what engine? Rule of thumb for an engine with cast block and aluminum head is 45 ft lb for the big ends, 55 for the main bearings, 55 - 65 for the cylinder head. Camshaft 35 - 40.
Your question on the other hand may refer to finding the output torque of the engine, in other words the power that is put out to the transmission train which needs to be determined on specialized equipment. Please be more specific.

"You need to get the suffix code off the front pass side, on pad in front of the head. It will be a code thats 6, 7 or 8 digits long. The 1st one will be a letter, next 4 will ne bumbers and last 1, 2, or 3 will be letters.. Like say V0621KH. V0621 if the prefix which tells plant, mo. and day, KH would be the suffix code which tells engine size, HP, induction system, and car it was used in Your 3858180 is not a vin #, it's the casting number and no it does not decode as a corvette. The casting # does not tell what car it was installed in. Its just the size and year range. That # is added before the engine was ever thought of being built and installed. 3858180....327...1964-67...2 bolt main thats all the casting number decodes as."

What kind of Pontiac engine you have? Is it pre-80's? Pontiac engines have a 2 letter stamp on the front top passenger corner of the engine block. The year is usually next to the distributer hole, and the actual casting number is located on the top rear of block. Some sites offer casting number searches. A good one is wallaceracing.com. They deal with everything from block and cylinder head numbers. If the engine is 1970 or newer, engine size is casted behind the dipstick passenger side of block and also on the front driverside of block too. There are many different variations of codes to list. A example it the engine is made in 1967, casting number is 9786133, code on the right front of block says YE, then it's a 1967 400, that originally had a automatic transmission connected to it, had 10.5 to 1 compression, #066 camshaft, 143 or 061 cylinder heads, 4bbl carb, and 325 horsepower.

Engine numbers are cast into the block, with all manufacturers finding new ways to hide them. Typically you can find the number on the rear of the engine ( the hardest place to look). The cylinder head also has a cast number on it and those are usually easier to find, commonly being on 1 of the vertical sides or end, although sometimes it is hidden under the valve cover. The head casting should help to ID the engine manufacture date, if that is what you're after. Spraying a rag with carb cleaner and wiping down possible locations will help to highlight the cast number you re looking for. Not all mfrs used cast numbers - some use punch pins to indent the number in the same basic locations and the carb cleaner will help to find those too.

I think the code explains it.
If you want to know what is it and were is it ,post more details of your car ( VIN , production date(p/d usualy found on center post below lock latch or on the driver door below lock mechanism-big information lable) and engine code(found on cyllinder head , frt. of engine , look from top- small polished cast appendix , even with bottom of valve cover , with three letters AVH, AHA , ABK etc...... )

Remove coil pack (1 per side) and marked cyl 135 on one head and 246 on the other, long strip about 2 inches wide and 10 inches long all cast epoxy. At the very back there is a connector plugged into each. This is only on 00 and 01 Cats.

It's in between the valve covers. On the passenger side, you will see it right below the fuel lines where they connect to the engine bracket. On the drivers side, you need to remove the flat strip that carries the wiring to the engine computer. There are 3 vacuum lines clipped to the strip. Take that off and you will see the 135 coil pack. 2 torx bolts hold each one.

the block casting when you are looking at the rear of the engine would be where the bellhousing bolts to the engine on the top-left side of the engine, the head casting should be on the left side head when looking from the back torwards the middle-bottom,and the crank cast should be behind the flywheel on the engine

I'm having a similar problem with my 2001 Saturn SL-2. My mechanic says this is due to a manufacturing defect in the cylinder casting. He says my cylinder looks like swiss cheese. If is affecting my fuel flow and, caused a small coolant leak into the head gasket. The only cure is to purchase a brand new head cylinder and replace. Estimated cost; $1,600.
