hey guys, i was skimming through my summit mag and i saw that edelbrock has a conversion kit to replace the fuel injection with a carb?

im just kinda scratchin' my head at this one........

imput anyone?

jeremy

 

there is a mag out right now (not sure which one) that i saw the other day at the mall... they said its for some rock crawler or something.. the ls1's have amazingly flat torque curves and thats what those rock crawlers need

 

it was in engine masters
winter 2004-volume 7, no.3
i think the only advantage is that its easier to tune in some ways but i dont think theres an advantage

 

LT1's and LS1's work great in rockcrawling rigs (I'm loving my LT1), but the biggest part of the attraction is that they are injected. Few if any rockcrawlers worth their salt would swap the block and heads in, and ditch the injection.

Its for retrofits, for people that don't want to (you can get a long block cheaper than an engine and ECM etc) or are afraid of using FI, or just like the looks of a carb in the engine bay of an older muscle car.

I once saw a 95 GT that some guy ripped the FI out of it and replaced it w/a carb to "make it faster." Idiot Hill Billy....

 

I agree that you'd only want to go that route if you're either A) doing a retro-fit with an LS1, B) unwilling to get your computer tuned (or just completely jaded about carbs vs. fuel injection), or C) running a crazy nitrous setup or something, where you may be exhausting the limits of the fuel injection system, although I think you can push LS1's pretty far even with fuel injectors and computer controls?

 

That's a pretty dumb comment to make. So, you're saying if somebody prefers a carburator over F.I. they're idiot hill billies?

You just insulted every person in Pro-stock, Nascar, Trans am, and just about 3/4 of every racing series out today. Good Job

I'm ditching the F.I. on my 396 project and I'm NOT an "idiot Hill Billy".
Nor am I an old-timer either. I just turned 24.

Did it ever occur to you that maybe the reason why some people might want to switch to carb is because ther are no lines, wires, sensors, connections or that big ugly black box stuffed in the corner - all of which take up space and looks really ugly under the hood of their car's ??. Some people just like the simpleness and cleanliness of a carburator.

It also must not have occured to you that maybe not everyone, can afford to go out and spent major $$$ on an aftermarket set-up like the one from FAST and then have to cough up the $$ for injectors and then even more $$ for computer on top of that just to be able to get the car running. Not to mention all the $$/hour on the dyno to get it finally running right.


I'm not gonna get into which set-up makes more power 'cause there are a lot of close minded people on this site (like yourself) who will argue tooth and nail on how F.I is SOOOOOOOOOOO much better then hill-billy carburators. Quite frankly, I'm not even gonna try to convince you and others like you that carbs are not nearly as bad as you make them out to be and will make every bit as much, if not more HP than your fancy F.I..

My project should be complete by June/July.

It's gonna be a solid roller 396 LT1 putting out 450+ RWHP N/A and in the ballpark of of 650-675 on the bottle. This, in a 3000lb car.

I'd like to see you calling me an idiot hill billy when I'm running a 9 sec. daily driver.

I'll have to post some pictures when all is said and done to show you how it (the motor) will look and perform better than 99% of the F.I. cars on this forum (No offense)

 

there is ZERO chance tha carb can make more hp than EFI. if you think so then tell me how. ive asked every carb that and not one has answered me.

and your gonna daily drive a carbed 396 lt1 with a solid roller cam? ha! i would even daily drive that if it were efi let alone carbed. especially with a 3 speed auto and steep gears.

 

Not sure why you got all worked up. He wasnt calling you an idiot hilbilly. He was referring to the guy who felt that swapping over to a carbed setup would make his car faster.

Your nitroused 396 solid roller weighing 3000lbs will outrun most fuel injected cars on this site, but that has nothing to do with the fact that your setup is carbed. The stock lt1 PCM can easily support 800fwhp with 50lb injectors as long as there are enough cubes (or forced induction) to do that within 7000rpm. This is without any problems with with fuel delivery on idle. People on this site are doing that with the stock pcm.

I think we can all agree that in the end, the decision is based on your application and what you want from the setup. If one switches for the wrong reasons due to lack of knowledge, that person is wasting time and money and are doing somthing... unintelligent.

 

I can't imagine they would. Carbs don't talk

Honestly though, I'm not gonna get into the debate about which is capable of making most power but if you honestly think a carburator cant make as much HP as F.I, you've got a lot to learn.

That's what sepperates the men from the boys. . I guess I have a lot more patience then you do. There were plenty more combinations much wilder than that offered on FACTORY cars back in the 60's and early 70's and people didn't seem to have much trouble driving cars back then now did they? (and those cars didn't even have overdrive tranny's)

It's a 700 R4. It's a 4 speed overdrive. Also, 3.73's aren't very steep.


Listen, if you don't like carbs, that's cool. That's your opinion, but dont make inacurate and false comment's like "there is ZERO chance tha carb can make more hp than EFI" cause that's just silly.

 

The carbed LS1 manifold garnered a lot of attention, because in larger cube applications the LS series intakes have long been the bottleneck to big horsepower (whether real or perceived can be argued). A large single or dual plane carbed set-up would not be.

 

prove it. given the same car, with everything else the same minus induction, assuming both are properly tuned, I'd be willing to bet the FI car will get better mileage and make more power not to mention drivability would be 1000 times better regardless of altitude and temperature, try that with a carb.

You seem to forget that they also have no choice in the matter.

 

I don't need to "prove" a dam thing! Why don't you try and "prove" F.I makes so much more power??

I never once said F.I. sucks. I never once said you couldn't make power with it. I never once said it wasn't as good as a carb. All I said was that a carb can make just as much - maybe even a bit more in a flat out race application then F.I could.

It's everbody else whose jumpin' down my neck with all this "F.I. superiority no matter what" B.S.


What the hell does that have to do with anything?? My point was, if guys who run carbs are "stupid hill billies" as one of the members so elequently put it then that must mean every driver in 99% of all racing series' around the world are all hill billies cause all their cars are carb'd. Give me a break.

Look at my sig. I intend to.

But you know what, when my car is finished this spring, I could come on and say that it runs like a swiss watch and has great throttle response and is every bit as streetable as F.I. but close-minded guys like you STILL won't believe it cause your too set in your ways about F.I. vs. carb to every change your minds. There's no winning with you guys. No amount of proof will ever be good enough. That's okay. When I'm putt'n around town in my 9 sec. street car with it's "crappy stupid hill billy" carburator, You really think I'm gonna give two sh*ts what guys like you say about carbs? Think again. Have yourself a good evening. I'm going to bed.

 

Well obviously there must have been something wrong with all the EFI cars 'cause as we all know, EFI is 10,000,000,000,000 times better than a carb and makes SOOOOOOOO much more power Or better yet, all the EFI cars were sabatoged before the races so that the stupid hill billies and there crappy carbs would win

We all know EFI cant be beat. there's "zero chance" of that ever happening

 

Owned by a typo again...lol. was supposed to be "carb guys".

i never said a carb cant make as much horsepower as EFI does. im saying it cant make more in an equal comparison. it is in my mind impossible. period.

gas in the 60s and EARLY 70s wasnt $2+ a gallon either. thats the point im getting at. that car isnt gonna be street friendly unless youa re goin with a very mild solid roller. then if your gonna do that, why not just stay hyd. roller? they also didnt seem to have much problem driving them because there wasnt much in the way of other options.

some where i thought i read you were goin with a th400 and 4.xx+ gears. ok thats my mistake if not. i wont bad mouth carbs. i think they have a place. i would own a carbed BBC powered chevelle or something of that nature but i think after i fixed whatever other problems the car had, i would switch it to EFI. IMO theres no reason not to.

and i will say it again. until you prove to me HOW (meaning not show me that it can be done) but shoe me HOW a carb can make more hp over EFI in an equal comparison i will keep saying that EFI is superior.
