i am glad this was posted!!! on my 79 f100 302 i am having carb issues as well, my choke wont set and it is just a piece, however i dont think it is the original carb for it since the fuel filter is different( had to get on for a 400), so i have been comparing carbs and been looking heavily at the 600cfm edelbrock with performer intake from summit for 450. being on a budget, thats probally the way ill go do to the fact that its cheaper, however, about the installation that someone mentioned, has me worried about the edelbrock. i just need it for a daily driver and maybe the occasional tow vehicle. i think i will start looking at the holley more closely. Thank everyone.

PS welcome to FTE from one FNG to another. lol

 

there should be no issue, mine was easy as pie, i can't see issues with the install, its pretty simple stuff and these trucks are cave man simple compared to the bothersome computer stuff we are forced to buy from auto makers, all i know is be sides some slight aerodynamics which is so slight, our trucks when maintained and given proper tune ups can give modern trucks a good run for there money on fuel economy and i know there's hybrids and the famous shut pistons off to run on 4! but that's still not a huge leap in gas mileage!

 

go with the re manufactured edelbrock 600 cfm performer carb with electric choke for 249.99 and edelbrock rebuilds them and you can find them from a good speed shop or right from edelbrock, and i got my edelbrock performer intake for 169.99 so it works out to about 450 plus tax, and this was up here in Canada where prices can be really expensive if you don't watch your back, edelbrock is the best in my eyes, and i would not want to try the rest, my dads 84 5.0 mustang had a holley and he swears to stay away from that evil woman! and i have seen the trouble first hand of it leaving you stranded! and it not idleing right or out of tune which made it run like a turd, and the motor was fine and has been rebuilt, that was a reason he switched to a 94 5.0 and got away from carbs, i showed him the edelbrock carbs and he says there the best he has seen, now that i said lets get one for my truck, i have seen the worst in carbs (holley) and the best in carbs (edelbrock) and a fast fact weber is the same carb as edelbrock, mine says weber right on the side, and webers where some of the best carbs in history and famous in the 60s mustangs and Shelby's and rods!

 

Kirk, and all others on this thread,

Kirk was right. I must have used too many thumbs in my "rule of thumb".

2 barell CFM DIVIDED by 1.4 = 4 barell CFM
Or, another way
4 barell CFM TIMES .707 = 2 barell CFM

Sorry for posting bad information and I apologize to all for any confusion.

This could cause a battle you'll never win between holley and edelbrock. I've had both, but think this is just another preference.

 

ya but the edelbrock never leaks fuel!, its gasket is above the fuel level! that is a plus on a lot of levels, i hate to see a leaky carb! spilling precious gasoline all over the engine, that is a fire hazard! plus i no one can even mention one thing better about the holley over the edelbrock carb, all i know is that holley carbs are a real pain in the rear end when it comes to fine tuning the carb, my best advice, "if its holley throw it away if its edlebrock bolt in on! lol i know its personal choice, but i just love my edelbrock carb! and it matches my edelbrock performer intake so well!

 

I hate to be the naysayer, but if you have a motor with over 130K on it, you might be wasting your money trying to wake it up. Yeah, you might get more zip out of it, but you might wear it out faster playing with your new zip.

 

I am new to this forum, but not to fords so i would like to offer my two cents. if your truck is a daily driver then the holley will work fine. everyone of them that i have ever had didnt do so well if they sat for awhile. i switched all my fords over to edelbrock because of it. it was a PITA to take one of the toys out and only make it to the end of the street cause the carb was leaking. havent had that issue with the edelbrocks. again, just my two cents..

 

Yea, i've even seen it at cars shows (cars that don't get run that much) The cars that have a hard time starting have a H_____ carb. I'm gonna run an Eddy on my 1978 400 F250 Crewcab.

 

I've had Holleys leak, but usually tightening a few screws made the leak go away. If that didn't fix it, $5 worth of gaskets fixed it right up. I have noticed that the higher mileage units have tendancy to not hold a tune to save its life. I had a couple I had to tinker with at least once a week to keep the idle mixture set correctly.

The Edelbrock carbs look nice, but I have had mixed luck with them as well. Tuning always seems to be an issue with these things, I always get flat spots, and am too lazy to do anything about it except learn to live with it.

 

I have never had a problem with a holley carb. Learn how to tune it. An Edelbrock out of the box is not tuned correctly for your vehicle, maybe it fired right up, but it still needs to be adjusted for optimal performance. I bet 90% of carb probs is because of not knowing how to tune it correctly.

Remember, you can tune a Holley, but you can't tuna fish.

Boy, Rockstone, some people really know how to stir up a hornet's nest!
But, after swatting away the hornets, I agree completely with you and UTfball68.
People have preferences... That is what makes the world go round. Regardless of which carb one chooses, there is a certain amount of maintenance required. Period. The required maintenance is different between the carbs, but still required.
I prefer a Holley over the Carter AFB/Edelbrock because, in my opnion, the Holley fits a Ford better and makes for a cleaner installation. I have installed both types and work on both. Again, my preference is a Holley.
With that being said, they are both good carbs. Both have been around, in one form or another for over 50 years. Most, if not all, major manufactures have used both carb types, on all types of engines.

Listen to all the pros and cons. Do as much, or as little, research as you want. Then make up your own mind. As long as you get the proper size carb for your rig, there is not a wrong choice, Edelbrock or Holley, Holley or Edelbrock

Thank you!

 

I am looking into a holley 750 to put on my edelbrock performer 390 intake. Does it bolt right on or do I need some sort of adapter?
