Would anyone have some good pictures of the correct exhaust manifolds used on a 340 in a 71 E body. Am I thinking correct that the 71 E body 340 used different manifolds than 70. Also, did the 340 A body cars use the 70 manifolds in 71?

Thanks
Dan

1971 340 A-body cars used the 68-71 style on the drivers side only (casting# 2863553), the passenger side was a new for 71 casting with a center dump design (casting# 3418623).

1971 E-body cars used a new for 71 drivers side which was a log style design with a rear dump (casting# 3418621), and the passenger side was the same new for 71 center dump design the A-body used (casting# 3418623).
.

Confused yet?

Ahh, yes. But not as bad as some others . I have seen 71 E bodies with 70 style manifolds that the owner will swear are original.
I had myself convinced there was maybe a change over date. I have an original late 71 engine with a set of original manifolds, and they look nothing like a 70.

Thanks!

71 340s are a pita to detail. so many mid year changes. I suppoe its possible that some early 71's received 70 surplus manifolds. I think a lot of people use the 70 on a 71 because they look a lot nicer then claim it to be original.

It's a poor picture, but I do have a shot of the 71 passenger side. This car had a build date of Nov 9 1970

There were a few pics in this thread '71 'Cuda engine

VERY unlikely, I'd say absalutely not short of a pilot car or some other pre-production oddball.

Hammer hits nail on head

I have no idea of the build date or the vin.
But friend of mine used to own a gold '71 cuda 340 vert, gold with white interior.

He bought it off the original owner, whom also happend to own the dealership it sold new at btw.
I'm also pretty sure The car was still original paint and unrestored when he had / sold it.

And I am pretty sure it had the 70 style manifolds on it.

Last I heard Tom Lembeck owns the car now

Which probably means it very well could have recieved some dealer upgrades/changes.

At any rate it would be interesting to see the complete history/details on the car

I used to own an early production '71 340 Challenger, now owned by another board member - Aug 2/70 SPD and it was equipped with the log-style 340 manifolds.

That car's twin, 1 digit later in the VIN also has the log style manifolds.

VINs began with JH23H1B1001xx so they were about as early as you get and had other '70 style sheetmetal.

I have had other September and November '70 built '71 340 E-bodies and they all had the logs.

While it's never say never with Chrysler, at best I could see an A-body '71 340 making it into an E-body and that would give you the high-rise manifold on the driver's side.

Otherwise, IMHO there were too many changes between the '70 and '71 340 such as intake, carb, distributor, solenoid, crank breather etc. that a leftover '70 engine getting installed would be unlikely.

Yes - And the other big thing would be the different head-pipes that go with the manifolds....a car would have to be co-ordinated to have the new style manifolds and pipes....fine for Clairpointe - not so much for an assembly line.
