How did your Dodge/Shelby sound?
I have two Dodge Spirit R/T's, 1992 & 1991 with Turbo III engine, 2.2L or
135 cu. in., dohc, 224hp, 1.66 hp/cu. in. ratio (highest of any Chrysler
engine, haven't checked the new Hemi 5.7L in 2003 Dodge Ram Heavy Duty, yet)
141 mph, 5.9 sec. 0 - 60 mph and 28 MPG @ 80 mph.
