Shooting the breeze. What’s the 1/4 mile time of a 340 challenger?

[kawahonda]

Question....i do not ant to cannibalize my current intake. I want to buy parts that I need, not just remove parts from my original one.

1) I suppose this is where the switch plug of some sort goes. Temperature switch, maybe? What's it called, or a link?

2) I need some sort of a adapter like the original for the water system that goes here. I think it's straight up. What's it called, or a link?

3) What thermostat is recommended? 180F?

4) (not pictured), I need a brass inlet fitting for my carb. Does anyone know off-hand what the size is? There's two to pick from:

@MoparDave will have everything you need with the exception of he carb fitting. He may have that also.

You need a temperature sending unit. That's the small threaded hole.
Heater hose nipple. The larger threaded hole.
Thermostat housing is straight.
Thermostat is always subject to opinion. I will just say I run a 160 in my motors.

Yep, Dave is rounding me up some items as we speak!

I got in contact with Mike, and it sounds like what's in his kit is a "flange gasket" and not a "phenolic" spacer. He said the flange gasket is 11/32"....not sure when a gasket becomes a spacer, but I've always considered it a spacer...

Because it's always a good idea to have some insulation under a carb for heat soak issues, even with an LD340 with blocked cross-overs, what would you guys recommend for my "aux" LD-340 Carter 440 AVS setup that I'm building on the bench right now? I'm thinking a 1/2" Edelbrock wood spacer may be a nice little thing to add.

divided:

open:

or four-hole:

Would be nice to start using studs too, which are included.

Or save my money and just re-use the "flange" gasket from Mike's set...

I'd imagine I'd have enough hood clearance for a 1/2" "Phenolic spacer"...

I just put the Edelbrock 9622 between my new AVS2 and RPM Air Gap.  It's only 5/16" thick and acts as it's own gasket.  Too soon to tell but I like it so far.
For a dual plane intake on the street in a stockish motor, I want the divided type.  If you were trying to add more top end and had the cam to support it, the open type may help.

Hmm. I'm a bit torn between what you got vs maybe the divided wooden spacer.

My car was exhibiting some very hard to start issues while hot yesterday. I wonder if my Mike's carb gasket isn't really insulating very well. Wood is definitely the best.

[kawahonda]

Check out we've done on this AVS.

[worthywads]

Looks like a standard plumbing pipe fitting for the heater hose on the front of the manifold, not a barbed end.  Or has that been covered?

[kawahonda]

We still need to get that off....I need to get some penetrating oil at this point.

The smaller heat hose fitting that Dave sent doesn't work. Need to figure that one out as well.

[kawahonda]

I'm assuming I should plug the vacuum nipple on the electric choke housing as well........

I backed my initial down to 15. I was tired of the intermittent pinging at >16. In the future, I will try 16 but for now, the car sounds very happy.

Today, my Challenger has graduated. Finally broke in the rear-end. two-tire frier w/ Doctor Diff. After 500 miles, I can finally get myself in trouble.

Sorry for the weak-shift into second...I think I only shifted at 4k, but at 5k or above she will definitely chirp into second. Speed limit is only 20 MPH here, but it's remote. Still, gotta play by the rules....find a wide open road.

I "feels" like a high 14 car. I don't seem traction limited....yet.

Now the journey begins to lop off a second. But first, some aethestics work.

The tire marks in the video are not these...this was my first attempt on a fresh lubed rear-end. Looks like she's workin'

I've been really focused in on Mopars in car shows over past 3 months...

Nothing beats a near-stock looking engine with the original radiator and the rest of the works. I saw a 340 today that just about knocked me out...factory overspray on heat-shield....but also...an LD340...

The LD340 does not detract from originality a single bit! The LD340 in-fact has a history of it's own...that isn't very well documented.

Hopefully I will continue to make the right choices. My goal is to make a 340 that looks just like a 340 from the factory!

Congrats !!
Cool that you have it working well

The LD is respected by us old guys that remember them back in the day. I also like the DP4B and the CH4B on the B-engines for the old time look. I think the B engine manifolds were a bigger upgrade as the stock small block manifold was pretty good.
