Do you know where the engine was assembled? Might want to give them a call and ask their advice? They may have records also as to what they assembled parts wise. On my ford when I fired it up, I put a zinc additive to the oil, did the distributor pull, oil shaft drill spin to get oil moving and then fired it up. Mine had been sitting for three years or so if I recall. I have also started long sitting engines that were driven with no problems following what Tech has advised. The biggest concern would be the cam lobes and inadequate lubrication to them. There is two ways to go, one involves disassembly and new gasgets and reassembly( a bit of work) the other involves what has already been mentioned. I guess we can all get super paranoid over what to do at this stage. I find weighing my options, the pain factor and the risks involved usually directions my decission after reading all of the options presented. One good thing about a sbc is they are cheap to buy as a crate engine, so if you take option one and start it with the lubing process, and it toasts the cam and or lifters, you can replace them. Or option two a partial tear down, which if the engine is not installed is a lot easier than if it's connected to everything and ready to go, then get a good sbc engine manual for torque specs and go to town. I believe 15 years ago that graphite and or zinc would have been in most assembly lube, but some of the others on here would know for sure. It seems those lube are slick vs. gummy so might still be fine.
I've always given it the quick prelube and if the engine is spinning free with little resistance when I hand crank the crank shaft with a big ratchet or breaker bar, then crank it over as stated above and see how she goes. It it doesn't turn freely, I'd disassemble and try to see what is going on. My 2 cents worth.
