I have a 17 yr old grandson that may fill the bill, if he gets his grades up enough Only you are in charge of what you do, d what is best for you and yours. I'm getting closer on having my hot rod (1940 Ford 2dr. sedan)done and have two other cars that I want to do, bring back from half junk to decent running and looking, just need more money and tme A guy needs a reason to get up in the morning and it might as well be doing something you like and I like working on cars and motors I hope yours is to I will take you up on the exhaust advice as soon as I get the 527 back together and redynoed
