fuel injected or carbureted

[mustangkid]

I have a 1991 lx fuel injected 5.0 and I am thinking of going carbureted. I could use any thoughts or opinions on this idea. Thanks:dunno:

What are your plans for the car?

[mustangkid]

bore it .030 over, 347 stroker kit,150 shot

I have a $3,700 build that i want to start on next spring. At least as of now thats how what my shoping list has on it.

If the car is going to be more race than street...go carb. Generally everything else being equal, a carb makes a little more hp. If you plan on driving the car on the street a lot...go FI. Either one can be made fast at the track or drivable on the street.

Jeff88coupe has a very fast fuel injected 347.

This will be a little more track than street.

I did a carb conversion on my 91 lx and love it, let me know if you have any questions if you do the swap

The carb route seems to be cheaper, but the FI route is much more flexible...

[theyallslow]

thats all up to you. if you spend your money right they will both work great, but carbs are a little cheaper.

FI set it burn a chip and you can just about forget it. Carb car once you figure out you jetting you might have to make a jet change every once in a while because of the weather but for the strip they work just fine.

Price I think a carb is cheaper.

Carbs are cheaper and (for some) easier to work on, less wiring, less sensors to deal with, less troubleshooting when things go wrong. They're not as efficient though, get worse gas mileage (but depending on how wild the engine is that might not matter really) and get finicky depending on the weather, but honestly my 650 is box stock and i never jet it (mostly because i'm still a bit of a carb rookie). I'm sure it would run stronger with a proper tune (it's also a tad too big) but for what it's worth it's been super hassle free for 3 years.

The beauty of a carb is that for about $50 you can rebuild it and then it's like new again. Also if you take the time to learn to tune it yourself, you'll save a boatload on tuning costs. The best would be to get an air/fuel meter to go by and learn a bit about tuning, then you're pretty self sufficient.

Basically it boils down to this....anything EFI can do, carbs can do IF you're willing to learn to tune it to do so, and they take a bit more user input to keep running the way you expect it to, whereas EFI as mentioned earlier is pretty much a set it and forget. In the end you trade wrenching time on the carb for tuning costs on the EFI, so it's a lot cheaper.

I have a wide band air fuel and it makes any tuning so much easier

Thanks for all your opinions. I do know a little about carbs but was unsure how hard or easy this is going to be to change over. I am hoping to get about 500 H.P.Thanks cms91lx if i have any questions I ask you or post for some help.
