Maybe he needs a good 6 Pack intake? Just a thought?
I think I could use a good 6 pack after reading these last few responses. I got what RRR was trying to say right away.
LOL

Don't forget the hardened rod..
Why is the ld340 never in intake shoot outs. Are they scared of it? Same with the weiand excellorator.
Welcome back MikeIf you look closely the ld340 is ported a little different on a couple of the rearward ports works the same though.
As title says. I’m curious how they compare to the new Eddy RPM and Airgap. What are they worth these days?
I got Pictures. Lol

Your right unless your trying to extract every last pony.I have tested the LD340 on small port heads. The reversion thingy is crap. Ur motor is an air pump. The heads are doing the sucking, so to speak. The 318 actually picked up a few ponies and tq. The only way u will get reversion is if u have a hood scoop sealed to the carb. Kim
Don't likely use an LD340 in testing as it's not available new. The Mags are about selling product for manufactures.
The Performer 318/360 is a solid intake with about 5 minutes per port and a grinder. Run it and a 1" spacer and it runs VERY close to an RPM/LD340 intake. BTDT. If you have the intake, it's capable with a little elbow grease.
The port opening is a non event with these intakes between the LD4b, LD340, RPM and air gap.
It made 17.5 HP over the stock factory intake. Made power to 6400 rpms but I think I did not have enough spring. Everything stock less the cam(stock lift values) and 1 5/8 header.It's the 318's version of the LD340. Separate intakes for the designated purposes.
Kim, have you tried the LD4B on the big port heads?I have tested the LD340 on small port heads. The reversion thingy is crap. Ur motor is an air pump. The heads are doing the sucking, so to speak.

I bookmarked this post Kim. Great real world information!Yes, I have. 1 weekend at a test and tune along with at street class I changed 6 intakes. On my 1970 340 with the 284/484 purple shaft cam. 67 dart with 1 5/8 headers and 3.91 gears. Factory 340 high stall converter. The Torker 340 was the worst single plane. The Holley street dominator was 2nd. The Weiand Excellerator was the best. The LD340 was the best. The LD4B Was a close 2nd along with the Weiand 7507 I used the stock iron intake as a base line. The same carb was use on all the tests. 750 Carter Competition Series. 6000 rpm redline. It was all pretty much a wash as what the single planes lost on the bottom end the made up on the top end except for the Torker 340. It was almost 2 tenths slower. Kim
