Performance of 413 inline dual quads...good?

[Rolling Thunder]

I've got my '63 plymouth wagon and getting ready to pull out the worn out poly 318 and replace it with what should be a pretty stout early 413 with dual quad setup. I've seen a couple pics of guys cars on here with the early dual quads but have never seen or heard how they run...pretty good?

I know my car should be like a complete new animal with the transplant and cant wait to take it out after done but would like to hear from others with same setup how they like the inlines. Thanks.

My driveline is/will consist of the following:

'63 413 engine 10:1 compression, 282/292 cam, windage tray, factory cast iron dual inline intake w/pair of 500 cfm edelbrocks (setup and gone through for duals). Factory bb pushbutton trans, headers and 3.91 sure-grip rear.

Also, with what I will be running would it be recommended to upgrade to a mild stall converter? I was told the stock one would be okay but I have a reputable shop nearby that said they could make me one for the early trans that would be around a 2300 stall that would really make the car come alive??? BS or good advice?

Haven't done an inline dual quad setup so I'm no help there. But the stall you'll get out of any converter will be (partially) determined by how much motor you've got in front of it. Case in point. The original converter in my 69 383 Bee was probably a 2200 stall. However, I was pushing over 375hp at the wheels and it would go 2400 on the brake and flash to 2700. I could have used more, but it would have been a lot less drivable.

I tried the factory inline dual setup with the factory carbs back in the 80's on my 68 RR 383. The engine was a hot street build with 915 heads, ISKY cam 224 deg @.050 on a 108 LC. With the Torker and 700 DP Holley it ran 13.60's on street tires, 4 spd and 3.55's but the dual setup slowed it down to low 14's if I remember correctly, but no matter the exact ET it was noticeably slower and didn't have the punch. Thinking about it now I might have tried a different cam maybe with a longer LC to broaden the power band. That cast iron intake is a divided plenum single plane with a small cross over passage so doesn't flow like the Torker. You may want to re-think your cam selection to something like a factory Magnum grind.

Oh, love the wagon by the way :clap:

Thanks...took it out to Monster Mopar today a little worse for wear. Found out pecan shells and tree sap take a toll on primer even with a cover on...a cheap one that is. I guess it still looked okay though, Rob Wolf from Mopar Collectors Guide stopped me and had me pull out on the track for some shots for the mag...was kinda embarrased how it looked with the stains on it. Maybe they wont show up in the pics.
