It didn't work I have never heard anyone that like them unless they had switch from a two barrel to the Streetmaster witha four barrel Almost all of the stock cast iron four barrel intakes and carbs have more power and better milage than the same carb on a Streetmaster intake, regardless of brand and type V8 motor There a bunch of better intakes out there Mr.Cab Racing and winning with Mopars since 1964.

NOT for any power-gains .. but for MPG and street-manners ... TWO BIG

The price was right though, it came with a 600 carter I bought for $40 18 years ago.

That's correct, LD4B is a smaller version of the LD340. Nearly as good as the LD340 also. The LD4B for some reason has reversed runners from the layout on the LD340, and the ports are sized to match 318 heads, and for some reason there is no provision on the LD4B to mount the coil (the cast boss is missing).

It's low-mid RPM where this intake shines at high RPM it's no big deal. Take care, Rick 68 Coronet R/T 440 & 68 Charger 528 Hemi,and 5 Challengers! 6 cyl, 318, 360, 383, 451

If so I'll look for something as that is what I have (w 1406 Eddy) & if it's hurting me that bad & I dont know it I'll keep my eyes peeled for a cheap dual plane 2 of the cars I ran it on were daily driver MPG type builds, one was a 74 318 valiant with 2.76's and the other was a d150 shortbed with a 318/998 and 3.21's, on the valiant I switched to a sp2p with the same 600 carter and the d150 got a performer with a edelbrock 1400 600cfm carb. The truck picked up 2 more mpg with 3.55's, small hooker headers and 2.25" duals and a really small crane hyd roller that was sold as an emissions legal cam, it already had #302 heads on it so I left them alone.
