Need help decoding my 427

[DM69SS]

I have a 427 and can't figure out what it came from. It is a 3963512 block. 4 bolt mains. High dist boss. Casting date of L 30 8 (on the side). Now for the confusing part - the code stamped on the front is T03257BL. It is standard bore and has the factory broach marks. I doubt it has ever been played with as I bought it from a guy who tore it out and down from his race car in 1971 when he totaled the car. I don't know if the internals are original, but they are apparantly L88 internals. High dome pistons, 7115 crank, 7/16 dimple rods with green overspray. Can anybody shed some light on this? I have scoured for a couple days through my books and the internet with no luck. If you need pic, I can take some later when I get home from work.

Our you sure the #s are T03257BL ?

Yep, I am sure of it. I've checked it over about 100 times. The stamp is really clear, so I'm not guessing at anything. I'll post a pic of it in a couple hours.

Odd.
There is an LB suffix for a 1969 427/335HP Passenger w/Man. trans. application.
That 7 is out of character..
