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.

Dead on w/ my 05 Mag RT's mpg.

392STI (A.K.A. 392Stu) is doing a stroked 6.1 w/ MDS in his 68 cuda that is backed up by the viper 6 spd and I don't recall the rear gears.

On paper we think we can get the MDS to function and if so, he may see upper 20's to 30 mpg. We are anxious to get it going and test the theory of the MDS controls we have in mind.

Even w/o the MDS I think it is only a matter of gearing to get these 3200 lb cars to get better mpg than my 4400lb Magnum.

I figure the 1200lb diet will get an A-body into the low 12's if it hooks up.
