The majority of the 340 Stock Eliminator cars anymore are capable of running
well into the 10's with stock manifolds with either AVS or Thermoquads.
A few have been in high 9's running the production Carbs and stock compression
ratio and stock lift camshafts (.462/.473).

Yeah, the fact that 340 stock eliminator cars run that fast is amazing !

First picture,This would be a replacement for the factory intake. Exactly the same but aluminum. I have it bolted on a plastic mock up engine in the second picture because its light and is the same dimensions as a factory cast iron intake. It has all the same hose and sending unit outlets and even the choke tub.
The LD340 would be the same but it does not have the choke tub built in.

Second intake choice A Wieand is another good intake seen in the third picture on the engine painted orange.

An Air gap seen on the forth and fifth picture we had to cut the hood braces for the factory air cleaner. seen in the forth picture

Sixth picture is a holley strip dominator. This also needs hood trim for the factory air cleaner.

You can get away with the taller intake if you use a low profile aftermarket air filter base. That is what we use to make the air cleaner on the seventh and eighth pictures for the Indy intake which is the highest . And it still sealed tight against the hood after trimming the braces.

Last picture is another Air Gap on a 67 Barracuda. It fit under the hood using the 69 and earlier air cleaner but tight. The car has steel motor mounts. If they were rubber it would bounce off the hood

Would you happen to have the part number for this intake?

Thanks,

I really wanted to go with a Performer RPM, but he doesn't want to change his choke setup on the AVS he runs.

So I guess that leaves me looking for a Mopar aluminum dual plane. No good deed goes unpunished.

Choke ? You don't need no stinking choke ? Slap the RPM on and wire the choke open, or just remove it !!!! Great intake, thank me later. :)

I took choke off mine decades ago. One less thing to break and fiddle with. Even in the coldest weather once it idles for a few minutes, not even warmed, up its fine.

Tom,
Part #P4529116
Number cast into bottom of the intake is P4532059.
If you see someone selling it claiming the casting number is the PN, it's probably what you're looking for.
 
Thanks, Now that I know what to look for it's time to post a wanted ad for one of the earlier version intakes.

I removed my choke linkage. Also epoxied aluminum rod in the shaft holes and blended.
