new hemi mpg in an Abody?

jgale said

Great thread.

I have a '05 5.7L in my garage that will go into my '67 dart. I'll be running a 3.73 rear end, ~27" tire, tko 5 speed ( 1-5 gears are 3.27,1.98,1.34,1.00,0.68 ). I wonder how this compares to my 4300lb. '05 Magnum RT with a 2.82 rear end and 28.5" tire? I average 16.5-18 mpg around the suburbs with it. Freeway trips at 75-80 mph are 22-23 mpg.

2367 RPM at 75 in the 67 dart with what you posted.

If I use the same trans ratio of .68-1 The Magnum rt should be turning
1696 RPM

With the lighter car it should be more MPG but the rpm is higher so I don't know? The dart is set up to be a more performance oriented driver. Should still get great fuel mileage but will be alot more fun to drive than the magnum.:toothy10:
