Lsx 376?

[blackenedheart]

Just curious because I have been an onlooker here for a while. The 376 looks like a nice addition to the GM line... Would this be an option in a GTM?

Also, are CARBS a sin on a super car?

Carbs are definitly not a sin, some webers would look cool.

I've been thinking about a carb for my car, and I think it would be much easier to tune and possibly make more power if done properly.

The only difficulty is making a decent sized intake manifold and having it flow properly with the air/fuel charge rather than injected down the
runner.

Also need to have rear-view capability.

Wait a second, cooler looking is a definite, but more power? Is that actually possible?

Not only possible, it has been done (over OEM EFI systems). Carbs meter fuel in real time via mother nature. No PCM /sensor lag, no mapping
to worry about.

EFI is certainly more versatile, and more fuel efficient though. It's a close comparison if you can setup the idle/transisition and main
circuits properly. I think the biggest downfall of the carb setup is the constant need for adjustment for atmospheric changes.

A good aftermarket EFI system can address these points very well but there is added cost involved. Mind you, a good performance carb
is not cheap either.

It's been a long time coming that the EFI systems could rival the carb. Heck look at all the time and money that went into carb development.

For quite some time now the EFI has been known to fatten the torque curve and really improve the low and mid range power. Do they both peak out about the same? Yeah, but given the fatter torque curve, better fuel economy, and increased safety of EFI, at this point in time and evolution, I really don't know why you would go to a carb.

ITB setups, whether EFI or real carb, like the Weber, are a NIGHTMARE to keep tuned properly. They certainly look really cool, and the EFI is certainly tons easier to keep correct, but a shared plenum intake design is much easier to keep running at near maximum efficiency.

I would have to agree with Crash on this one. There are very good reasons why you have not been able to buy a production car or truck with a carb on it for over 20 years. To me, it's like suggesting also going back to a distributor with points to go along with the carb. EFI does not go out of tune.....ever! If it doesn't run right, it means that a sensor has stopped working or something is mechanically broken or wrong with the engine. If you stick with the straight-up EFI crate engine (like the LS376), and buy the ECU to match, there should be no tuning needed anyway. It should be a plug & play.
