ceddy2,
No matter if right or wrong, the biggest and most important fact of all is that he tried it all on his own! Congratulattions to the li'l boy!
Just a suggestion: tell him to buy a tech book like How to rebuild your small block chevy, it's quite inexpensive, quite easy reading and helps a lot a new guy makes things right the first time.
Again, his feat by no means is to be taken lightly, he is a great dude and deserve all respect!
