440 engine code need decoding

[Wollfen]

I have a 1978 440 motor here and the pad reads "8T 440 EHP". My best guess is the 8t is for 1978 and the EHP is for cast crank high performance? Anyone got a firm idea on this?

I think the T denotes a truck engine, not sure about the EHP. Does it have a 77 cast date....?

8T = 1978 (All 440's in 1978 were stamped 8T)

E = Cast Crank (All 1978 440's had cast cranks)

HP = High Performance

Hmm being a HP motor i guess it may be an ex cop car engine? i think I need to see if there is a VIN stamped in this thing now huh.

Has anyone seen an 8T engine with a 78 cast date......? A source told me there were no 440 castings in 78.... The 8T engines were carried over...

i think mine is a 78 casting eh? i will definitely check that out tomorrow.

On another note I found the number stamped into the pad in the side, it isnt a full VIN so I doubt i will ever trace what it came out of, the number is FA 223108.
I also found that the 452 heads have double valve springs in them too, this is a complete long motor and i am now contemplating selling it to help fund the projects. Would it be worth 400 bucks? It probably needs reringing and bearings etc, its all greased up and dirty right now and the heads are off.

I've seen Motorhome 440's with 78 casting dates.
