New Carb Time . . . input needed . . .

[D Durden]

Okay, the old 750 double pumper is on its last leg. Is there anything better out there now (under $600 or so)?

I'm running a 409 stroker, solid cam, blah blah blah . . .

Please, no $2,000 setups or "you can do this one for $200 . . . if you have a wrecking yard, 12 friends, 3 garages, some guys from Roush, and 3 weeks . . . ", okay?

I figure I'm going back with a 750 DP, but I thought I'd ask your opinions!

Thanks!

I would say get a carb set up to your specs. I had mine done by Peformance Carb, local to me and have no complaints.

 

[D Durden]

Well, I really don't have any "specs". This isn't an outlandish racing motor that I spend hours on fine tuning, honestly. I drive the sucker to work. It's a pro-built motor with 150k+ on the odometer (getting freshened up this fall).

I guess what I'm asking is "is there a better general carb for my application?"

 

[brianj5600]

There is only a few moving parts. Rebuild it! The only thing that "wears" out are the throttle shafts. Get a book on modifying and building Holley's and get after it. I doubt any off the shelf carb will be perfect. A little reading about circuits and what they do will help a lot with tuning to your motor. A book and parts would be half the price of new a carb.

If it worked well, send it back to Holley for a factory rebuild.

As bad as this sound, I'm a Mechanical Engineer. I work on machines all day long. I bought a Mustang (20 years ago ) to DRIVE. If I wanted to work on her, I'd have bought a chebbie. I hear those guys work on their cars ALL the time.

Right now, I have a guy who wants to buy my used Holley for enough money to make rebuilding it really not worth the effort. I can get a new one for about the same money. Feh, why not?

I understand what you guys are saying about saving money by spending hours to learn to rebuild it, but honestly, I could make more money on my second job to pay for someone else to do the work and still have money left over.

As bad as it sounds, I don't get enjoyment out of working on my horse. I never really have. I'm capable, just not willing.

Why a double pumper if you drive it daily, unless you have no rush hour traffice where you are?

Oops, reread your post. Stroker motor, I think I understand now.

 

[D Durden]

Rush hour? LOL! We have lots of traffic stoppages when the deer start to rut. LOL!

You could send your 750 out to a performance rebuild shop (such as Big's Performance.) They can trick it out, rebuild/recalibrate it, and put it on a Carb Dyno to check the end product.

 

[D Durden]

THAT'S not a bad idea. Who are some of the better performance shops for that?

 

[D Durden]

Anyone had any experience with these carbs:

Stage 5 is $870+ . . .

 

[SoCalCruising]

If you don't want to mess with it: Street Avenger. If want max perf, have your 750DP rebuilt. Ask around and you may find a good carb guy near you. I found a guy who used to own the local carb shop and now works out of shop in his back yard. Just does HiPerf stuff.

Stage 5 is $870+ . . .

and what makes you think you need a stage 5 for a daily driver?

 

[D Durden]

Dats what the people recommend for a stroker motor with heavy mods. She's 500+ hp, solid cam, all that crap. Their lighter duty units are still $670+.

Wonder if they take trade ins or will modify your old carb cheaper?

 

[302 coupe]

I'm sure they will.

 

[D Durden]

Man, when it starts getting into the thousand buck range, it makes me think SERIOUSLY about a 351W Ford FI setup, you know?

 

[302 coupe]

yeah, but luckily you don't need either. But then again, all you want to do is write a check, so its kind of a moot point.
