arent carbs bad for throttle response??
just wondering

Not at all. Although an extreme example (and not an autocross application), have you ever seen the throttle response of an NHRA Pro Stock?

EFI is very convenient, but carburetors are a great method of fuel delivery; the problem is that many people write them off because they don't want to/don't know how to tune them.

my motor is extremely snappy, in fact I'd say it responds faster than any EFI that came stock on a thirdgen.

They've got to be tuned right, but when they're right you woudlnt know the difference between them and a fuel injected car just by driving it.

Race cars have been using carburetors for a LONG time before EFI was around and some still do use carbs.

hmm...interesting :P think my impala needs a carb rebuild

ask the NASCAR guys how snappy throttle response is.

mine is pretty snappy too, but i'm a drag racer

It could just as rightly be said that many people write off EFI because they don't want to/don't know how to tune them.

I agree with that statement 100%... Think that is more so than a carb.. I like and use em both.... May sometime throw a carb on my squarebore VR efi just to see the comparison.

I agree, there is no doubt that tuning EFI can be involved. I suppose I was basing my opinion on my own experience- I'm 26 and most of my friends around my age don't have the slightest idea as to how a carburetor works, but they can really work some magic with a laptop and the appropriate software for their application (evotune, K Pro, etc). When it comes to something with a carburetor on it, they are scared to death of it.

The principals are the same. Why be afraid of it?

I started on carb cars, went to EFI cars, then went back to carb cars. Now I'm back to EFI and I'm doing an MS2 on the new build.

Either can be tuned to work well, and either can be screwed up by a moron who will then complain that it is a "bad" setup.

just to be clear..there still very responsive? (carbs) when tuned right if im understanding correctly? im not considering changing the GTA over, i was just curious

If you drove mine (As long as it was warm) you wouldn't be able to tell the difference between it and an EFI setup at all as far as drivability OR throttle response. You jab the gas at cruise and it takes off. Before I had it tuned up right it would surge all the time at various RPMs and it would always stutter and bog when I jabbed the gas, whether in neutral or rolling down the road. It just takes a little playing around with things to get it right, just like EFI.

Biggest difference is my car has a wonderful fuel smell that emanates from the carb.

Other reason for carbs is rules. In the class I run in autocross(CP) Aftermarket fuel injection wasen't legal until last year. Getting the HP required to be competitive through a restrictive stock TBI or TPI just wasen't going to happen. I suspect that since aftermarket FI is now legal in CP more cars will go to it but there really isen't anything wrong with a properly set up Holley Double pumper.

Are you doing this to the car in your information at the left? 3800 series 2? Do you have a build thread or swap thread that you did?

Very interested because I am gathering parts for the Buick V6 swap right now. I am pretty sure I am gonna run port f.i. but you never know when someone else has already done it.

I'd especially like to know if you have run this car in auto-x, and how it did. I am also gathering up suspension parts and I am really curious what you are using.
