Hi Guys n Gals, I have a few questions concerning my 5.0 FL. Most of my ?'s have been answered by reading some old topics, but bouncing from page to page makes me dizzy. #1 the L in FL supposedly means limited, what makes this engine limited? carb, intake, cam, etc...#2 Also read somewhere this is a 302 with 351 cam and crank and maybe heads, anyone know for sure? #3 will swapping intake and carb from 2bl to 4bl do anything for fuel economy? A friend has the same engine the only diff is carb and intake, his mileage is almost double, we can follow each other 30 miles off shore and back, same speed, sea conditions, etc, and it cost me more at the pump. Any insight would be appreciated, Thanks
