Greetings!

I picked up a 350 and I'm trying to decode it.

Cast 5.7 LG SGI
Stamp V0619TPD

What is a TPD? I can't find a reference for this anywhere...

Thanks.

Could it be TRD? That is a 350.

Not likely, because the casting on the block is 5.7 LG SGI, which (if I've followed the trail properly) is late 80's - early 90's 350, so a 1972 stamp wouldn't seem to make sense...

Is it a one piece rear main seal? What's the casting date and part number on the block?

that would be a 6.

Right

Well, it's clearly not a six. The cast "14093638" is 1987-1995, 350 cid, Car & Truck, 2 & 4-bolt main, Passenger, 1-piece seal. It also has GM 5.7LG and underneath that is SGI. The "TPD" in the stamp below is just a mystery...
