whats the best combo yall think for power and gas millage. Im runnin a windsor 302 block with eagle lower end. Stroked out to a 331. Biggest heads trick flow offers in there twisted wedge style. also runnin a lunati voodoo cam 560 duration. trickflow upper and lower intake black powder coat. bbk throttle body. bbk cold air intake. bbk headers. MSD 6 box also MSD Distributer. Summit off road h-pipe with flowmaster super 40s B&M holeshot torque converter . aluminum driveshaft 8.8 rear end with 3.55 gears
but... i only get 6 miles to the gallon lol.. and to top it off i have 175 spray on it and the jets i have for it goes up to a 250 shot the highest i sprayed it was a 200
