I have a buddy at work that was in the navy and he told me they used something to check for cracks using black light. Im sure its the same stuff. that sounds like exactly what i need. Im so ready to move forward with the machining and build I can hardly stand it, but i have a 16 year old daughter that Im going to surprise with a car for christmas so I want to wait on that. It just doesnt feel right to me to spend several thousand on a toy for me before i get her a car. My truck has a 305 in it now but it just doesnt have the power i want. Im in the guard and I work for the Department Of Defence and the way the economy is right now and the way my "comander and chief" seems to feel about the military Im a little worried about my job so I have to prioritise right now. Thanks for the advise. Any and all tips are greatly appreciated.
