The 625 version is enough carburetor for a mild 360 unless you plan on some major upgrades. Keith
Bingo and bingo again!
I had a 79- 360 that I used a Fed-Mougal made Carter 625 AFB on top of a iron TQ intake. Factory exhaut manifolds into a dual exhaust. It was a nice upgrade. While not a big fan of an AFB, it did scoot along real well.

Let me see if I can help. I have 5.9 Magnum, KB .04 over pistons. Air gap intake, Hughes roller cam, Indy x heads. Headers, MSD ignition. I am currently running a 625 Carter that works pretty good but bogs. Tried an Eddy 750 and it killed the engine. I think the 625 Street demon sounds good for my set up and the ops. I think I'd like a 670 Street Avenger. Had a 770 on a 383 that worked perfectly.

I was down at the Indy Cylinder Head trade show and swap meet today where I ran into Randy Bolig. He told me the article I wrote for him (Mopar Muscle) where I tested several carburetors on a mild 360 will be in print in the next couple of months. If you can wait that long please do yourself a favor and read it before you make a decision. Some people's old favorite type carburetors dont hold up so well. And no matter how the secondary side is adjusted doesn't matter when the metering is all wrong for today's fuels,..... Keith
Yes I am very interested in reading the article.

ok, so, silly question, but, hey, this is how we learn... if i see a carb advertised as a "chevy carb" or "ford carb" is this just a difference in linkages? or is it also a difference in the mounting pad bolt spacing?
i.e. (and i am not looking at used carbs) a lot of what you see listed on craigslist is used stuff, you see, for example, holley 4 barrel small block chevy, or quadrajet replacement
how do i know what would bolt onto that OEM 360 cast manifold?

Thanks for the reply Rob. I've got an Eddy 650 on my 71 javelin, and i dont know if I'd want another. It seems a little finicky.

Thank you again guys for all of the info and opinions. I did end up going with the street demon 625. i figure since i want to go fuel injected in teh next couple of years, at leat i can use this carb on one of my other cars. None of the others have enough motor to use a 750 at all. lol.
thanks again everyone!! Much Appreciated.

I got it at gran prix speed shop in tulsa. Itll be a week or two before I can assemble the engine. Unwrapped the rebuilt engine to find it dirty and all internals still rusty. Had been wire brushed not hot tanked, grit in the assembly lube and all in the bottom end.....its going bk to the shop on saturday. We have used this shop before, never had this issue in the past

the guy i talked to was very surprised to heaar this, and glad to make it right. He was glad that I caught it as well. He told me to bring it by and he would get them to re-rebuild it and ensure that it's right this time.

well......that's the longest week or two I've ever experienced. Today, they FINALLY got the engine finished up and it's being delivered by the shop this evening. It has been one complete fiasco after another. Lies, excuses, delays, etc. but in the end, it's finally done, and finally correct. They not only did the warranty work to rebuild it right, but, in order to make this all right by me; they also did, for free, bronze guides, hardened seats, 3 angle valve job, and internal balancing. The engine, this time, actually looks like a rebuilt engine should. It's clean, well lubed, everything is right1 I am a happy camper!
Does anyone know what the typical toleranaces are for internal balancing? Their performance guy wasnt there when I was, but the manager kept commenting on how well it balanaced out and how smooth it should be. He said it balanced to within either 5 thousandths or 5 hundred thousandths. He couldnt remember which.
Come to find out, today, at this ENGINE REBUILD SHOP their only engine builder is only there 5 hours a day and their performance guy is only there 3 hours a day. The manager actually said "The other guys might do some mechanic work back there, but after 2PM, basically all we do is answer the phone."
All I could do was shake my head. I'm just glad to have it finished and be done with them. Now, i just hope that it's all as right when ig et it on the engine stand as it appearded to be in the shop.
