    why would you need an electronic gas pedal? Fbody LS1's were just cable actuated throttles..

    and contact these guys..http://www.magnusonproducts.com/ i actually just got a wiring harness from them.. its a roadster harness so its pretty much a stand alone system..

      Ok, i had no idea that the LS1 where cable driven TB. i assumed that since the 99-02 V6 TB where electronic that the V8 was the same way.

      Thanks guys...this has definatly opened up some easier options for the V8 conversion. I has been sweating a V8 conversion since i thought i would have strip out my dash to change wiring. V8 may be in my future yet.

          There's absolutely nothing wrong with a carbed motor.

          Other than most people don't know how to tune them anymore.

          Budgets being equal, a carbed motor will always make more power than a FI motor simply because they're cheaper to build.

          From a legality standpoint, for Michigan, as long as you meet the minimum emission requirements for that vehicle's production year, you're fine. It doesn't matter if you are carbed or not. And it's incredibly easy to do, even if somebody wants to check it.

          FWIW, carbs do nothing to contribute to pollution nor do they have anything to do with having an emissions legal car. That's all about where your timing is set.

          Even if I was in California, as long as I've got a good set of cats and proper fuel system, I could pull up to the front door of the emissions sniffer, pop the hood, retard my timing, go through and pass the sniff test, pull out the exit, pop the hood, reset my timing to where it was, and drive away.

            get an LT1.

            then this:

            then someone with a timing light gun and a brain. dollar per performance, a carb is easier and better. who wants to mess with wires and retuning a computer every time you do a serious modification?

            i think its a splendid idea, and i would do it if i had the money.

              You would pretty much hate yourself when you put a carbed motor in and you can never drive it because youre getting crappy mileage or the carb is out of tune or whatever.

              Plus you'd have to hack your cowl up to put it in.

                Oh boy, here we go again....

                You are right Jeff...there is nothing wrong with carbs.

                LS motors run great when set-up with carbs....they make great power.

                But, if someone where to say buy a "pull-out" motor from a salvage yard that came with everything they needed, harness,pcm, complete intake then it just wouldn't make sense to ditch all that for a carb. You are 95% to being complete, why turn back now only to lose efficiancy and driveabilty.

                  Oh and, don't let anyone talk you into swapping in a LT1 either....it just doesn't make sense anymore to do that swap. The prices on LS1's have come down so much and there are plenty of them around. Sure you can pick up an LT1 for a little cheaper but there is a reason for that....those motors were great in their time but GM superseded them for a reason.

                    if youre dead serious about a swap, there is probably NO reason you shouldn't just find a complete LS1/T56 and make it happen.

                      Yeah, that crossed my mind too...lol...

                      Just depends on what your priorities and needs are.

                      They each have their places.

                      But more power, less complexity, and a cheaper price, carbs are hard to beat for performance options.

                        Be careful of the "more power" comment. FI almost always makes more power under the curve....as well as peak torque.

                          Not for the same money......

                          What's our budget?

                          5000?

                          8000?

                          How about 2000?

                          Let's go build a couple out and compare...

                            Humm...I have $2700 into a 0 mile LS1 crate motor....sure you want to take that challenge?

                            Granted Carbs are cheaper....but like I said before....if you are getting a "take-out" motor from a salvage yard....you already have the stuff you need.

                              I agree with james on this one!!!

                              There is a reason everything is going fuel injected... and dont tell me that a carbed car gets equal emission either...

                              this whole $/hp bet doesnt mean much anymore... espeically with a market flooded with factory PCM's and harnesses and HP Tuners availible for any modifications needed..

                              Carbed guys just dont understand FI so they argue against it..

                                James is that your back up engine or are you going to swap that one in your car when you get it all built up?
