Q: Is the TBI 4.3L a Vortec engine?

A: Main Recommendation is dont touch the TBI 4.3L and if your 1994-95 4.3L has Vortec valve covers that does not make it a vortec engine. GM ran out of valve covers in 1993 and put vortec 4.3L valve covers on both engines.

Q: What to do with a Chevy 4.3 engine?

A: The first (and last) modification that many people make to their 4.3L is to scrap the engine’s stock intake and exhaust hardware for freer-breathing units. First things first: if your engine has fuel injection, then toss your throttle body, computer and intake manifold into the trash and set it on fire.

Q: Can a 4.3L engine work on a 350?

A: This means that practically all tuning tricks and specs that apply to a 350 work on a 4.3L, and a lot of the parts are interchangeable between the two. The first (and last) modification that many people make to their 4.3L is to scrap the engine’s stock intake and exhaust hardware for freer-breathing units.
