holley rebuild

When i bought my camaro 2 yrs ago it had a holley 4160(1850) on it. It is the cheap rebuilt one and i added a electronic choke. I always had problems with the carb and then the motor died one day due to lack of oil pressure. I tore apart the carb and just recently..."bolted" it back together had tight. Rather than buying a new carb for my new motor, do you guys think that if I rebuilt the carb it would work alright. This is my first experience with holleys and i wasnt impressed. I know they are good carbs but could something be wrong with it besides gaskets or powervalve or jets. Should i give this rebuild a go or not?

Personally I'd trash it, but I've always hated carbs without center hung floats. What kind of new motor are you going to put in? Get a carb for it.

but isnt there a float bowl type conversion kit that basically turns it into a DP with vacumm secondaries.

what kind of carb would you guys recommend for a mild 355 with a 2500 stall converter, th350, and 3.42 gearing..keep in mind...cheap is good for a high school student. I do not want to spend 500 on a carb


also those road demon jrs. are about the equivalent of what i already have...the 4160 series correct?

Just get the Holley rebuilt properly by a shop that knows their business. It should work fine once dialed in.

Edelbrock Performer carbs are about the cheapest if you want a new carb.

Do you have a square bore or a spread bore intake manifold? If the latter, you could get a QJet and forget about those other fussy carbs that don't give decent mileage.

The cheapest thing to do would be for you to rebuild the carb you already have. 600 CFM will feed a 355 up to 5800 RPMs - and that's assuming 100% volumetric efficiency, which is rarely achieved.

You didn't define what you want to maximize with the car. That's important. If you want best 1/4 mile performance, that's a different answer than what will give best gas mileage; and if money spent needs to be minimized, that's still a different answer.

Pretty simple. Have a can of real carb cleaner to dip & soak the parts in after disassembly, compressed air to blow out passages after the soaking, and follow the directions in the kit.

Those are just about the easiest carbs to rebuild on the planet.
I've done holley 4160s, quads, and edelbrock (carter), and the holleys are the easiest. The only problem is to get them in tune. That is a b!tch.

Buy a good book or two on Holley's, HP series are good, then learn to do it yourself. One piece of advice...always buy genuine Holley rebuild kits, particulary Holley Needles and Seats. #1 parts problem with Holley's is cr*ppy third party Needle and Seats.
