    Ok, Dumb question maybe, But what did you look at to tell? I was kinda going by what I could see of the exhaust manifold and spark plug locations....

    Look at the valve cover, a big block has a wider cover. also the small block has 4 bolts holding it on, 2 on top 2 on the bottom. the valve covers on a big block have 3 bolts on the top and 4 on the bottom.
    a big block also has a by-pass line from the intake manifold to the water pump.

    Aren't the bbc exhaust ports evenly spaced whereas on a sbc the center ports are next to each other?

    correct, til you get into the newer style small blocks they went to staggered valves like the big blocks.

    Except on a 427, it has the same size valve covers as a SBC, not sure about the number of bolts though......

    Man that's a new one on me. Every 427 I have ever seen has the same size valve cover as the 454, 396, etc. Where did you see one with small block size valvecovers ?

    That would be my thought, isnt a 427 just a 396 with a 454 crank? or something along those lines. It should look more or less the same as any other BB depending on the heads, etc thats on there.

    You are close, but it is just the oposite. A 427 is a 454 block with a 396 crank if you want to look at it that way.

    Small Block, Look at the Exhaust Manifold. Center Dump for #s, 4 and 6. No 427"s don"t have the same size Covers as a Smallblock!
    As a Chevrolet Certified Technician, since the Dawn of time, I can Vouch for this.

    If you get the info on the right front bank in front of the head, you, can go to this web page and id it. http://www.nastyz28.com/decode.html this guy has alot of info on Chevy engines. I went through about 2 reams of printer paper just copying the info for the trips to the boneyards. With this info I pick up a 300 hp 350 ci corvette motor for $100.00. The guy is good.

    L8r,

    No dice. Maybe you saw a 427 small block. It's bored & stroked like a mutha. But a 427 BB is a canted valve motor as is a 396-402-454-502 ect...
