the performer and the LD4B are basicly the same... the SP2P was a poor attempt at a 4 barrel man for emissions. use the LD4B pr Perf...

Wrong!!! There is a vast performance difference between the Performer and the LD4B intakes. Noooo comparison.

LD4b is most like the LD340 which is still one of the best intakes for the small block BTW.
A performer is more like the stock 340 intake only in aluminum

wrong...different plenum volume. different runners.
you will see a gain over the stock manifold with a performer.
the ld340 is a good intake.

May be i s some aplications but for the most part will give very little over the OEM cast iron intake other than a huge weight savings.

With my stock headed 318, with near stock compression, headers, warm cam and 650 Holley, would my Performer be the better package or should I try to find a LD4B?
Dont mean to hijack, but I think it is valubable info to the topic at hand.
2016 Ram 1500 Crew Cab: 5.7, 65RFE, 4.56 gears with locker, Hemifever tuned, AFE intake, 87mm throttle body, JBA headers, 3" Flowmaster exhaust, split to dual 2.5" exits. 13.57 best ET so far.

I just installed an LD4B on my 318 (302 casting heads with a mild port job and headers) along with an Edelbrock 600 cfm performer carb and I love it! Lots of bottom end grunt and the gas mileage is pretty good too.
Last weekend I did a 600 mile road trip from Edmonton to Kindersly Sask. and back in the 67 Coronet with 3:55 gears and got between 17 and 19 mpg at speeds between 70 and 80 mph. The lower mileage was heading into a considerable headwind too! Lots of runs up to and over 100 mph along the way so I'm sure I could have gotten much better mileage with a lighter foot but wheres the fun in that???
If you ever want to open the throttle for miles on end then take a trip to Saskatchewan ... LOL
I'll start a new thread with the pictures I took along the way, we had an awesome day and I want to do it again several times this summer.
I got my intake from Tony at Tonys Parts (Moparts sponsor) for $100 US and I believe he still had another one in stock.

In reference to replacing a stock 340 manifold with a Performer, that's a step backwards. The only benefit a performer has is weight reduction. Performer is a manifold designed for the 318 and smaller late model 360 runners. It's called a Performer 318/360 for a reason. The stock cast iron 340 square bore AVS or TQ manifolds are superior to a performer.
A Performer RPM or Air Gap is a whole different animal. Similar to an LD340 in characteristics.
Some LD340's have a Chrysler number cast in it, so an over the counter OEM maybe... The LD340 is one of the best manifolds ever for a SB mopar.
The OP asked about fuel economy. The performer or sp2p is a better choice in keeping velocity up than a LD4B.

Sorry overlooked that. Most people that I know that build and/or modify an engine for a hotrod put fuel mileage on the back burner. Even with the high fuel prices.
Clean it, if it's Dirty. Oil it, if it Squeaks.
But: Don't fix it, if it Works!

Wrong? Where did I say the plenums were the same? I said as compared to certain manifolds it was more like a stock unit.

Great info. If you were to quess, how would the LD340 compare to the Air Gap & the Six Pack manifold for approx HP & torque numbers?
