Just got my 81 Malibu wagon up and running, but I need to get a different carb. Here's what I got.

81 wagon, 383 with Vortec heads, 9.5:1 compression, 234/244 .487/.508 hydraulic cam, th350 with 3000 stall, and 3.73 gears. Has a pro products "crosswind" or what ever the RPM Airgap ripoff intake is. Converter is on the tight side.

Car will be a street car, may see the track once or twice a year at most.

Currently I am running my old 600 Edelbrock, but I know it's too small. I've had more hands on experience with Edelbrocks, so thinking about a 750. But I've been told I should try a 750 Holley double pumper. I'm willing to tune on whatever I need to, but I really don't want to spend all summer trying to get this to run right.

Thanks!

I guess depends on how you plan to use the car... I had a setup similar to yours in my last 68 and I used a 750 vac sec carb. I loved it.. on the street and strip. I'd prob go that route unless you take it to the track a lot.. then maybe dbl pumper.

Street time, driving to work 1 or 2 days a week. And cruising on Saturday nights. Ovbiously not concerned about fuel economy. Just want it set up to run as well as it can.

just search craigslist, you can find 650dp or 750dp or around 100, another good one is the 750 vac secondaries. Those are among dime a dozen. If the price is right get one.

I like the Holley 770 Street Avenger. If you had a looser converter I would go Holley 750 HP.

I'd say go either Edelbrock or Holley Vaccum Secondary version... No reason to go Double Pumper... If you can stall the car to 3000 and leave the line without spinning thwe tires much, then that DP might be a little better, but no reason for the secondaries to come in before the car can handle it...

I have swapped several street/strip cars from DP to VS Holleys, and always worked better. Not as impressive, but better functioning and alot better mileage/driveability...


If you are comfortable with the Edelbrocks, I'd go that way. I have helped buddys swap from Holleys to Edelbrocks, and never any significant difference at the track... In fact, most ran better times with the Edelbrock, along with better mileage, etc... These were all street cars; decent performance but traction was limited, 12.90s to 14.00+ ETS...
