Hello from Mississippi
 

I've got a Hotrod Camaro SS and I stumbled accross this gassavers.org in search of improving my fuel economy. Already, I will exchange my present cam a 228/230 112lsa with huge lift to a more down to earth 214/220 cam with a 116 +2 LSA custom designed cam to produce both power and fuel economy. Additionally, I have a fidanza aluminum flywheel that will reduce some rotating mass in the drive train. I'm also hoping to use some of your aero tricks to help the ole MPG.

Sweet ride. I love big cam small blocks. Any videos?

I had to dig a little but here is a video of the car.

swapping out to different gears will help more than the cam swap. And find some eagle GS-C tires that came stock on the car, they are about the best low rolling resistance tires you can find for the sizes on these cars.

Mine has a 110 degree asa cam, 3000 stall 4spd auto, 2.73 gears and I still get 24mpg. when stock I got 28mpg normally.

Just using the skip shift that came with the car and trying to keep the car smooth and easy should get you over 20-25mpg without much effort as long as the gearing isn't making it rev high on the highway. 1500-1800@65mph is what mine does if I can remember it right.

Thanks Coyote! I already bought the cam and the flywheel...so I'll install them. I still have my 3.42 gears and I will see what kind of improvements I can get before going back to them. But I need to get a base line first.
