I want my car done but......

I got an uncle that has been working on a '41 chevy, I kid you not he's been restoring this thing for 30 years. He takes one step forward and 10 backwards, talk about overwhelming. Had it running 5 years ago with a rebuilt 350 under the hood. He took it apart and sold it so he can buy a painless wiring kit and now he wants to put a 454 under the hood. I gave up helping him cause my hardwork is all for nothing. Then 3 years ago he started restoring a 82 GMC Sierra in hopes to flip it for funds for his 41. 10k into it, I mean 10k he could of spent for his 41!!!! Now this is overwhelming. 30 years of his life gone and a divorce over financial issues.
