On the dyno, measured airflow on my test mule was less than 600 cfm with any carburetor I tested on it. Test carburetors ranged from the 625 up to a Holley HP950 that utilizes a venturi size similar to a 750. I'll see if I can find the cfm comparison sheet or print out a new one. Too big of a carburetor reduces the signal due to lack of vacuum at wide open throttle. Keith www.dunnuckracing.com

Quote: we have the street demon and the quickfuel mentioned above. what are some other good carbs in the pricerange between 650 and 750 cfm? I prefer vacuum secondaries I misunderstood what you meant by "we have a street demon". And are you now rethinking your position on the secondary actuation? Master, again and still

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.

Keith Normally I'd agree with the statement but I keep circling back to my Duster- Stock bore 5.9, Enginequest heads with 1.88 intakes, Edelbrock RPM intake and a Compcams roller and exhaust manifolds. The engine is mild enough I have power brakes and a stock converter but would draw a vacuum at WOT after a second or two. Classic indicator of being under carb'd. Replaced with a 750, problem gone. I say problem because it was popping the overdrive back on, I have a vacuum switch for OD override. I guess the question would be the definition of mild build. If it is a stockish build then for sure lean towards the 625, anything more and I'd say the 750. "I think its got a hemi"

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. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

More info as we might be able to help you fix what's going on with it. I ain't a CFM problem (625/5.9) tho you have a pretty healthy build it should not be bogging live every 24 hour block of time like it's your last day on earth

I'd be more than happy to let anyone drive the car if they are in SE CT and they can see for themselves how the car runs and throttle response. "I think its got a hemi"

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,.....

Charger_440 OP super stock C Joined: Jan 2003 Posts: 715 Tulsa, Oklahoma	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?

If it is advertised as a Ford carb, then that linkage if for a Ford. Seldom do the carbs come with a "MoPar " linkage set up. If I got this right ... The OE iron intakes use Carter's. Any Edelbrock will bolt on because of the dual bolt holes on each corner of the carb mounting pads. If the Holley does not have this, then it will not bolt on a OE intake. Save certain car/model/engine packages that came with a Holley from the factory. On your OE small block intake, you can readily bolt on any Edelbrock. Look carefully through the Edelbrock catolog.

He told me to bring it by and he would get them to re-rebuild it and ensure that it's right this time. Last edited by charger_440; 03/14/14 05:03 PM.

We have used this shop before, never had this issue in the past HTH can you have a dirty "rebuilt" engine. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

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.
