Depends on the cars purpose really. My 302 I am building Carb'd. I like it because it makes for one clean engine compartment. Parts are cheaper overall IMO. I like both EFI and carb'd. It's a tough call. I think if I was to do a blower on the motor I would go the EFI route. I think going EFI can allow you to dial the motor better with a blower. Carb'd cars will make more horsepower while EFI cars will make more torque in general.

It really depends on how the motors set up. A carb'd motor usually will flow better because the air basically has a straight shot into the motor where as an EFI motor the air usually has to make its way through the inlet pipes than slammed into the back of the intake than into the motor. EFI intakes have come a long way though. If you take two cars that are identical except one is EFI and one is carb'd and place them in a race it is still tough to call. On a road race track I'd say the EFI car would win because of the extra torque coming out of turns, on the drag strip I'd say the carb'd car. There are many other factors to get into as well.

I know that EFI has a huge driveability advantage due to a way better fuel distribution, quicker cold starts and obviously better gas milege....I can understand that air will pass slower through intake tubes on an EFI equiped engine though....
I could see a slight gain in peak horse power numbers on a carb car, but I think the EFI set up that can control spark and fuel together will always have a broader better horsepower curve....
If you wanna keep it simple and light the carb is the way to go though....

i personaly like the efi. I had both set ups on my 67 an I like the efi. cause you dont really have to mess around with tuning the carb all thew time. so stick with efi if you already have it ![[burnout]](graemlins/burnout.gif)

on an NA motor a c arb will alway make more power
tuning will always be easier on a carb
bur for daily driving u cant beat efi, better gas mileage
if u want max performance then get a carb
but if u want to drive on the street reguarly and want a reliable vehicle, and having the $$$$ to do it, get efi

Yep I totally agree. An EFI car will always win hands down when it comes to driveability, gas milage, and cold start up. These being a major reason as to why you don't see carb's around like they used to be. Anyones who's tried to fire up a dead cold carb motor without a choke knows that you have to properly prime the motor and let it run for a bit for it to really wake back up. I think it really comes down to a personal opinion when deciding. I went this way because I could really care less how much gas the car burns, don't mind the slow cold start ups and just like the reduced costs in parts and the clean engine compartment.

just for general info. when I was street racing as a young punk LOL back in the mid 80's nobody realy feared small block fords. No efi then. Now it is pretty easy to get them into the 12's and faster. I have to say that a properly tuned EFI system would beat a carb setup at the drags. Because we all know that torque and hp win drag races not just hp

EFI can be a pain in the ass though. I have a complete 351efi setup with PMS I may be ditching for a carb soon ![[Frown]](frown.gif)

If you're broke...
If you wanna keep it cheap...
Don't know what you're doing...
or don't wanna mess with EFI...go carb'd.
If you want something reliable..
A daily driver..
Very easy to maintain...
And works really well...go EFI.

How?....
Longer runners make for more torque and shorter makes for more horsepower and obviously the carbed being way shorter it would make for more hp and the efi being way longer would make for more torque. Just tghinking about things logically, don't know if I'm 100% correct

That makes sense...Just remember that "peak" horse power is great, but the higher "average" horse power will always be faster...

actually carbs are reversed
think of a high rpm carb intake, like a tunnel ram, the damn thing is over a foot tall, now that isnt that short of an intake
think of it this way, on a carbed motor, if u put a spacer between the carb and the intake, u get more hp but less low end torque

EFI is standard on some of the fastest and most powerful mustangs to roll out of the dearborn assembly line: The 2003 Cobra and the 2000 SVT Cobra R, in addition, the fact that some some 99-01 Cobras are running in the 11 second zone with an stock little itty bitty 281 cubed motor proves that EFI is superior to carbs. Face the facts, Carburators are dead just like the 60's dinosaurs that could only go quick in a staight line.

hmmmmmmmmmm...... that really doesnt prove that carbs are inferior to EFI but ok. EFI just gives you more tunability than a carb. Thats why for N/A or N20 applications its ok and cheaper to go with a carb, but with boost it is nice to have the tunability of EFI. EFI also has better "street" manners

Been driving my carbed 85 for almost 20 years and have never had cold starting or drivability problems. The only thing that sucks is... Carb + smog equipment = PITA ... If you're going naturally aspirated and you don't need smog equipment, carbs are easier, faster and cheaper than EFI. If you think there is any possiblitiy of adding forced induction in the future, EFI is the way to go no question. But, don't buy into all that poor drivability crap regarding carbs. I'll idle all day with any EFI Mustang out there, even with my F303 cam. Fuel mileage? Ok, EFI has that over me

An open carb spacer adds more plenum volume that kind of acts like a reserve when the engine needs more fuel at air at high RPMs. Which, of course, results in increased hp.
A 4 hole carb spacer would be like adding longer runners and resulting in more torque and less high rpm horsepower.
