Carb Question

[njdevil2]

Here's a Question:
I have a 360 Stock heads (1.88/1.60)Performer intake port matched to the heads, "medium"cam, 9:1 comp, stk bottom end, hi-press oil pump, 2.8k stall 727 man/auto B&M shifted, 8.25 with
2.94's (sure grip 3.55's coming..) It ran 13.6 in my Demon
The question: I ran a 600 Edelbrock (it's toast), I wanted a thermoquad. My (VERY) reputable rebuilder recommended a (GASP) Quadrajet!!. I wanted a t-quad because it would react better with demands made by the engine, I just felt better about using a t-quad. I figure more that 750 cfm is too much but the t-quad would work well with this engine(it had one before...)
Well, what does everyone think? Thermoquad, Q-jet, Edelbrock or a Holley? I could use a little information on this...
Thanks

holley 700 doublepumper carb. for your combo, it would work great.
i'm a big fan of holley carbs.

[rumblefish360]

Use the 800 cfm T-Q if thats your flavor. (I like'em)
The Rochester is more likely to hand out poor mileage. (Thats the complaint I hear most often)
Skip the Edel. junk. I never have good luck with Edel. carbs. OE Carters are good by me. Even the new ones, I have good luck with. An AVS is a good weapon of choice. The choke hook up on intakes without the well can pose a problem for those not inventive. (Drill the carb out for an electric choke or use a cable for a manual choke operation.)
Carter rated there small carbs @ 630 cfm as per Carter tech line.
A little grinding on the boosters can net a few more cfm. Be careful. There NOT sold seperatly. Only on new carbs.
Holley are very nice. A little hard on keeping tune sometimes for some. Not my fav. carb. But they do/can make a car scream.

Thats how I see it in the order I wrote it in and how I would choose or use a carb.

[ehostler]

Definately go with the TQ.

[MoparMarcIdaho]

T quad probably better milage but I just have to thing a good ol AVS would be snappier.And no plastic float bowls to warp and crack either.

[DEMON SIZZLER]

I would also say use a T.Q. but not just at random. Find a 1972-1974 850 cfm 6000 series T.Q. This is because your engine is not a smoger engine and the mods you have done. 1975-up carbs are smoger engine calibrated and would perform poorly on your engine without mods to disable the smoger lean circuits. All 1974-1976 360 hp engines used the 850 cfm T.Q. so the 850 will be right for you.

Look for #'s 6090, 6166, 6453, 6322, 6324, 6518, 6545, 6615, (9014, 9015, 9024 9036, are the acception #'s). These will all tune on your 360 and will perform in both mileage and hp, DAVID.

I'd go with a thermoquad. They were stock on the 360 and they are 800 cfm. You can get one from Advance auto for about $189.00 with life time warranty or get one from www.thermoquads.com .

[jerry crawford]

Im an Edelbrock guy. I have had a few and love the ease of tuning and the reliablility. The electric choke works perfect too. I have a 383 in a 69 Charger. I found a dual quad for it and will run two Edelbrock 600's with progressive linkage. If I had your engine and setup I would run a 600 Electric choke without emissons. Too big will hurt you more than too small. I think 600 is more than enough. You have to remember that Edelbrock is VERY closely based on the original Carter design. It works. And no power vavles to blow.

[ehostler]

Maybe you didn't read the original post. His EB is no good (not unusual).

[njdevil2]

I have the opportunity to go back to the Edelbrock, I was satisfied with the performance, I just felt the TQ was better for
street/strip use. Why would this guy suggest a QuadraJet?
I thought that was strange.....

[aspen 360 4bbl]

TQ's are getting kinda scarces, but there are some poeple out there who can help www.thremo quad.com. he's a guru ......with parts too boot..

Because, he must be a chevy guy and those junkers are a dime a dozen. YOu can get them all over my town all day long for 20 to $40 bucks. The TQ is much more throttle responsive than any Edle,quadrajunk, or holley. It responds very quickly for lots of low end tq and then it flows plenty at higher rpms since it maxes out at 800 cfm. Besides, you can get them all day long with a warranty from Advance auto or from demon sizzler at www.thermoquads.com . And one other thing, they are much easier to adjust and set up than a quadrajunk or edel. Plus your local NAPA has all the parts you'll ever need, like rebuild kits and brass floats and such.

T.Q. or 650 Holley

[rumblefish360]

njdevil2;

Get with DEMON SIZZLER.

[njdevil2]

rumble,
yeah, I'm definitly thinking of calling him(d/s r u listening?).
I have to out of town tomorrow, and the only reason I was going with the "local" rebuilder is the cost. I have some cores and he'll do it for $100 plus 3 cores & year warrenty. I'm kinda bucks down, but if I can swing it, I'll call demon. He has a great web site & a lotta info.

[rumblefish360]

Am I listening or Demon Sizzler. (LOL)
Save your pennys. Demon Sizzler is VERY good and can tune it for you at his shop for your car very well.

[njdevil2]

Ok y'all, I called Demon Sizzler today, and I'm savin' my scheckles to get me a TQ.
He's a great guy, talked to me about the car, so come Monday I'm sendin' it out. I'll let you know how it turns out.
Thanks everybody for your help

Rich

[njdevil2]

A quick update:
I ran the car on 1/8th mile with a marine Holley(don't ask...)
ran 10.00's @ 71.9. 2.92 rear gear, tall rear tires 'an all that.
Demon Sizzler's got my TQ and I'll replace the Holley with the TQ and see what gains I get with no other mods. OBVISOUSLY I'll do more, just want to see what happens with the carb thing.

[dwc43]

Nice run, got what you got in it.
