas milage.

You've got to remember with a M6 I'm only turning about 1900 rpm @ 70 mph. Drove to the OC car cruise last October, its about 150 miles from my house. Then cruised the beach doing some spirited driving, stop and go, got 19.7 mpg. Last time I drove the car to work for a week, all highway, got 22.7 mpg. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> That's one of the things I love about these cars. How many old shool muscle cars can run low 11's and get 23 mpg. Answer 0.

I drive my HC car from Dallas (Home) To Indy (School). So far, each average has been ~ 26-28. I get about 280miles to a tank. I can make it in 3.5 stops. Total distance is ~ 915 miles door to door.

417/410, 4.10s, and a 6 speed!

Well I have a 98 SS 6 Speed and whhen i first got the car i was getting about 250 miles to the tank. Now I'm getting 200 when i hit empty. The car is stock. Any comments? Thanks.

 

I get about 200 miles per tank... hmmm... stock motor, yes I have a heavy foot <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> So long as I get above 10 miles/gallon w/my new heads/cam package I'll be happy <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Right now, stock, with pretty much all stop-and-go L.A. traffic, I get around 13-15 MPG. I hit 19 last week when I was doing about 75% freeway. This sounds like it's on the low side compared to most people here. I hate to see my gas mileage when I put in the 427 <img border="0" alt="[cry]" title="" src="graemlins/gr_cry.gif" /> Oh well, if I wanted great gas mileage, I would have bought a Prius!

 

My car isn't as aerodynamic as an F-body but I still got 24 mpg cruising 70-75mph on the highway in 6th gear with my 4.10's <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Before heads & cam w/stock gears Typical 320 to 340 miles per tank and 23.5 to 24.5 mpg average. Best highway 32.8mpg

After heads & cam + 4.10's Mileage per tank varies wildly, depending on how I drive. I drive the car harder than before. 250 to 275 miles per tank roughly. 19 to 21 mpg average. No long highway trips yet. Best highway 25 mpg on a fairly short trip.

My car always gets worse mpg <img border="0" alt="[chug]" title="" src="graemlins/gr_chug.gif" /> in the winter. I let the car warm up more than before because I don't want to risk a valve spring. I also get on it a lot more and mpg has dropped - a lot.

As someone else said, 418rwhp & 404rwhp + 4.10's and 20+ mpg so I can't complain at all. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

My 99 LS1 gets 32 on the hiway, 19 in the city with a little hotdoggin once in a while. I had a 69 camaro with a 396(402) 375hp big block with 410 gears that got about 6-10 mph. it had a 15 gallon tank and I could actually see the gas guage move between traffic lights if I was getting on it a little. I love the perfomance of these engines, and wish I could go head to head with my old camaro at the race track to see what differnce there would be.

When I went up to the TR Shootout I rec'd 26mpg with my 4.10's..

 

When the car was new and stock I got 20 to 22...With all the mods I now get 8 to 12 in the city and 2 to 4 at the track shooting nitrous.
