I did it myself on the cheap. I found a used OTC timing kit for 150. I cheeped out on the gaskets and kit from rock auto and went with Engine tech. The kit was garbage, and the gaskets needed a lot of cutting down. I do regret doing that. I have already had to replace the tensioners with cloyes. If I had to do it again, It would be all Cloyes gear, and felpro gaskets. I bought a used engine stand for 40 bucks, and borrowed a friends cherry picker. I bought all of my TTY parts and Ford OEM stuff from whitebear auto parts, so it was half or less then it was up here I think it was around 400 bucks. I ended up probably buying another 300 bucks in tools I didn't have. In the end, I figured I was around 1400 bucks Canadian out of pocket. I have already rented out my OTC kit twice for 50 dollars each time, so I made a bit back.
