Tim, here's the Post that was out of sequence, as you can see, I figured out #3

An update with Numbers, (I’m beginning to breathe again)
Casting date G 20 3 (Jul 20 1953)
Casting # 3701481 (’53 or ’53-’54) * ( see below) depending on which chart we go with.
Casting # on this eng is located between fuel pump & front of block. (1954 only?)
Cylinder head casting # 3836848 (1956)
Stamped serial # LAS394655
3 lumps cast iron between spark plugs, this eng has them. (53-63)
3 holes both sides of block, (drilled), this eng has them. (52-54)
Capt Bars are above the starter.
NO kidney bean shaped plate on drivers side.
Short passenger side plate.
4 screws valve cover.
Crank DOES turn.

*(Two) popular websites with “Eng Casting numbers & ID” charts show
slightly different years for my Casting #,
one shows ‘’54” and the other shows “53-54”.
Casting date was mid ’53 (G 20 3), I’m guessing it’s possible this engine
could have actually gone into a ’54..….

Three questions please,
1) any way to research that??
2) what do you believe I have?
Casting date says 53
Casting # location says 54
3) could someone help me decode the stamped serial # LAS394655
or steer me in the right direction to find it, I must be missing something
because I can’t find anything remotely close.
I’m new at this, so there’s a high probability I don’t what I’m talking about.

Jim
