Does a miniram inrease or decreas gas mileage? Any examples are great. Thanks

 

I'd say on a 350 or 355, that mileage my degrade because you have to run such a looser converter and steeper gears as compared to a TPI set up. But, on a 383 or larger displacement engine - I'd venture to say that it wouldn't be any worse than with a TPI set up. I'll post what I get for mileage when I get my car all done. I have a 383 with a Mini Ram, Accel DFI, a 3500 stall, and 3.73 gears.

When I had my LTR set up I was getting 19 mpg or so in town, thats Edelbrock base and runners, SLP cam, and stock heads. When I switched to my current Mini-ram set up (see sig) I now get 15 mpg in town. But I also had a stock converter and 3.23 gears with the LTR set-up.
