    General Engine Block Specifications
    While 6 different bore size blocks have been produced, the small block engine can be classified into 3 bore sizes and 3 main bearing sizes. 283 blocks (3.875" bore, 2.3" main), 302/327/350 blocks (4" bore, 2.3" or 2.45" mains), and 400 blocks (4.126", 2.65" mains). In 1968 the main bearing saddles were increased in size from 2.3" to 2.45".

    <st1:stockticker>CID</st1:stockticker> Year Bore Main Cap
    262 1975 3.671 2 bolt ONLY
    267 1979 - 81 3.500 2 bolt ONLY
    305 1976 - 96 3.736 2 bolt ONLY
    307 1968 - 73 3.875 2 bolt ONLY
    327 1968-69 4.001 (2.3" main) 2 bolt
    350 1968-88 4.001 (2.3" main) 2 bolt
    265 1994 4.001 (2.45" main) 2 bolt
    302 1968-69 4.001 (2.45" main) 4 bolt
    350 1968-96 4.001 (2.45" main) 4 bolt
    400 1970-72 4.126 (2.65" main) 4 bolt
    400 1973-80 4.126 (2.65" main) 2 bolt

    Notes: 2 bolt ONLY means just that,. otherwise 2 or 4 bolt can mean either design...

    Casting Date
    Small block casting date is located on driver side rear of block on flange forward of bellhousing. Big block on the right side of engine above the oil pan rails.
    Casting Date Example: E038 - (E = Month, 03 = Day, 8 = Last digit of model year (1978)).

    Month: A = Jan, B = Feb, C = Mar, D = Apr, E = May, F = Jun, G = July, H = Aug, I = Sep, J = Oct, K = Nov, L = Dec

    VIN Code Format
    The vin code format is stamped onto most engines. The format consists of divisional identification number, model year, assembly plant designation and vehicle serial or sequence number.
    In 68-69 model cars, the serial (VIN) number of the car the engine was installed in is stamped next to, or under the engine code ID.
    Starting in 1970, the serial number is stamped either above the oil filter, somewhere on the block pad (in front of the cylinder head), or on the transmission flange somewhere. Chevrolet issued technical service bulletins to indicate which engines were to recieve a vin stamp, so who knows what could have happend (or not happened).

    VIN code format Example: 13N100001
    (1 = Chevrolet, 3 = 1973, N = Norwood, 100001 = Production sequence of vehicle VIN

    hope this is useful
     
  3. Someone needs to move a copy of this to the tech section and save us from tripping all over the net every time someone wants to check out their block.

    Thanks for posting.

    +1. I don't know how many times I've posted links to casting numbers for someone who asked but having them all in one place in the tech section would make it a lot easier on everyone.
    I think I still have the cylinder head casting number list from Car Craft out of the 70's in the bottom of my tool box in a binder. I copied that years ago and referred to it time and again over the years.

    Dude, that list of numbers is all over the internet. I usually just google "Chevy casting number #########" and it comes right up. Try it!

    That's a nice list, but a little hard to sort through. If you're looking for vintage Chevy blocks, cranks, heads, intakes, exhaust manifolds and so on there's a story at this site about vintage parts services that probably have what you need. I got a nice 427 block and the matching heads for my Impala on the first try. Here's a link to the story.

    Hello all, i'm not sure if this is the proper place to post this but here goes.

    I was searching for some info on an engine I was given by a retired Navy friend. He had it in his garage forever and he himself inherited when a neighbor friend who was transferred to a new duty station overseas. I was told that the engine was a 350 chevy he wasn't to specific on anything else the engine had in it but only that it only had several thousand miles on it and the guy pulled it out to put a big block in his car (he thinks it was a camaro), he blamed it on the fact that he was an avid Ford fanatic.

    From a quick visual the engine has edelbrock elite series valve covers, edelbrock timing chain cover, edelbrock 800 cfm carb (looked up serial numbers), Edelbrock RPM Air Gap intake manifold, Roller rockers, StreetDampr, a two piece rear oil seal, a 7 quart Moroso oil pan, and cast iron vortec heads with the 062 casting numbers. I have not yet dug into the engine internals yet to do and measurements. From what i can tell the block was manufactured June 28th of either 76 or 86. There is a tag by the oil filter that says refurbished 198943. I'm not sure if that is a serial number or the date in which it was refurbished such as the 43rd block refurbished in 1989?? I'm just guessing here. Last but not least there is are no numbers stamped into the block pad on the front of the engine in front of the passenger cylinder head.

    Here is were i ran into a problem when running the block casing numbers. The casting numbers look like they have been tampered with and was wondering if anybody else has run across this before.

    I have posed pictures below for reference:

    Would anybody out there know what type of block this is, whether or not the casting numbers were monkeyed with, and such. Any help would be greatly appreciated. Thank you!

    Those 3 humps are the casting ID for Vortec heads. Look for 8 vertical intake bolts and centerbolt valve covers. He already mentioned the Vortecs and that mark confirms it.

    Or you can just go HERE:http://www.nastyz28.com/sbcmenu.php and save it to your favorites. It's even got casting #'s for stock pistons and camshafts. :)
