What does TBI OHV stand for or mean in reference to engines? And what does SFI DOHC mean. I am talking about two different engines. The TBI OHV is a 93 Buick Roadmaster with a 5.7L V8 and the SFI DOHC is referring to a 2001 Chrysler Sebring Convertable FWD and 2.7L V6.

Throttle Body Injection= Injectors are centrally located in the throttle body. 1, 2 or sometimes 4 feed all cylinders. Your 5.7 has 2. The throttle body is the part that goes where the carb used to go.
Over Head Valve= Valves are in the head, not the block.
Sequential Fuel Injection= Injectors spray in sequence with cylinder intake.
Dual OverHead Cam= Each head has two cams. V engines with DOHC have 4 cams.

TBI is throttle body injection, OHV is overhead valves, DOHC is double overhead cams, I believe SFI means sequential fuel injection, but I am not positive on that one.

OHV- over head valve
