Hi all,
First post and first long trip in my '23 Track-T. A little disappointed in the fuel mileage but with the cam profile and duration I guess it is OK. Running a 355 Chevy, Holley double pumper mechanical secondaries 600 cfm with a m20 4 speed. 3.54 Jag IRS. Driving at 60 mph up highway 395 to Tahoe got 13 to 14 mpg running 2250 rpms. Comp cam XE274 H-10 110 degrees cam lobe seperation, lift .327 to a 1.52 ratio roller rocker and 286 degrees duration. Car is 1790 lbs. Can any kind soul shed some light as to this mileage with this setup? I'm considering going to a Rochchester Q-Jet carb for better mileage.
