yeah 880 casting number is on the both sides of the block between the freez out plugs, and on the driver side rear of the block on the pad that the trans attaches to.
they are 1pc rear seal, roller cam motors.
you will need a special vortec tpi lower intake. i think edelbrock makes them. they are like 450 bucks though.
you can pick up air gap intakes real cheap for around 50-100 used.
factory rated at 260hp, 325-350tq or something like that. stock they run real strong.
i have a vortec block in my chevelle. has a voodo roller cam in it. you can use lt1 cams just have to push the down pin in.
if you plan to cam the motor, you must cut the spring pockets and retainer guides as the factory config is only good to .450ish lift.
good luck.
