360 In 72 F250

I have 4 of these trucks. As for your transfer case it is a Dana 24 the np205 wasn,t used from the factory until 74. I have had lots of 360's and a 600cfm carb is more than enough I have replaced all of the 360's with 390's over the last few years and 600cfm is plenty for the 390's to. I have run 750's and the power isn't any better and mileage drops. I personally prefer holleys but you have to know how to tune them I have one Edelbrock and as was mentioned above they are expensive to tune but once I got it tuned it runs good. The Edelbrock I have is part # 1405 which is a manual choke 600cfm and I had to lean it out 4% on my 390 so it should be more than enough for a 360. Three of my 390's are stock long blocks with mild cams stock 4bbl manifolds stock exhaust manifolds and dual exhaust. The fourth 390 I built up a bit it is about 9.5 to 1 compression with a larger cam balanced with a performer rpm intake headers MSD ignition and I still have a 600cfm holley on it.

My opinions/advise are from everyday driving, not the track.
My results on this subject are about driveability not ET's.

You are welcome to your opinion and I mine, unless you are a moderator and I violate some posting rule you have no business telling me to cease offering opinions here or any where else.

Now you are insinuating I'm not telling the truth, don't go there OK.
You go your way and I'll go mine, thank you very much.

Then if your opinion is not back up with facts and hard numbers from testing or wins on the race track , other than your seat of the pants feel. You have no business giving advise to anyone about a subject you know nothing about. Holley disagrees with what you have said and I suppose you are smarter about carbs than they are? I am not I will insinuating anything, I'm flat out saying that you don't know what you are talking about. No street stock 360 will preform better with a 750 than a 600 carb, the cam and cubic inches will not allow it. I won't go my way as long as you seem to want to give bad advise that causes others grief and money. In your lack of knowledge you are probably preceiving the stumble when you punch the throttle, followed by acceleration (slower, takes more time, the wrong way) to be better than a constant acceleration from idle (faster, quicker and the proper way to do it. You probably think a tunnel ram with mechanical secondaries is a great street set up. Parts store guys just love guys like you, "bigger is better" like Tim "The Toolman" Taylor style. Spend lots of money but always a loser because you get the wrong parts.
