All for .370 lift and under ........

there was a total mileage thread by Hot Rod Dave years ago and he changed / tested many components over the 18 month project ending up around 30 mpg in his 318.
I believe his best mileage came with a specific 273 2 bbl. cam with reasonably high lift but short duration producing high torque at cruise rpm.
Thread was " Hot Rod Dave's 318 Super Duper Mileage Master" .... or something like that.
