1965 Valiant

That is encouraging. After getting a better idea of how much engine work it needs, I'd start by considering what level of restoration I'd want to do, and what I'd like the total budget for the project to be. Do you want it to be light and/or powerful, with better brakes? Kept all original? Brought back to running condition but no further? If you have some time you can refurbish items on the cheap instead of buying reproduction parts. I just rebuilt my '64 Valiant sun visors for next to nothing. You can dolly those dents out yourself. Make a checklist of what the car needs.
