Hey all;
I have come to the general public to help me decide the next step of my build up. You see, I wouldn't mind an experiment to help out those doing simular build ups. PRO and I both have the MoPar short block ( P4876908, the 10-1 pre magnum block.) and Edelbrock RPM heads. (unported) (correct PRO?) My car is a '73 Cuda, 4spd with a 4.10 , 8 3/4 rear. Headers are Hooker super comps with a 2 1/2 exhaust. ( they dont fit with the lakewood bellhouseing.) I'm interested in what intake should be tryed. Pro has an LD-340 uptop his combo. I have one also. So as in the intrest of knowlage and discovery, and yours to, which of the following intakes should I try? I will be using a Carter 625 and 750 for comparisions. #1 A Torker II #2 A RPM Air-gap #3 A Bone stock cast iron '79, 4bbl intake |

Have you modified your LD 340?
If not do it!!!Works, Is this for Street use,Street/Strip or what? |

Hi
Well, my opinion is that you can count those two old designs out, namely stock and Torker II. RPM is better than Torker even though one plane intake manifolds are thought to be good but Torker II has got small runners compared to RPM, right? And I don´t see any point in using a restrictive stock cast iron manifold in your healthy combo. So I think the choice is between your current manifold and RPM. I personally like RPM stuff but I don´t think there is anything wrong with your current manifold, though. How fast is your ´Cuda now, by the way? Just my 2 cents, - BB70Challenge |

Yes, it's modified. The center divider is milled and rounded off. Thats it. BB70 Challenger; No real current manifold. The torker II's runners look about the same size as the LD-340's or the RPM Air-gap. No ruler insight. (Do ya really want to know?) Have not run the track since it was a 318. It's an orignal 340 car. But I got it with a 318. Hoped it up to a mid 13 second car, all day everyday. I think PRO ran 12.2 or .02 in the 1 1/4 with his combo. I believe its a 3200lb car , 4spd and 3.91 gears. Correct me if I'm wrong PRO. Now vote all you readers. |

Yes rumblefish,the heads are unported,I would have them ported but its only good for 30 ponies for $900,also it ran 12.02 in race trim on pump gas,also my LD340 is STOCK with a 1" open spacer,I wont modify it because it has tons of bottom end,from roll it will break em loose at 2200rpms,it has so much midrange it feels like a big block,and it has so much top end it pulls to 7000rpms easily,it easily outperforms my tunnelram it does have a 2" section missing out of the divider but Im sure thats stock.Id use the 750 edelbrock Rumblefish for sure Ive had one on my car but it doesnt compare to the Holley 800 dbl pumper I run,its prob 35-40hp less than the holley,Id try the 800 edelbrock if I was stuck on them..........PRO.......

The LD-340 should have a divider in full. I milled it away. It was full to the top. Also, I forgot to say, someone here said that they were a square bore from the factory. Not this one. It takes a big T-Q on top with no problems.
I don't have anymore holleys. Well one. Currently in stock is a spreadbore 4011 or was it a 4010? Its a 650 model. I don't like how the primary choke plate is just wedged in the shaft. Sad if ya ask me. Also, a old AFB I picked up for parts for the T-Q that came off a 440. Once thats set up, its gettin a try. Just for fun. I have only spread bore spacers @ 1/2 thick I think and a 4 of the MoPar 1/4 T-Q spacers. Whats your take on an intake? Like I said, I'm game. |

Mopar M1 ??
Have any of you guys had any experiences with the Mopar M1 dual plane?
I have been looking at getting one of these for a similar 360, although a litle milder, setup to rumblefish. It looks like similar in style to the RPM. Are these manifolds bad news? I am suprised no one has mentioned it yet. David Thomson |

well i also have the ld340 intake on my challenger.
the next one that i would like to try is the rpm air gap so (Just do it) |

The Performer RPM has been getting good reviews in some of the Mopar magazines, but the articles I read were on the 440, not the 360.
The Mopar M1 single plane also seems to work really good. I don't know about the Torquer II intake. I have a new Torquer II 360 intake I bought for a project that got put off because I built the 451 stroker. Someday I may have to built that 360 and try it out. |

LD 340 and Performer rpm are definitely the best but I would bet they'd turn identical times. I run the rpm but if you've already got the LD 340 you're all set! You'll hate a single plane on a street car and as far as M1 intakes go you might have to buy 20 of them and try to find one without a core shift. I tried a victor 340, it sucked, theres a guy at the track with a heavy 73 R.R. with a dual plane Weiand stealth that runs high elevens with front wheels off the ground. Can you tell I like dual planes!!!

how about the Air Gap?
Have any of you guys tried and liked the Air Gap, is it worth the extra $$. How is it compared to an rpm or performer?

We have a 340 dart we switched from victor340 to performer rpm air gap and the motor really woke up!
If your motors mild the performer is fine but if its a little more modified go with the rpm, I would not switch from rpm to rpm air gap, for the money they'd probably run identical. |

RPM Air-gap installed! Now I just need time to the track.

Thanks 71sacmp;
I'll have to take a personal day to make the track. Work afternoons on the weekends. Let me get some breakin miles on the beast first. I'll report back when I get there. |

One of the Mopar Magazines just did a test like this. I'll see if I can find it, but the Edelbrock RPM really performed good, while the Torker made slightly more peak power, but not near the torque.
Rember that the dual plane intake will like (need) a larger carb than the single plane. I don't know if they tested a Mopar M1. I really haven't seen much on the M1 dual plane as I think it is more torque designed. I think it may fall somewhere in between the original Performer and Performer RPM? The Mopar M1 single plane does work really good in the track cars I have seen using the 292/0.509" and larger cams. |

Manifold choice
With those tall gears, I'd try a single-plane to make the best use of those Eddie ports.

Panic; nice to see you here. Nice page (s) you have there. To all, check'em out.
Jimms451, YA! tell me witch Mag did the test. Should be interesting. It should be noted this post was more for fun as in the stock 4bbl manifold choice. (If you didn't giggle on that on, check funny bone) and this car is a streetbound ride. Anybody out there with this combo and running a torker II? How about the stock dual plane |

Guy's check out the August 2001 issue of mopar muscle. They did a dyno shootout between the Performer, RPM Air Gap, Mopar/Holley six pack, torkerII, And a strip dominator. Done on a 360 with an out of the box 770 Avenger holley. It was basically hands down all around winner for the air gap. The 2nd spot with all around performance was the 30 year old technology six pack.

I put the RPM on my 383 and it woke it up. So much that the 750 edlebrock wouldn't feed it. Had to take the Holley off ny truck to make the car run on top. Don't loke edelbrock carb's anyway! I highly recommend the RPM. Very good piece. I believe I read somewhere that it outflowed just about everything out there for the Mopars.

I'd be kinda interested in buying your stocker iron manifold. Would you please tell me the casting number, is it a spread bore, will you sell it, and, if so, how much??
Thanks from ...Doug GOD BLESS AMERICA!! |

I ran a M1 single plane in a '89 dakota 360. I topped it with a 650 holley. It was very streetable and had plenty of pulling power. It was a fun ride.

Hey RB I recently tried a Holley strip dominator(single plane)and it feels just like a torker except a little stronger up top,its definately a dog down low under 2500 but I think itll outrun the LD340 just because Im a 4 spd,also I just switched to 3.91s,Well be racing here as soon as the snow melts,3rd weekend in april,Ill let you know how it goes..........PRO.....

Yooooo! Pro;
I almost purchased that intake. Looks rockin. That might be the next intake I get. I figure I'll make use of these other intakes first. Given it's power band, it looks like it will really shine at the strip. A bit more than what I have set up now. I'm going to get back into the other 360 I have wraped up and fix whats wrong. Probly sell it after that. Right now I'm in contract on a house. Hope to close by March, in by May. Gotta hurry with the painting. Baby boy on the way. Due June 6th. Also, after looking at about 100+ house's, seriously, I found one with a 2 car garage (That's all I really wanted) as well as everything else "WE" wanted. Now, to furnishe the garage! I'll start with a hamock and TV in the corner, right over the fridge. You know, arms length. |

I'm putting the RPM Air Gap on the sailor Son's 360- '66 Barracuda. I read the shoot out referred to, and it looks like the Air Gap is the neat piece... for now.
