i found out from the dealership the secondary's are not hooked up on the Rochester 4bbl i averaged 11.2 mpg on the interstate going 65 mph i went 35 miles.
but i got to wonder what kind of rear end it has really revs high taking off from a start. when i got on the interstate it looked like Moses parting the red sea they cant stand my loud cherry bomb exhaust its true dual 3 inch with 12' cherry's on it.
i just got home with it im going to fix a few issue like rip out that plastic bed liner and put a dash pad on it but other than that its done.
