Hello, I need to know if the engine that has my Blazer is TBI or TBI-Vortec. Thank you

 

well, if you gave us some info on your blazer, like year and such, maybe we vould help ya. Don't know about anyone else, but Im not Psychic.

 

OK, My chevy Blazer 1991 engine V6 4300 TBI.

 

Its a Vortec engine, and you say it has the TBI injection system. So the answer would be yes.

Vortec is a design in the way the air flows through the heads. All S10-Blazers with 4.3 L V6 engines have Vortec heads. The design got better as teh years progressed.
