question for die hard original truck owners

[69chevytrucker]

this is just a question i was wondering if a 1969 c10 350 engine has any value or does it really matter if i were to toss it the engine i have is original from my 69 c10 but i have a diff engine in there cause the original seen better days bad lifters etc still ran when it was pulled but needs rebuild i just dont know if it worth anything i dont plan to rebuild it . but i would hate to chuck it if it would give a die hard a heart attack if you know what i mean.
