what is a 5.8 HO??
I was calling around the other day for rebuild shops and they quote me 2 prices.
I have a 1982 Ford Bronco - full size. It had a 5.0 in it but we put a 5.8 from a 1983 van a few years back. so anyway.
what is the difference between a 351W (5.8) and a 351W HO (high output) ???

so is there any reason I cant put a 4 barrel on a NON HO engine? Just because it came with a 2 barrel carb - does not mean I want to run a 2 barrel carb.
I am looking at putting a Holley Truck Avenger 670 CFM.
My buddy has provided me with a Holley center hung 750 and says it will run just as good as the truck avenger if not better on the hills and such when wheeling... But I want the truck to run like if just left the factory. She had very little trouble with stalling and such when we got the rig. But I messed up and dropped in a 351W that was not in as good of shape as i was thinking it was and have never got it to perform as well as I promised her.
So a new rebuilt is in her future. I am just trying to find out what carb to run to give her the most bang for her buck. and We have talked about going EFI - but that is not in the cards.
A buddy said I should skip the RV cam for the engine and just keep it all stock so if she ever does go EFI someday - I wont have to worry about the computer coughing at the cam.
Thoughts and ideas????

Most bang for the buck is buying a Holley 500 cfm 2 bbl and bolting it onto the stock 2 bbl intake. 4bbl performance in a 2 bbl package. And that's with a new carb, even more bang by buying a second hand 500 , kitting it if needed and then bolting it on.

i wouldnt run a holley on a 4wd at least not the older models. they flood easily when bouncing around and blow power valves left and right. most need modifying to perform well in a 4wd application. i hear the truck avenger though is a good carb and doesnt have these issues.

As far as putting a Holley 500 2 barrel on a wheeling rig - no chance of making that kind of mistake again. Like Kemicalburns said - they are not great off road carbs. she is currently running a holley 2300 carb and has been for about 2 years now. it was completely rebuilt and ran purfect when I put it on her rig. but now she has very limited hill capability. Of course we might be pushing the limits of angles even for a truck avenger carb. But it has got to perform better with a new rebuilt engine and a well working fuel system.
I have heard and read good things about the Truck avenger carb and that is one of the reasons I am asking questions about using it for my application. Yes the truck is a daily driver BUT she does like to go off road and she ain't no pansy - she plays pretty hard and has a truck that shows all the signs of being a true off road rig.

The holley truck avenger is not that good and like all holleys needs to be messed with all the time and every time the seasons change. I got rid of mine and bought the new Edelbrock off road thunder and have not touched it since. It was cheaper and definitly handles hills and everything for that matter noticeably better. I would not go with a 750 that is way to big. try a 600 or 650 at max if your going with either off road carb.

It's more likely the rest of the engine is out of tune, or you're running crappy fuel with no filter. If you have to keep fiddling with a Holley, that's just a sign that you don't understand them to begin with.
