L-Code vs. K-Code 440

[R413]

those 68-69 C-body body HP manifolds like you have pictured are not hard to find, 2863409, same 383 and 440.

the right side HP is the same as B body.

A 727 and a 18 spline Dana car.

I guess @Albert Spangler has perused my collection and disagrees.

A friends Dad had a 69 Chrysler station wagon with a 383 that had the magnum exhaust manifolds from the factory. That big wagon was pretty fast when he took it out one night..... LOL

A friend of mine had a 197"X" (1970s but don't remember what year) Ford Station Wagon with a 429 4bbl..We called it "The Raggin' Wagon" because he drove the crap out of it. One Mardi Gras morning he picked me up and on the way to "the festivities" he jumped the car up on a 45° grass levee and we rode the side for a couple of blocks.
I am blessed to have survived my teens and 20s...

I know this thread has been dead for awhile but I am still trying to understand, and not having much luck searching is the L Code HP? and K Code Non HP? Or did Chrysler just change the letters for different cars for the heck of it?

In 1969, what was the difference between a L-Code vs. a K-code 440?

How was the high-performance 440 different than the regular 440?

Did the L-code come standard on any cars, or was it just an option?

As I recall L code 440 was Standard in GTX and R/T also Chrysler 300

Here's a 383 HP in a 68 Polara 500. I'd hate to try to locate one of those manifolds.

Here is one for you, same 68-69 version. 2863409 casting #

The K and L code 440 VIN letters were only use on 1967-1969 cars. For 1970 they changed to T for standard 440 and U for HP.

Ok so only from 1967 through 1969 but does L mean HP and K mean non HP?

L is HP. K 350HP

L is HP. K 350HP

Great thank you!

Yes. The introduction of the higher lift cam profile in the '67 440 upped the horsepower specs and therefore a different assembly number, sales code and VIN indicator. The HP stamping is a helpful exterior indicator as to what is inside during engine assembly and installation.
