If it came with the vehicle you can call a GM dealer and give them your vin number.
If your just buying a used engine you will block casting numbers on the front and rear of the block. Again you can call a GM dealer and give them the block casting number and they can tell you everything you might want to know. On the driver side behind the valve cover you should find the casting numbers. You might have to clean or even wire brush it to be able to read the numbers. On the front it should be like behind the water pump and again. You might have to clean and or wire brush it to be able to read the numbers. I hope this helps you out.

I have a 97 GMC 350 vortec that the starter motor kicks back. Its been at the locl shop know for a week Figured I'd research it a little


what exactly do you mean by "kicks back"
IN all engines if the engine fires hard against the rotation of the starter motor, it indicates that the ignition timing is way too far advanced
GM products are around the 10 -12 DEgrees BTDC static timing and any thing over that will cause problems
If the timing is right then I would be considering replacing the crank position sensor and/or the ignition control module

Does a 97 Isuzu Hombre have an interference Engine?


great question but guess what, you failed to say what engine?
in usa? if not what country?
gas engine or diesel.?
some USA engines in this car are GM 4.3. Vortec
the GM L35 or GM LF6 engines, both are V6
if in USA, the VIN number tells you what engine is really there.
better is the EPA underhood sticker shows real engine name,
if GM it uses the 3 digit GM name for engine.
with that fact we can google and find out what it is.

Will not start.


The "spider" up under the plastic intake plenm, the poppets athe end of each of the plastic tubes that supply the fuel to the cylinders get carbon on them and cant spray fuel. to buy a new one at GM its $550.00 Gm is the oly place you should look for one no matter the price aftermarket "copies" are not the same and while you are in there change the fuel prssure regulator at the sam time they are bot a big problem with the vortec
Change the fuel filte also and then EVERY EVERY 15,000 mles and don't worry about the engine oil change that once every 4 or 5 years that is not nearly as important as the fuel filter nothing will happen just remember the fuel filter and forget oil changes don't worry about all that 3000 mile stuff.
