Post Knowledge base question about Isky cam?

About 20 years ago Isky made a "Mile or more" cam. Anyone know the spec`s on this cam`s profile? What made it a gas saver? Did it dump off power for fuel savings? No project just want to know. Thanks!!!

I remember the cam you're talking about. I also think it was a little longer than 20 years ago. Mid 70's when Holley had the Economaster line, and Edelbrock did the S.P.2-P. series intakes. I don't remember exact specs but I do seem to recall one of the mags doing a build using one. I'm thinking it had a real long intake duration and short exhaust. Almost no overlap. Was to be used with 11-1 compression or so. I think they made stock horsepower numbers and 30mpg in a 350. I'll look around in some of the old stuff I have and see if I can't come up with something.

Dan, I think the cams you are referring to were marketed by Crower in the 1970's. Can't remember what they called the series, but they sold it as a complete package, with pistons. The pistons were very high compression and as you stated they juggled the cam timing around to arrive at a reasonable DCR. Have heard reports that gas mileage was excellent as long as the vehicle was unloaded and travelling on level roads. With a load or steep grades the vehicle barely had enough power to make it to the top of a hill. Good theory, but didn't work in the real world. Crower dropped this series of cams after a very short time.
I think Slider is referring to the old Isky Mile-A-More cam line which was basically an RV or gas mileage cam. Never used one myself, but Isky is known for quality stuff.

engineguy,
You're probably right. There have been so many different, catchy gizmos over the years that they are hard to keep track of. Thing is, you see "New" ideas every day that where tried 20+ years ago, that didn't work then. You would screw it in the fuel line, or it would boost your coil output for super gains in horsepower and fuel mileage. After you try the "Trick of the day" a few times you tend to find that the only thing gained was a lighter wallet. Dan

Dan, you are absolutely right. The gizmos seem to come and go in a regular cycle. Evidently the snake oil salesmen fiqure that there is a new and younger market available about every twenty years. The old magnet on the fuel line, screen in the intake under the carb base to "break-up" the fuel, this stuff comes back on a regular basis. I owned a Texaco service station in Arizona several years ago and had several people come in trying to sell me a line of remote oil filters that used a roll of toilet paper as the filter media!! They claimed that you change the roll of toilet paper every 10,000 miles or so and add one quart of oil! You NEVER had to change the oil! Jeeez, give me a break. Wonder what ever happened to those things?
By the way, I am not saying that the Crower cam/piston deal was snake oil. It was a concept that worked very well in theory and probably had excellent results on the dyno. Problem was, it just didn't work that well in the real world. Crower is a very technically-oriented company and they make very good products.
