Default I can’t find a whole lot on my engine

What I can make out is GM 5.7l G
SGI 6
The next section up I think has G130 and the next has 14093638
I’m not finding many other numbers on it. I was to by the previous owner it was maybe a crate motor. It also has oil cooler lines coming from the oil filter block.

Everything you need to know about your engine is stamped on the front identification pad of the block. It will list (year, foundry were assembled, rated horsepower and displacement carburetor and transmission used) includes car partial VIN and date of assembly.

Block casting numbers tell you what it could be. Since you have a one piece rear main seal block cast after 1986 the displacement is cast right into the side of the block.

5.7 tells you it is a four inch bore block, and the stroke determines the displacement (Chevy only offered one crank stroke at 3.480" inches, but you could buy a 3.7500 inch stroke with new 0.030 over sized pistons to build a 383).

The only other option with a one piece rear main seal small block is a 5.0 liter or a 305 with a tiny 3.736" bore that a 2.02" valve would hit the edge of the block it is so tiny.

The numbers on the engine ID pad tell you how your 5.7 was built what it is out of and the other information I mentioned above.

Block casting numbers tell you what it could be. Since you have a one piece rear main seal block cast after 1986 the displacement is cast right into the side of the block.

5.7 tells you it is a four inch bore block, and the stroke determines the final displacement (Chevy only offered one crank stroke for this block at 3.480" inches you get a 350, but you could buy a 3.750 inch stroke crank, with new 0.030 over sized pistons to build a 383 cid motor).

The only other option with a one piece rear main seal small block was the 5.0 liter, or a 305 with it's tiny 3.736" bore. A bore so small that a 2.02" valve would hit the edge of the block on the way down when opening it is so tiny.

Thank you Dave it was hidden under a nice heavy coat of paint. I came up with V0316BMA.

BMK (can't find a BMA) comes back to a 1990 L98 235 horse 350 TBI out of a light truck with an automatic transmission.

Too out of focus to read any of that info. What is your question? If it is that the casting numbers reappear every ten years, then yes they do. Chevy makes over a million cars a year (some years nearly three million). That is a lot of small blocks and every ten years the casting numbers are recycled assigned to a different motor and you use the casting date to determine which block of casting numbers the block belongs to.

Today they cast the displacement on the side of the block, and glue on a paper bar code to keep track of the engine as it is assembled for use. Just think of the fun your grand children will have trying to figure where there engine came from fifty years in the future when the only thing they can find is a hot glue spot with one or two lines on it.

Long story short I need a fuel push rod for my mechanical pump but don’t know what type of cam I have to know what rod to get.

Unless it is a billet steel custom ground can (and few of those engines retain a stock mechanical fuel pump) you use a stock fuel pump rod made out of mild steel to ride on your cast iron cam elliptic. Since your engine was out of an EFI truck it won't have the rod installed (nor a bushing or a machined hole in the crank to support a manual trans). The truck it came out of had a low pressure electric fuel pump in the tank (17 psi for TBI; 48 psi for port injection).
