tbi engine top end is different from carb engine top end.
on a carburated engine, the intake and heads use 90 degree angles for intake mounting bolts.
on a tbi engine, the intake and heads use 75 degree angles for intake bolts.
you can choose one of these three options:
entire new engine.
intake manifold designed for tbi heads but utilizes a carb mounting flange on top
or
tbi manifold to spread bore or square bore adapter
For most GM 'trucks' in 85 where sill used a carb in 86 light and some heaver trucks tbi.
no
No, TBI stands for Throttle Body Injection. It is similar to a carb, but uses a different method to dispense fuel.
you can as long as you use your TBI heads if you want to use the vortec heads with TBI you will need a special intake manifold or a carb manifold with a adapter to mount your throttle body to the carb manifold heres some more info TBI heads will mount to the vortec block TBI intake manifold has 12 bolts vortec intake manifold has 8 bolts
thet are infact the same engine. all you have 2 do is eather do away with the tbi set up or change your intake and carb to the tbi intake and tbi
um..........i have NO idea
125 with a carb or TBI, 175 in magnum MPFI form
Yes. It depends on the year. Older engines were carbureted, new engines are TBI.
depends if its fuel injected or carburated. tbi under drivers side door, carb urated should be right by carb
Not enough to notice.
It is fuel injected, TBI / Throttle body injection.
yes you can, but you will have to get you computer re-programmed for the new fuel requirments. It is alot easier to replace the TBI with a carb, then there is no computer to mess with. That's what I did. yes you can, but you will have to get you computer re-programmed for the new fuel requirments.
