Stupid Quest. But Cant find an Answer

Ok guys I know this is not a Supercharger question but i cant seem to find the answer on the net. I am planning on buying a 331 stroker motor and want to know what the difference between a long block and a complete engine is. So far all i know is there is about a 1700 dollar differance in an ad in my 5.0 Mustang Mag.
Also I am thinking about selling my Novi 1000 kit and was wondering if anyone knows what they are going for used. Its almost new. I bought it in Dec. and it has about 500 miles on it.

years ago when I was even more younger than I really am now, me and pop bought an advertised BB Chevy "long block."

It was an assembled short block with heads. no more.

Complete was just that. I remember seeing a GM Goodwrench 5.7 advertised as complete, and I remember it had pretty much everything..valve covers, too. No alternator, electrics (did have a distributor) but I can't remember if it had a water pump.

long block is with heads, cam. no valve covers, intake setup, distributor, any accessories, balancer etc. complete is more intake to pan. but you still dont' get everything!

You're best bet is to contact each vendor and ask what exactly their longblock or whatever terminology they use consists of, that way you get no surprises.

thanks for the info everyone
