I have one at my shop. Bought it a while ago(good deal) with thoughts to retrofit it in my car but changed my mine.(alot of work)
But if you had an intake built and used a Magnetic trigger, Do you think it could make some power??

Just a dumb question here but....Why would you want to put a carb on an LS1??

Why? Why not???

Maybe because you didn't wanna go through the whole process of swapping computers, fuel pump, ect, but you wanted the aluminum block and the crazy new heads they put on 'em. Would make tuning easier too.
I'm sure that you could get a good bit of power out of it with the carb, as opposed to the fuel injection...not sure on how much though.

P.S. I'm sure the intake would be expensive as hell (did you ever get far enough to look into intakes?).

"Why? Why not??? " I can relate to that. Just wondering.

As Mark said, have you priced what a custom intake would cost??

Probably cheaper to get the electronics and go F.I.

No I did'nt. If I get serious about it, I have the machinery and knoledge to do it or at least try it. I'd need to get some flat aluminum stock(or cast aluminum) sit in my garage drink some beers and start doin' some thinking. It can be done, it would be easier for someone else to do, but I don't have the money to do that. What kind of numbers it would put out is what I'm curious about.
Who knows maybe in 5 years there will be a market for a dual carb tunnel ram intake for an LS1.

I dont see why it wouldnt make a lot of power, air and fuel are the same regardless of induction, but it certainly wouldnt run as nicely and get 30mpg. I think street rodders would be a big market....in fact i wouldnt be surprised if edelbrock comes out with an intake in the not so distant future. I know the ASA stock cars ran LS1s this year stock except for the cam and a dry sump...450 hp.

ASA run Fuel Injection?? I thought they're all carbed?
I agree about the street rodders, It would make a great looking engine. With the exhaust ports all even and the aluminum block.
That would be sweet!

absoluletly the asa serie did run a FACTORY ls1...the teams were not allowed to touch the motor, only bolt ons like headers and the iduction system were things that you could change, yes they did have different cams and dry sumps, but as far as i have read, they were gm built motors.... with that cam and dry sump...

and they were also not allowed to modify the prom, each team is given a prom at the track,t he prom is sorta programed for the elevation changes and such... but yeah its pretty cool that they all run the ls1's my bet is the ls6 will be showing up in those in the ener future...

HOGAN intakes can build a custom carb intake 4 the LS1. They r the 1s that built the black tunnel ram 4 the NOS ads. Also, I've read that Lingenfelter had a lot 2 do with the LS1 engines that were 4 the ASA series. I think it was in HOTROD or SuperChevy. My friend has the magazine.

That is because the 4th gen's T56 has a .50 ratio 6th gear. If you strictly use 4th gear (1:1 ratio) on the T56 LS1 and 4th gear on a M2X/T10/T5 carbed engine, you'd get very similar MPGs (if not the same). The only difference from FI and carb is the cold starts and elevation self tuning advantages for FI. Other than that, you are just comparing different manifold designs. And yes, if you know how to tune, it will run just as nicely.

It's nice that you got such a good deal, so you probably can afford to spend a few extra bucks on the carb intake if you want.

However, for anyone building from scratch, I would argue that a factory aluminum block and the broader range of aupplies would make the older SBC-1 design more desirable. The LS1 is pretty much stuck around the 345-360 range, whereas an aluminum SBC-1 or SBC-II can be made to upwards of 420 CID. And we all know how you can smoke 'em at 420... With some extra stroke at a 4.160 bore you can nearky break the 460 inch mark. Some "small" block, huh?

I do believe the LS1 boys dubbed it a "422 Super Stroker" when you get the bores re-sleeved to handle a 4.1xx bore and a bigger stroke... Or...you can resleeve the bores and bore it out to what is dubbed the "All Bore 382 Stroker"... I don't mean to take you away from the thirdgen world here, but i think maybe the ls1.com message boards would be more informative to you... They seem to have the "guru's" of the ls1 world doing some odd engine combinations, and testing various parts, i do believe one person has a carb on his ls1...but i wasn't able to find the post to see where he got it from...
