i have a 360 with stock bottom end, 596 heads and Weind stealth intake.. gonna run eddy 750 and not sure on distributor yet cause i haven't found one... it will have long tubes and be in a 3600 lb car with reverse manual transmission with 2500 stall and 3.55 gears.. looking for suggestions for a decent street cam with a nice thumpy choppy idle, still has enough vacuum for brakes but has some decent power. Engine is my profile photo

You may consider something like this.
I have the Lunati 10200701 in my 318, and wouldn't use it again.
There are a few here withe 703. @72bluNblu is running the 10200704.
If I go with a hydraulic flat tappet, I'd go with the 703 listed below.
Voodoo Hydraulic Flat Tappet Cam - Chrysler 273-360 268/276
I am more likely to go with the solid, linked below. I've got 4.10 gears, 2400 stall (I know the TC doesn't match real well, being 100 less than the cam manufacturer recommends but I did talk with them and they said it'd work ok. I want better than ok but it's what I have right now). 308 heads and an RPM Airgap, I'd like to run a 750 AVS2 on this motor, but I have a 650 Holley sitting around, so I may just cheap out and use that instead. Doug's D453 headers. I'll probably just slap in the Unilite dizzy I have sitting on a shelf. I doubt I'll be using the stock bottom end, but I'll stick with the 3.58 stroke. In the next couple of months, the block is going in to the machine shop.

Start with a better converter. What you want is a combo killer. It's not 1979 any more. A 3500 converter would do you wonders.

With an 11” converter- the smallest of the Howard’s Rattler or Comp Thumper.
With a 10” converter, you might step up to the middle one.
The middle version of either might make the Ede carb a little unhappy down low and at around idle.
For something with a bit milder nature at idle, something like an Isky 270 Mega cam or a Comp XE274.
I’m sure there will be many more suggestions.

Isn't 3500 a bit much for a street cruiser?

what ottmunder said
the Lunati 701 is way too small for his converter and gears
but if you have stock converter and mid range gears and stock compression it might be the best cam for you- or the next size bigger depending on how you want to drive it- what power band
imho choppy idle and power curve does not compute with a low compression motor
256 Howard would work the one with 15 in the notes column
I've sold lots of MegaCAms and was a WD- you would give up torque in your build, but it revvvs well if you are going to buzz it up but not with your gears
do a search for AJforms and read some of his posts on dynamic compression and match up with your build
at least you do not have a 2.74 rear end and stock converter which does give you some leeway

Ottmundr’s first Lunati Hyd. cam and PRH’s Comp cam are very close to each other. Ether are an excellent choice that will work with your current converter.
I’d run ether one of those right quick!
I run the Hyd. roller version of the Comp cam in a 360 w/a 2500 stall and 3.55’s on 26 inch tires. 1.6 rockers get the valve up into the ported heads better flowing area. It is a really good street cam that cam make some decent power if the rest of the system is up to it.

I am running a 703, its ok really nothing bad to say about it.
It idles with decent vacuum 15 inhg, pulls right from idle, and revs good.
Engine is a 340, but choked off with exhaust manifolds.
4-speed 3.23 its a nice cruiser.
No super tire burner with 28" tires.

i'm gonna get the wrath of the quarter milers but a stock 8.1 or so comp 360 will want a short duration cam for street duty.Keep your tires around 26 inches and a comp 256 or similar cam will blow the tires out easily and be a menace street light to well past highway speeds.

Nope. Call PTC or someone and see what they say. It's most likely I'm wrong.
But a 2500 converter is virtually worthless IMO for anything but a dead stocker.
And when you handicap your combo with a converter that is too tight, it changes everything you do.
You can run more cam than you think if you don't cripple yourself with that converter.

Only if you think a 2500 converter is a good thing.
Otherwise, the OP is just wasting power and it has nothing to do with a quarter mile.

well...i do and my current ride uses just such a converter.With the small cam the 340 it pulls hard on the street, gets good mileage and i love it.It would not be best for the quarter mile though. But yes my last build had a 9 1/2 dynamic with a much higher stall and it certainly improved the bottom end. I just did not like driving through it repeatedly when pushing it during regular driving.

Who said ANYTHING about a 9.5 inch converter? I'm pretty sure an 11 inch converter can get to 3500 and I'd bet all I have you couldn't tell it was a 3500 with a gun to your head.
Converters have improved like most everything else. The days of a 2500 converter in anything but a dead stock combo should be long gone.
If the OP wants a 2500 converter than that's ok. But when I see what he's doing that pops up as a big red flag. The car is heavy, has a fairly tall gear and isn't making a bunch of torque. So handicap it with no converter and then buy a cam to try and cover that up. Then it will be a ***** to get the tune up correct so it doesn't rattle its brains out trying to get it to move, and every time you get to tip in it does the same.
So you retard the timing (power loss) and then to get the rattle out at tip in you end up unplugging the vacuum advance (another power loss and the fuel mileage goes straight in the crapper) and where did the OP end up? With a confused, hard to tune, no fun to drive fuel gulping pig.
I'd at least call someone and see if I'm nuts. I could be dead wrong. But I doubt it.
Nothing like a pro. There are a few places to call for this.
Dynamic, Ultimate, PTC, etc.....

i guess i need to find some phone numbers to these places and make some calls

I like the Comp XE268 for your combo.
Has mild manners when cruising, but will hit hard when you stomp on it. Also has a nice chop to it.
All in all, a very good cam for a mild 360.
Also, not a fan of the Ede 750. Had a hard time getting it to run well.
I like the Ede Thunder Series 650. Perfectly matched for a mild 360.

is there a summit brand equivalent to the comp XE268?
Eddy 750 and Eddy 600 thats been modified is only carbs i got to work with
No.
Try the 750. If you can get it to run well with it, great. The smaller unit only gives up a little power up top but adds a nice throttle response.
If you find that you can not richen up the secondary side enough, give me a PM.
For what you have and intentions save your time calling high end boutique converter companies expecting a “just for your setup” custom converter. Waaaay overkill. You have what looks to be a common everymans mild setup of which there are plenty of in stock dime a dozen converters that will do the job. Just call a well known company such as Turbo Action and get a 17805ST if it’s a 727, or 19802ST if a 904. Same converters brazed and welded up, cranked out for years. You call some of those others you will get the same converter they crank out for most everyone else, just be paying more that’s all. They won’t be brazing fins at angles specially for you, trust me. It’ll be pulled off the shelf, off the stack or welded up for the umpteenth time just like the ones before....exactly the same. Spend your money wisely

i currently run a cheetah reverse manual valve body in my built 904 transmission along with cheetah sts shifter, so Turbo Action might be a good place to start.

no 268 anything no 270
his build and what he wants
why keep suggesting big cams
let's see the compression but we know what it's going to be
no matter what converter he needs big fat torque curve
he can afford to give up no grunt on the lower end with those gears and tires
you note the 250 lunati has about the same lift as the 268 or 270 comp but closing the intake 10 degrees earlier makes a lot of difference
the 256 howards closes the intake within degree of the lunati as it is on a narrower LCA
256 comp is a girlie cam
the lunati and especially the Howrds require careful attention to detail- but then they all do

I have tried the Ede 600, 650, 750 on my 360.
The 650 is my favorite of the three, followed by the 600, then the 750. If the 750 isn't working for you, don't be afraid to use the 600. It is a great running carb.

IIRC Edelbrock changed the Venturi or something (maybe the booster...I didn't pay a whole lot of attention when it was being discussed) on the 750 and it makes getting the fuel curve in shape a bit of a buggar.
Now that I typed that, I *THINK* they changed the booster.
Either way, it can be more difficult to tune.
