[Pont406]

I turned 40 already and been doing some thinking. My c10 is running good and I have another 461 strocker with 4l80e to go with c10. I have all the carbs, intake I will ever need to try.My car is done for the most part, Now i have all different parts laying around and so on. I dont have motivation to swap motors around. Few years back it was no brainer I just did it. I aslo thought about getting rid of all and buying something new.Maybe I need a brake from it for a while. What's your guys stragety? My gf is telling me that's a first sign of midlife crisis. Is that true? How do you guys deal with this?
