Hey is there an intake system for an 85 straight 300 motor? I am wanting better MPG, and HP. mainly MPG. What can I do?

 

I am confused by your post

85 DOHC 300?

I assume you mean the 300 6 cyl

its not an OHC, let alon DOHC engine

its a pushrod inline 6

 

Swap a V8. 300's are torque monsters not speed demons.

I am jsut going off what my friend said. I jsut put an air raid on my 99. which BTW I am getting an extra 100+ miles on a tank of gas. appx 5-6 more mpg. Any way He liked mine and and asked what could be done to his. I know that it has 2 air tubes coming from the filter box to 2 different parts of the motor. yes it is a 300 straight 6.

 

5-6 MPG from an intake?

"Thats funny right thar, I dont care who you are"

 

Agreed. No one gets 100+ miles and 5-6 from an intake.
What mileage do you get out of your 4.9?

 

I know PLENTY of people who got 5-6 mpg out of an intake, and here's how you can do it too, in 6 easy steps!

Step One: Mever ever change your air filter, for at least 80,000 miles. Possibly more.

Step Two: Make sure a lot of this driving is through extra dusty conditions.

Step Three: When your filter gets so crapped up full of stuff to where the engine won't hardly run, measure your MPG.

Step Four: Upgrade to an intake system. Add a turbonator for additional benefit.

Step Five: measure your MPG once more and notice appreciable difference.

Step Six: Pat self on back for a job well done.

You're done!

 

I rebuilt the 300 in my 83. Turned out to be a great moor. Used an Offenhouser dual plane intake, a Holley 390 Spreadbore Carb, Mac Headers, and a Crane Cam. Motor pulled strong to 5000, and got better gas mileage than the stock motor. More than a few stock 350 Chevys and 302 Ford trucks were left wondering why they couldn't pull on that funny sounding Ford!

 

and drive like an old lady
