Corvette Engine
I imagine there is a very basic answer however I'm wondering what the difference is.
on page 72 of the 2006 gm performance parts catalog the
LS2 6.0L without ecm and wire harness is listed, showing 400 hp @ 6000 rpm and 400 trq @ 4400 rpm.
on page 74 is the LS 364/440 with identical technical specs. but with 446 hp @ 6200 rpm and 412 trq at 5000 rpm.
at first glance the only difference between the two engines is the ls 364 is a carb. configured engine.
"gm performance parts has taken one of our ls2 engines and added to it a blast from the past - our ls1 4-barrel intake manifold!"
wait, the carb. version makes more power ? what else am i missing or is it possible the ls2 is a little underratted ?

If it's carbureted then it's not exactly same. The intake manifolds are different. The shorter runner of the carbureted manifold allows that engine to breathe better up top. Notice that the carbed motor makes its power a little higher in the power band.
Also cam specs may look the same on paper, but are not the same in reality.

Are you saying two cams machined to the same spec are different? I would have to disagree with that.

Nope, not at all. Just saying that listing the lift, duration and lobe seperation is not the best way to compare two cams. You have to take into acount ramp rates, etc. Those specs may be different.

oh i agree, the intake manifold does make a diff., just shows how much potential this little sb has.

I was reading where they did a comparsion with a carb vs fuel injection on the same engine and the performance was about the same with easier starts with FI but a little better performance with carb at higher rpm. Over all there was not that much difference.

The engines are completely identical exept for the fuel delivery (manifold, carb etc). ALL other internals are the exact same pieces used in the production 6.0. If you want raw horsepower then you use a carb, if you want mileage and emmisions, then you use a fuel injestion system.

imo, i believe one should be able to get just as good or better performance when using fuel injection.
although, it's gonna be difficult to match the airflow characteristics of the carb. manifold. i wonder what type of performance one would get if one was to use a 'carb style' intake manifold with a properly tuned fuel injection system.
i doubt it would fit under the 'stock' hood though. would probably need a scoop.
