360 carb recommendation

I've seen a lot of guys on here that are doing a 318 to 360 upgrade and I'm wondering what carb CFM is recommended for my 360 build.  My intent is a mildly potent 360 that runs on pump gas, a good street/strip machine.  I've noticed several 360 builds using 650, 750 and TQ's.  My plan is an RPM AirGap intake with stock heads for now, a respectable cam, and headers.  

What would be a good size carb to handle this and maybe some future performance upgrades as time goes by?  

Just wondering if 600 CFM is not enough...but 750 is overkill?  

I've been looking at Edelbrock Performer or Thunder series.  I'm also wondering if anyone has had experience/luck with Edelbrock's re-conditioned carbs?

Don't waist your time with the eddy or thunder series carbs. For a totally stock 360 the thermoquad is a good pick. For a warmed over 360 the Holley HP 750 DP is the ultimate carb. When I say warmed over I am talking 450+ hp.
Good Luck.

             What do you mean? WHy?
      I thought they were great street carbs?
   After my first 4 deployments I had a 360 built for me (on the 5th excursion)
       with a 800 cfm 'eddy' carb and around 450 hp- no problems

THERMOQUAD. Just make sure it's a 1974 or earlier.

Why? cause they are 40 yr. old technology. The thermoquad was ahead of its time when it was released and in my opinion should have been kept around and not the AVS carbs which are known for not running well in the heat.
The Holley HP with its latest technology upgrades will slam dunk the AVS carbs all day on a 450 HP 360.

My understanding is that the Thermoquad is only compatible with certain intakes.  I had always planned on an RPM Airgap but I don't think the two will work.  What intake is recommended for a TQ?  

Eventually I would like to run a TQ.  I acquired an old Thermoquad last year but I'm not sure of the quality and application.  It has the numbers 6-2146 which from what I can tell may have been from a mid 1970's truck.  Any idea if this is or can become a good 360 performance carb?

I have a Eddy Performer intake on my core 360 that I thought I would run with for now so I was looking for a less expensive temporary solution...just not sure which CFM would be the best fit.

Your cheapest solution to running the theroquad carb would be to find a 74 up 4 barrel manifold for your 360. Usually can find these on e-bay.
Good Luck Cool

Thermoquad, that was the same question I asked. I did a warm over on a 318 and I put one on. I am impressed with the throttle response. It should yield me plenty of power and good gas mileage. I must admit I was apprehensive about dealing with one, they can be complicated. But on the other hand they are also very easy to rebuild. Mine has the larger primary and secondary bores which I believe would be considered an 850cfm on a 318 and it runs awesome.  If your looking for budget it's the way to go.
