Newbie here but have had the car forever

Hello! Long time listener, first time caller; I've been perusing the forums for quite some time to glean some knowledge. I've got a 1967 Barracuda with a 360/408 running through a 904 tranny making around 420hp, and not a whole lot on it is stock. I've had the car since 1995; bought it when I got out of active duty and have basically been throwing money at it ever since. Unfortunately I didn't do the work, and even more unfortunately I don't know a whole lot about engines (enough to get me in trouble, and that's about it) but I'm semi-retired and finally moving to a house with a shop big enough that I can do some work myself. It's a 408 and the damn thing likes to get hot, and recently it stalled on me and wouldn't start until it cooled down so I'll be doing a post about that soon.
