What did this 350 come from?

[HarryH3]

I've got a 350 in the garage that I picked up a while back just to mess with. I finally got around to taking it apart and now I'm trying to figure out what it might have come out of! Here's what I've found so far:

Castings marks say 5.7LG - Block is a 14093638, just your run-of-the-mill 87-95 350.

The heads are also pretty generic - 14102193, 87 and up.

It has a factory roller cam.

The odd thing is that the oil pan has a threaded bung, about 2 inches above the oil drain plug, and there is also baffle inside to help keep oil in the sump. The pan appears to be a GM factory part. Any ideas what this thing might have come out of????


Also, is there any way to ID the roller cam? I don't see a part number on it at all.

What's the suffix code?

I'd bet a "B" body. Road Master or Caprice or a Custom Cruiser. Corvette also used an oil level sensor. Thats what that bung is for.

roller cam not truck . and sump trap and sender = car like above. good to swap to your truck with the roller cam stuff .

What's the suffix code?

There's "SGI" under the 5.7LG casting mark.

Also LO32 to the right of that.

Up front, passenger side of engine, where head meets deck. Stamped in. Should be partial vin + 3 digit code. (maybe other stuff, but something like "CXX")

 

[HarryH3]

Hmm, even on close examination with a flashlight, I can't see any numbers stamped anywhere on the block.

It would be on top of the block just infront of the pass head.

 

[dyeager535]

Not sure why they have "4" shown twice, but the suffix code will be located where they show the upper 4. Mortec code locations

If the block has been decked, those numbers are probably gone. Also, I wouldn't be surprised if some crate motor/replacements didn't come with anything stamped there, although I know there are suffix codes for certain replacements.

Also, on the next page I believe they show an actual picture of the code location.

Found it after scraping off some surface rust. It's on top of the boss that is just above the pass side water pump opening. Last 3 letters are SAF.

BTW, any ideas on ID'ing the roller cam?

 

[dyeager535]

Apparently it's an L05 (185HP TBI 350) out of a '93 Impala or Roadmaster.

Cam ID: not sure if anyone is keeping tabs on them, from what I've seen they usually have numbers on them somewhere if stock.

You can bet in those vehicles and that HP rating, it's a torquey cam with no top end.

 

[HarryH3]

Thanks Dorian! I'll examine the cam more closely today and see if I can find any sort of markings on it.

 

[HarryH3]

I finally found the numbers. 155-CPC-BC-11 However, a Google search on that string comes up empty.
