carbed ls1's
doing a swap and cant decide to go with the fuel injection or a carb setup. Anyone have any expierience with this setup? The car is 98% drag car so gas mileage is no a concern.

I am going to try the carb route just to see how it is. I will use a wide band to try to dial it in. From the published dyno pulls with the carb intake, I realize that a cam swap may be necessary to get the most out of the combo. I will let you know in about a week.

I ran the 6010 msd box and gm intake with a 850 carb on my 402 and was very happy except for the problems i had with the ignition. best pass to date was a 6.19 @ 116. Changing the ignition for next year to the 7al box a crank trigger and msd's cam sensor.

What kind of problems with the ignition? Box go bad?Also are you using a LS1 style convertor in your 700r4 or a hughes adapter and older style?

From what I have seen for a mostly dragrace application, a carbed LS1 will make more power and get down the track quicker. I am sure MPG will suffer some from a carb over efi, but as you said that is not a concern.
I am in the process of putting a heads/cam 346ci carbed LS1 in my 2nd gen 1970 Firebird. I look forward to seeing what the results are!

On edelbrocks website it says that msd makes the ignition box for them in this setup... Where can i find the msd ignition for this setup? Is it just a direct replacement of the old one or how does it work?

the advantage using the newer MSD box is that you can laptop your ignition curve and like TJ said, it has a two step in it as well. The older MSD/Edelbrock has chip you plug in to the side that set the curves for you. It's just not quite as easy to do a custom curve on. Hey TJ, that old "edeljunk" sure seems to make your car run well. You wanna borrow my TH350 until you get yours back together?? You're welcome to anything I have here at the house........

I have a CARBED C3
First C3 to have a Carb LS1 that I know about...
Works good.... runs Good...
I have a comp 224 cam, corvette manifolds, 3000 hughes stall on a TH350 with 3.36 gears running a 680 AED holley DP
Plan to upgrade to new MSD box and put my plate system back on it
but still working out C3 eletrical issues...and need to get my L88 hood put on.

Well i actually had a th350 in my car last year. I ended up changing my setup when i was putting the car together. i couldnt find a 700 that would stand up to the hp and tq. that i was producing. I just had problems with starting the car when i got it all together. Never found the problem but it just decided to start one day after i got back from out of town.
