Header length 4.3
Header question 4.3 OBS sierra the motor is an 87 carbed old school 4.3. The headers that came with the engine are different lengths on driver's side(long) than on passenger( short). Anybody ever heard of running one long tube and one short tube? Pros?/cons? Please help me out on this
