4.3 Vortech

[MadMac56]

Anybody know what type of injection is on the 4.3 Vortech???

TBI? CPI? None of the above?

Depends what is on the top of your engine, they came with 2 types of injection systems. TBI looks simular to a carb, but has 2 large injectors sitting over top of 2 butterfly valves. The Port injection will have actual fuel rail with individual injectors going to each cylinder.

OR it could be CPI inside the plenum, he never stated the year.

OOOPs...it's a '96

It would be a CSFI(Central Sequential Fuel Injection)
