454 or 350 motor

[stavenman]

so my father works at a scrap yard and they bring in whole vehicles alot so last week he had a 76 burb come in with a 454/400 so he ripped the motor/tranny out and took it home for me to see if I wanted to use it.I dont know if I should have this motor rebuilt or just get a 350 from his work and do one of those.whatever I get rebuilt its going in my stock 81 c10 that came with a 250/th350.the truck is going to be used as a sunday driver only.which combo should i use.thanks mike
