Ok well i have posted about this once before and i found that the vin on a tpi motor is on the back of driver side behind the heads. So i cant see it from the limited space i have in my s10 motor bay, so if the spots right where motor and tranny meet could i just cut a foot wide hole in floor board from in the cab and it'd be right there, then i could weld it next year when i learn to weld in ag class

 

Could you use a flashlight and an inspection mirror. I've had to go that route to find hidden numbers more then once.

 

i wish lol i heard about that a few times from all the time i have spent researching ways to tell, and the motor and tranny meet under the firewall where it goes from flat up top to a indented hump.
Anyways i know the head would tell me but im not experienced enough with enternal motor parts, but if i can get the rite spot to make the cut in floor id hopefully be able to read it lol. but basicaly i should cut it where the tranny meets the motor, and from the edge of driver side to about a foot to the passenger side rite?

Thanx

 

Are the numbers near valves in this picture ones that would help me verify my motor with it tells me the year or motor size, thanx

 

??? are those numbers in that picture going to be any help if i look at them on my engine or no

 

The VIN is on the pass front, NOT the driver rear. What is on the driver rear is the block casting numbers and maybe the engine size casting.
The VIN Its the same surface that the head is bolted to but it sticks out and you can see it from the top, if there is no acc bolted to the front of the motor.

 

wait what? Ok well i was talking and looking for casting number, but lol the vin will be alot more helpfull, but i have looked all over the motor and there isnt any numbers anywhere but i cant see in the back s unsure about those numbers, but basicaly the vin is behind the fan belt on passenger very front of block, because i have looked there and didnt see

 

And you may not see it if its been decked during a rebuild or covered in oil.

 

ok so there should be a plate with vin numbers behind my alternator, because thats what is on my passenger front side in front of my valve cover, but i tried looking behind the alternator and saw nothing but it was a tight look, so should i remove alternator and hope it's there, also i tried cutting my floor to see block number and im like 3 inches to far back to see it so the last 2 hours werent to fun, please help

 

ok well thanx but i just got it and its the 5.7liter tpi, i had to jack it up and take driver side tire off then it was rite there so i scrubed the grime off with a brush and it read gm 5.7l then it looked like the last letter which was hard to see said either g, or c maybe but ill have to keep cleanng it later to be sure, thanx

 

So does that last letter stand for the blocks year or something, and why do other people have really long casting numbers and mine just tells me what size it is? > thanx

 

Because you haven't posted the casting # yet.

It'll be a 6 to 8 digit #, kinda right next to the "5.7LG" cast into it. Rather like this (which doesn't have the corresponding "6.6" cast into it, unfortunately):

 

Wait so rite below where it says GM on my block there will be like 6 numbers under it or is it somwhere else n housing as i didnt see anything but the motor size

 

It will be right exactly where the picture shows. They're mass-produced; they do them all the same; yours is just like all the rest.
