wanted: Big block engine - NJ

Hey guys,
I am a member over on the B body site and visit here every now and then. I decided some of you may be able to help me. I'm looking for a big block for my 69' Roadrunner clone... I am a college student and don't have a ton of money to buy a brand new built engine but I have a decent amount saved up. So if you have anything interesting please let me know.
Thanks,
~Nick
