440 top pad decode

what say you?

Well January 20 seems to be the assembly date...But did they skip the "I" year like they do in VIN's? If not does the M make it 1977? If they skip the "I" then my guess is 1976 EAD.

Lc is that Low Compression?

Is this a trick question? I’ve never seen a post that Dan did not know the answer. Lol. My best quess is an over the counter block. Idk.

here's the 440's casting date & another engine with a similar font top pad stamping

High Compression 426 Water Tested

Jan 3rd 1964?

the top one 67 cast date and Jan 20th D=68 assembly date?

I got lost with this one, seems to have taken a turn at Hemi Street and I missed that turn. Where are we now?

I believe:

M = marine
440 = cu.in.
L = left hand rotation
1-20 = engine assembly date 1/20/68 (3*23*67 block cast date)
D = 1968 model year

sideways "0" & little "c"

the Marysville, MI engine assembly plant was Chrysler Marine & also built Max Wedge & HEMI passenger car engines (similar top pad font & layout) this 440 was one of a pair, the other being right hand rotation - I'm trying to track that engine down to get a pic of the top pad.

Dan was that the normal EAD pad layout for all marine engines? Didn't Chrysler also make 440 engines for commercial applications and did those engines have a different assembly date pad layout than an automobile engine???

I'm not sure - it's the first Chrysler built big block "MARINE" engine I've seen the pad on

& not sure how the industrial engines are stamped

Dan great information!
