GM 5.0LG

[JMRamos]

I JUST GOT A V8 GM 5.0LG WITH THE NUMBER 14101074 ON THE INTAKE
Any help or spec's would be appreciated.

What do you want to know about the intake? That casting number will tell you nothing about the engine.

These are the numbers on the block, V0303UXS, CL4128922, G-20, H10-627, 638, 14093638, 5.7LG SGI

These are all the numbers on the block. Please help.

So, here's the short story on your block casting by the casting number;
"14093638 - 1987-1995 350 Car & Truck 2 & 4-bolt Passenger stick 1-piece seal"
:shock:

Not sure what you reference to "GM 5.0LG" is, but the engine is clearly a 350 cid, 5.7 Liter.
The 5 Liter GM engines were 302, or 305 cid, usually through the '80's and loaded down with pollution control stuff! :roll:

Hope this helps.

Sorry to jump in ... new to this forum and have a similar question.
I purchased a 1981 firebird that had its engine swapped from its original 6 cylinder to an 8 cylinder, but I have no information on the specs.
I'd love some help deciphering the numbers I have found on the block thus far:

1- Front Passenger side
a. V0505DDM
b. 1GR190199

2- Rear driver side:
a. GM 5.0LG
b. D286

Any help here will be most appreciated.

Thank you in advance.
