I don't think so...........granted they have come a long way since TBI.
Injection is more emissions friendly but it can't hold a candle to
carburetion for raw power and reliability.
Uh-oh it's 4am and your car wont start...............

Thats right, flooded the damn thing again after the "automatic" choke
crapped out again.
With my truck, I just just in and go. dont have to pump the gas, no high
idle, no gasoline smell when I shut it off. Its never too rich or too lean,
dont have to re-adjust it when I go in the mountains. Yes, its very common
to get more low end torque with a carb. As for raw power? Maybe, but not so
in terms or fuel efficientcy. Sure, you need big power to pull that trailer,
but it would be nice to make it there on less then seven tanks of gas.
I will grant you this though, a Carberator is MUCH simpler then a fuel
injection system. However, I have had a carberator somehow vibrate loose on
me and leak gas all over the intake manifold. Not entirely sure how that
On both a TBI & a carb system retorquing the bolts is supposed to be part of
the under-hood matenance procedure.
My 305CUI carb K5 blazer that ran about as well as I'd expect a carb too got
about 14MPH. My 350 CUI TBI F/S Jimmy (blazer) that runs about as well as
I'd expect a stock TBI system too gets about 14MPG.
Apples to oranges - but when purchasing I wanted to get 16-18MPG for the new
truck. Not like I care though!
Suckin' gas 'n' haulin' ass
I don't think that's the posters goal, to make raw horsepower. As well given
a stock motor the TBI system will make more power. Where not talking about
top fuel engines here. It's a 1992 Blazer S-10.
What made more power per cubic inch, a 1979 Turbo Buick Regal or
a 1987 Buick Grand National?
One was carbureted, one had sequential electronic fuel injection.
Since the SEFI engine does not rely on air flow and manifold
distribution to place the correct amount of fuel at the intake
valve, wilder camshaft profiles are able to be utilized for a
given level of driveability.
With EFI, intake manifolds can be designed to accommodate a wider
RPM range where optimal torque can be achieved because among
other things, fuel puddling is no longer a concern.
Emissions is pretty much a moot point because a multitude of sins
can be corrected with a catalytic convertor. But the advantage
does go to fuel injection here for the above reasons plus the
fact that fuel can be shut off completely during deceleration
where a carbureted engine would have had to resort to gulp valves
and such nonsense.
Reliability, even though GM still can't build a fuel injector
worth a damn, they still usually last many miles longer than what
a carbureted engine would go before it needed a carburetor
overhaul/new choke pull-off/float/mixture adjustment/etc.
As for the rest of the electonics, GM cars and trucks have had
electronic ignition since 1975, so beginning 29 years ago, you
were but one shorted output transistor away from tennis shoe mode
The fastest drag cars use fuel injection.
The fastest circle track cars use fuel injection.
The fastest road course cars use fuel injection.
try 73 for HEI!
GM can't build an injector worth a damn?
They use Bosch injectors, or a Bosch style. As does Dodge/Chrysler from
being injected German and also Ford.
Ford never even considered an E-PROM till 97, GM had it in some vehicles as
early as 1989. Dodge/Chrysler I'm not certain of, but I'm sure they used an
E-PROM before Ford did.
