Anyone tried a carb intake and dist on a ls1?
what he said....
here is a pic of the software and my graph. i use a serial to usb connector and i also updated my software from MSDs website. the cd with the box is outdated. just plot a graph, key the ignition to give it life, save the file to the MSD box, and start the car.
tune carb accordingly and enjoy. i dont run any vacuum advance on mine.

I can see a drop above 5k rpm's to free up some horsepower but that's only on big compression motors. Thats a huge drop of timing at a low RPM range unless he's spraying it from there up?
I found this link on the msd sight.Online pressure units converer.

The MSD box says it uses a 24x reluctor.. i have an L92 which I think is a 58. Do I have to change the wheel or is there a way I can make the MSD work? Sorry.. Im building an L92 with a 750 holley for my 68 Camaro just trying to get all the 2 million variables figured out..

MSD 6012 is the box you will need.

Verdad Gallardo not sure about the fuel injected v carb debate but if i ever went FI i would do it like this guy.

Well with a carburetor your fuel atomizes much better (mixes with air) as the A/F mixture has a longer distance to travel since it is mixed at the top of the intake rather than right before the intake runner in the head. form better IMO. everywhere else the FI will. I would imagine there'd be less camThe fuel on a carb setup actually cools the intake charge since it's only running at 7psi as opposed to the 50+psi of FI which actually heats up the fuel. WOT the carb will per surge and a better idle with a carb setup though as its easier to tune for that.
Now a carb style intake will have a better performance setup as its intake runners are all just about equal length (no #7+8 starvation), they are shorter runners than the EFI manifold, They will stand up to boosted application and nitrous backfires MUCH better, and they look way cooler
. Mines going to have a street scoop mounted to it and sticking out of my hood to give it an old school look since my carb choke horn just about touches my hood as it is.

The carb intake is an open plenum design that seems to have some top end air flow advantages. GM sells an LS2 crate motor in both a fuel injected and carb'd version. With the same cam and exhaust they rate the carb version at 446 HP and the FI at 405. Maybe they used a more agressive tune with the carb, but my guess the difference is more with the manifold more than the carb.
Really it comes down to what you want to do and how well each option fits your situation. They both can be made to perform.

Great discussion here.....so have I read correct, the 6010 box MSD is not the same as the Edelbrock LS1 TCM (that says "by MSD" on it) ?
I want the timing retard functions, and programmable curves so looks like the 6010 is the ticket. Nitrous, blower, all is good.

No issuea at all with my CARB setup and MSD box..
*I did have to go with a different carb... the one is the pictures wasn't so good.
I am running lows 12s @112
