That is the assembly line engine ID stamping not the block casting number. It tells you what plant the engine was made in what date it was built and what application it belongs to.

UPB is the application the engine was used in. I don't have any of my books at work or I would look it up for you. I'm sure there is an online source that will list the engine ID codes you need.

The casting number of the block is on the top of the bellhousing flange at the back of the block on the driver side just below the cylinder head.

14088548 is the number on the back of the engine i can find that online but its vag says like 84-94 i know its out of a 80 somthin plow truck thanks alot for your help

Pretty much a 350 block is a 350 block.

Your only upgrades to the short block are if it has 4-bolt main caps or a steel crank. Many castings could be 2-bolt or 4-bolt blocks so the casting number alone will not tell you what it is. You have to pull the pan.

Heads are another story. You can get everything from 1.72 valve smog heads to 2.02 valve high performance heads and everything in between. Here the casting numbers will tell you everything.

Being a plow truck it probably has regular truck 1.94 valve heads on it that are good for about 330 to 340 hp.

ya just wanted to know the exact year cuz at 85 they made a slight casting change well thats what my engine teacher says and i know its a 4 bolt... just with my soon to be 383 build and the blocks needs to hold 450-500 horse and about 7000 rpms and id have to kill myself if it goes kaboom lol

some 350 blocks were made with a little better metal high tin high nickle which makes a little stronger steel. to find out if your block is this better metal it will be casted under the timing chain cover.

if its the better metal, whats it going to say?

pcwillsie · 10-24-2009, 12:35 AM

if I remember correctly it will have a +10 or t10 cast in it. I will look back in my notes and books to see if I can find it for sure.

the block will say 010 020 under the timing cover. i seriously doubt an 80's block is going to have high nickel. trying to turn 7k rpm the least of your worries is the block. you need a good crank rods and pistons. and an excellent balance job. with a 383 you shouldnt have to turn more than 6500rpm to get that hp. so long as the heads are up to the task
