Im looking to make a High, low end tourqe motor that gets gets good economy, I herd they go hand and hand. So far i have a 350 sbc I put a new lower then stock cam in it, The enigne has dished pistons. I figured i need 64 cc chambers to get a good 9.1 compression. Now i must figure out the heads. There is a set of completly re-done 93 TBI heads for $160 bucks. I want high tourqe from this motor so are those heads good, or are the fulie heads better. I already got an Edelbroke S-P-2-P intake manifold which is made for econmy and low end tourqe. Can someone give me advice on what i should do, to get low end tourqe engine that gives atleast 20 MPG. Thanks

LOL....sorry had to say this....A LIGHT FOOT.

For low end torque and economy its my understanding that smaller is better.Dual plane intake,cam 204-less intake,small tube headers,heads I would say small intake runners w/ small valves 1.94 and lower like 1.84 or 1.72.

you can actually get alittle better fuel economy with a slightly bigger than stock cam.the less your engine has to work,the more efficient it will be. for example,dual exhaust,electric fan,a 4speed auto tranny wouldn't hurt,a 1 inch spacer plate,and a k&n filter are all agood plan.all tes little things helped my 90 gmc pick-up average 25-26 mpg@ 65 onthe hiway,as well as keep up to any stock 5.3 vortec out there.

Impressive mpg figures, especially for a truck that has all of the aerodynamic qualities of a barn door going thru the air! Anyway, I think Copper top hit the nail on the head with the OD tranny. That will give you to greatest mpg increase. Then you don't have to run pueny valves and a little biddy cam! I love your idea about those TBI heads. I think they are a "secret" part of a recipe that makes for a powerful combo on the cheap. While your at it, why don't your try and install to whole enchalatta and get the TBI set up for your auto. There is a sea of 305 TBIs quietly sitting in the junk yards. I bet you could get every thing you needed, Throttle body and manifold included, for less than 200 bucks! Heck man, get the TBI motor! It's got a roller cam setup. You can re-use those lifters and install a sweet running mid-80s Z-28 cam for very few dollars. That thing will purr and have some impressive power and get good milage. Isn't that what it's all about for the street! Good luck
