It was in the 10's on the show, its been 9.57 in the high 130's since.

There you go again. Thinking you know something about somebody you know nothing about. What is the point of makiing asssumtion that people are unable to do something you did. I am sure if you are able to do it, It couldn't be too hard!!! There is an assumtion for ya!!!

Fuel injection ftw... no stuck floats or bad power valves. I can crank my shit up in cold weather and walk away while you sit there and pat the gas trying to warm your junk up.

[BigdaddyDupree]

personal preference. i prefer to not bitch about the subject. ill just run my junkyard carb 5.3.

[Harry]

I have no cold start issues with my carb setup. If it is setup right you don't issues with it.

[Illusions]

I don't know what the big deal is with some but all I will say is you run what you want and I'll run what we want. unless you want to foot the bill to convert mine to carb and then I will have times for FI and Carb and we will have the comparison. if not then opinions are like ***holes we all have one.

Have a nice day.. You too Harry!

Wiring harness isn't heavy, the little plastic sensors aren't heavy. Where's all the weight. A carburetor weighs more than a throttle body. That would make up for any added weight of the sensors and harness.

there are so many magazine articles paid for by FI companies and still the poor magazines cant even fudge the numbers enough to make FI look good.

In a boost application though, FI wins hands down and is much easier.

Obviously you didn't comprehend what I was saying. So I will repeat myself no more.

I wouldnt agree with that 100% either. I have done both and drivability tuning if far more difficult with FI than a carb. Just my $0.02 worth.

the differences in what a carb needs to have to be a blowthru makes taking your run of the mill ebay carb and making it a blow thru basically a no go for your average tuner.

A fuel injected setup tuned properly will run better than a carb setup. With a computer you have way more adjustabilty vs a carb. Just on a stock ls pcm the car uses 15+ timing tables and adjusts for everything from a/f ratio, intake air temp, coolant temp plus more and thats just on timing. It does the same thing for fuel tables. Plus the pcm is always using feedback from sensors to adjust and correct for conditions. With a carb you can get it to run and drive really well but it cant constantly make changes on the fly to run perfect. Yes fuel injection is harder to setup, you also have to have someone tune it and you always need a laptop for changes but dollar for dollar you cant beat fuel injection. Once you go fuel injected you wont want to even own a carb.

just bought a turn-key 4.6 DOHC with harness out of a 98' Lincoln Mark VIII

aluminum block cast in Italy by the Fiat subsidiary Teksid, is to me the best damn 4.6 block there is

Considering a Sullivan intake and LT headers with no power adder, suggestions?? Engine only puts out 280hp/ 285lbs
Maybe a 4L60 trans to back it up.

i agree with everything you said but a carb will make more power. air and fuel mixing in a plenum atomizes the A/F far better then an injector does 2 inches from the chamber

I would have to see it to believe it. I would bet on the fi making more power because you have more fine control over the fueling. My current motor is basically a carb setup with fuel injectors since Im running a single plane intake with a accufab tb. I can't see making more power just by getting rid of my injectors and going to a carb. If you have both motors at the same a/f ratio and timing I would think the fi would make more over carb because of the injectors spraying into each cylinder.

should have went ls based if you wanted more power

yep, i would think so too but it doesnt seem to work out that way. I'm not an anti-FI guy. i just wanted to point out the pros of a carb system. just like others wanted to point out the cons

So it will crank up and idle in cold weather without you having to sit there and pat the gas

No it isn't exactly like FI. You do have to pat the gas once to get some fuel in there. But, after that no I don't have to set there and pat the gas. No where near as advanced as that there Fuel Injection stuff though. Also not near as complicated either.

It's still cheaper than a complete FI system making the same power. Mass air meter, throttle body, computer that has MAP feedback is a lot more expensive than a $700 carb. Plus an average tuner will be in the dark trying to tune the FI. The carb system tunes just like a regular N/A motor.

I like both myself, in diffrent setups.

If I had a ford pcm I would go carb'd too.
