I recently bought a 85 W150. 360 - 727 - 9 1/4 rear... yada yada yada
Anyway my problem is it's running too rich. I never had a vehicle with a carburetor so I know nothing about them. A friend of mine has a few 70s big block Camaro's and he said that my carb is too big for my stock engine. His advice was to get a Holly and tune it mean, or get a stock 4 barrel.
Anyone have any advice as to what I should do here? I'm looking for different opinions and advice before I make a final decision.
I really didn't want to make a new post, but after searching I really didn't find much. So basically what is the best carb for a stock 360?

Depending on the size?What model?
But you can still tune it within reason.
Adjust your mixture screws,change rod/needle,jet size,change springs.
Getting a holley,with run fat to start will require similar tuning anyway.

I am running a stock 360 in my 72 power wagon and have a 650 edelbrock on it. Runs very well although i have had a few problems with tuning it properly at times. i have found the best way to start out on a carb is turn the adjustment screws in all the way then back both out approximately 3-4 turns fire up the motor and go from there. Hope this helps.

Ok so my Edelbrock is a 1406...
How do I know what size jets to buy for my engine?
What I really want to do is tune this truck to the best it can be. Is that possible with an Edelbrock or should I get a Holly (the only reason I'm saying Holly is because I heard that there are many more jet sizes for a Holly)?

That is a good carb for you,I think it is better than a holley and easier to work on.
You can get a calibration kit(part# edl-1487,$38.00 at summit),gives you a variety of jets,rods,springs and some tips to help tune it.
Which jet is trial and error,but it is not hard to switch them.
You are about 2 hours away from me(just north of Pittsburgh),if you want,you can get the kit and come by and we will get you set up.

Thanks for the part number!
My truck has absolutely no power, but guzzles fuel like powerhouse!

Get a few books on carburetor theory. Read, and re-read them. You can't tune anything until you understand how it works.
If you just throw jets and rods, etc., at it, you'll get nowhere fast.

You might have a timing issue along with the carb adjustment.The a/f screws on an eddy carb are for idle quality only.Try turning them in gently all the way and back them out 2 full turns.Also make sure the choke flap is all the way open or it will run like ass.I suspect the timing might be retarded to like maybe 6 degrees btc which on my truck was a nightmare!!

Do NOT waste the money on a Holley; you "think" its thirsty NOW? Put the Holley on it; you'll see what thirsty is; that 1406 is about perfect for the 360 size wise. Remember; ratings are nice for bragging rights but an engine will only suck as much air thru it as it can handle; it wont gulp any more air out of a 750 just because the carb's bigger!
and being a mid 80s 360 if its as stock, they had the most woeful compression ratios since I think the original flathead Jeeps! meaning thirsty and not as much power as one would think that such an engine would produce! WHy Mopar put dished pistons in the 360's, I do not know. But in so doing they castrated that engine--big time. I remember thru the 80s some of the 360s (the "heavy duty" ones in 1 tons especially) were only advertised as having 7.5:1 compression! A stock 2 bbl Holley from earlier 360s (70's era) was about 350 CFM; if its stock, another great choice would be a stock type Carter TQ; IF they are set up right.
Has someone messed with the stock out of the box jetting of that Edelbrock already? Hows the float level? Is the choke set too rich? Timing chain sloppy? Advance working in the distributor? Exhaust clogged? Heat riser sticking? Heat passage in the intake plugged up? Theres alot of other factors here than the carb that need considering; but that said, there's alot of people out there, that have NO IDEA how to correctly set up a carb. I'm "decent" but don't consider myself an expert; the ones that do, can be some of the worst choices to touch your carb. Tell your buddy to go chase his tail on his Chevys some more.
